- BACKGROUND: Perivascular adipose tissue (PVAT) attenuation on computed tomography angiography reflects vascular inflammation. However, its prognostic value in patients undergoing endovascular aortic repair (EVAR) for abdominal aortic aneurysm (AAA) remains unclear. METHODS: We retrospectively studied consecutive patients who underwent EVAR for unruptured infrarenal AAA with preprocedural computed tomography angiography. PVAT attenuation and aortic characteristics were assessed using computed tomography angiography. The primary outcome was major adverse cardiac or cerebrovascular events (MACCE), a composite of all-cause death, myocardial infarction, stroke, and any vessel treatment. RESULTS: Among 275 patients treated with EVAR, 35.6% (98/275) experienced MACCE during a median follow-up of 3.5 years. Pre-EVAR PVAT attenuation was higher in patients who experienced MACCE than in those who did not (-69.8±10.3 HU versus -77.3±8.6 HU; P<0.001). In the Cox proportional hazards model, higher PVAT attenuation (per 10 HU; unadjusted hazard ratio, 1.88 [95% CI, 1.56-2.28]; P<0.001) was associated with MACCE after EVAR. Furthermore, higher PVAT attenuation was associated with AAA-related adverse events: a composite of AAA-related death, reintervention for AAA, embolization for endoleak, and AAA enlargement (per 10 HU; unadjusted hazard ratio, 2.16 [95% CI, 1.59-2.94]). Adding PVAT attenuation to post-EVAR prognostic factors and computed tomography angiography findings improved the predictive and reclassification abilities for MACCE after EVAR. CONCLUSIONS: In patients undergoing EVAR, higher PVAT attenuation was associated with both MACCE and AAA-related adverse events. PVAT attenuation may provide incremental prognostic value for identifying patients at higher risk of unfavorable outcomes following EVAR.2026年04月, Circulation.

- Objectives: The aim of our retrospective cohort study was to assess the influence of uterine balloon tamponade (UBT) prevalence on uterine artery embolization (UAE) in management of postpartum hemorrhage (PPH). Methods: This retrospective cohort study analyzed, as the final cohort, women with PPH who were transferred from other hospitals or clinics and underwent UAE at our university hospital. Initial UAE success was defined as achieving hemostasis with the first UAE procedure. The use rates of UAE, UAE success rates, and UAE procedural times were compared between the pre-UBT period (January 2009–December 2014) and the UBT period (January 2015–December 2023). Results: In the pre-UBT period, 29 of 41 women with PPH underwent UAE. In the UBT period, 21 of 121 women received UAE following UBT, whereas 11 underwent UAE without prior UBT. The use rate of UAE was significantly higher in the pre-UBT period than in the UBT period (70.7% vs. 26.4%; p < 0.01). There were no significant differences in the initial (72.4% vs. 81.3%; p = 0.55) or final (82.8% vs. 87.5%; p = 0.72) success rates of UAE between the two periods. The procedural time of the initial UAE in the UBT period tended to be longer than that in the pre-UBT period (46 min vs. 61 min; p = 0.07). Conclusions: The introduction of UBT was associated with a reduced use rate of UAE, but it did not significantly affect the success rate or procedural time of UAE in the management of PPH.MDPI AG, 2026年01月, Journal of Clinical Medicine, 15(2) (2), 416 - 416研究論文(学術雑誌)

- Purpose: We conducted a prospective study to evaluate the usefulness of ultralow-dose computed tomography (ULD-CT) with deep-learning reconstruction (DLR) compared with conventional standard-dose CT (SD-CT) for post-endovascular aneurysm repair (EVAR) surveillance. Materials and Methods: We prospectively performed post-EVAR surveillance using ULD-CT at a single center in 44 patients after they had received SD-CT. The ULD-CT images underwent DLR, whereas the SD-CT images underwent iterative reconstruction. Three radiologists blinded to the patient information and CT conditions independently measured the aneurysmal sac diameter and evaluated the overall image quality. Bland–Altman analysis and a linear mixed-effects model were used to assess and compare the measurement accuracy between SD-CT and ULD-CT. Results: The mean CT dose index volume and dose–length product were significantly lower for ULD-CT (1.0 ± 0.3 mGy and 71.4 ± 26.5 mGy•cm) than that for SD-CT (6.9 ± 0.9 mGy and 500.9 ± 96.0 mGy•cm; p<0.001). The mean short diameters of the aneurysmal sac measured by the 3 observers were 46.7 ± 10.8 mm on SD-CT and 46.3 ± 10.8 mm on ULD-CT. The mean difference in the short diameter of the aneurysmal sac between ULD-CT and SD-CT was −0.37 mm (95% confidence interval, −0.6 to −0.12 mm). The intraobserver limits of agreement (LOA) for measurements by ULD-CT and SD-CT were −3.5 to 2.6, −2.8 to 1.9, and −2.9 to 2.3 for Observers 1, 2, and 3, respectively. The pairwise LOAs for assessing interobserver agreement, such as for the differences between Observers 1 and 2 measurements in SD-CT, were mostly within the predetermined acceptable range. The mean image-quality score was lower for ULD-CT (3.3 ± 0.6) than that for SD-CT (4.5 ± 0.5; p<0.001). Conclusion: Aneurysmal sac diameter measurements by ULD-CT with DLR were sufficiently accurate for post-EVAR surveillance, with substantial radiation reduction versus SD-CT. Clinical Impact Deep-learning reconstruction (DLR) is implemented as a software-based algorithm rather than requiring dedicated hardware. As such, it is expected to be integrated into standard computed tomography (CT) systems in the near future. The ultralow-dose CT (ULD-CT) with DLR evaluated in this study has the potential to become widely accessible across various institutions. This advancement could substantially reduce radiation exposure in post-endovascular aneurysm repair (EVAR) CT imaging, thereby facilitating its adoption as a standard modality for post-EVAR surveillance.SAGE Publications, 2025年06月, Journal of Endovascular Therapy研究論文(学術雑誌)

- Although transcatheter arterial embolization is the first choice treatment for renal arteriovenous malformation. Renal arteriovenous malformation with dilated venous sac can cause venous pulmonary thromboembolism after transcatheter arterial embolization. A woman in her 60s was diagnosed with a left renal arteriovenous malformation and an 8 cm venous sac with renal dysfunction after right renal arteriovenous malformation treatment. We performed a hybrid treatment of transcatheter arterial embolization and sequential vein ligation to reduce the risk of lethal thrombotic complications. After treatment, the left renal arteriovenous malformation disappeared without fatal complications, and the venous sac shrunk with the preservation of renal function as it was before the hybrid treatment. When performing embolization of renal arteriovenous malformation with a huge venous sac, hybrid treatment of arterial embolization and surgical vein ligation may be safe and useful for preventing fatal post-operative thrombotic complications.2025年03月, Interventional radiology (Higashimatsuyama-shi (Japan), 10, e20240005, 英語, 国内誌研究論文(学術雑誌)

- PURPOSE: The purpose of the study was to evaluate the efficacy and safety of pre-emptive transcatheter arterial embolization (P-TAE) of aortic side branches to prevent type II endoleak in patients with abdominal aortic aneurysm after endovascular abdominal aneurysm repair (EVAR). MATERIALS AND METHODS: This multicenter, prospective, single-arm trial enrolled 100 patients with abdominal aortic aneurysm from nine hospitals between 2018 and 2021. There were 85 men and 15 women, with a mean age of 79.6 ± 6.0 (standard deviation) years (range: 65-97 years). P-TAE was attempted for patent aortic side branches, including the inferior mesenteric artery, lumbar arteries, and other branches. The primary endpoint was late type II endoleak incidence at 6 months post-repair. Secondary endpoints included changes in aneurysmal sac diameter at 6- and 12 months, complications, re-intervention, and aneurysm-related mortality. Aneurysm sac changes at 6- and 12 months was compared between the late and no-late type II endoleak groups. RESULTS: Coil embolization was successful in 80.9% (321/397) of patent aortic side branches, including 86.3% of the inferior mesenteric arteries, 80.3% of lumbar arteries, and 55.6% of other branches without severe adverse events. Late type II endoleak incidence at 6 months was 8.9% (8/90; 95% confidence interval: 3.9-16.8%). Aneurysm sac shrinkage > 5 mm was observed in 41.1% (37/90) and 55.3% (47/85) of the patients at 6- and 12-months post-EVAR, respectively. Patients with late type II endoleak had less aneurysm sac shrinkage than those without type II endoleak at 12 months (-0.2 mm vs. -6.0 mm; P = 0.040). No patients required re-intervention for type II endoleak, and no aneurysm-related mortalities occurred. CONCLUSION: P-TAE is safe and effective in preventing type II endoleak, leading to early sac shrinkage at 12 months following EVAR.2024年03月, Diagnostic and interventional imaging, 英語, 国際誌研究論文(学術雑誌)
- PURPOSE: The occurrence of endoleaks, particularly type 2 endoleaks (EL2), is the primary cause of poor long-term prognosis after endovascular aneurysm repair (EVAR). This study aimed to evaluate the efficacy and safety of preemptive transcatheter arterial embolization (P-TAE) for aortic side branches (ASBs) to prevent EL2 before EVAR using the Excluder stent-graft system (EXCLUDER). MATERIALS AND METHODS: In this prospective, multicenter study, 80 patients (mean age, 79.1±6.7 years; 85.0% male patients; mean aneurysmal sac diameter, 48.4±7.4 mm) meeting the eligibility criteria were prospectively enrolled from nine hospitals. Before EVAR, p-TAE was performed to embolize the patent ASBs originating from the abdominal aortic aneurysm. Contrast-enhanced computed tomography was performed at 1 month and 6 months after EVAR. The primary endpoint was EL2 incidence at 6 months, and the secondary endpoints were aneurysmal sac diameter changes at 6 and 12 months, P-TAE outcomes, complications related to P-TAE, re-intervention, and aneurysm-related mortality. RESULTS: All patients successfully underwent P-TAE without serious complications. Coil embolization was successful in 81.6% of ASBs. EL2 incidence at 6 months was identified in 18/70 (25.7%) patients. Aneurysmal sac diameter shrinkage (≥5 mm) was observed in 30.0% of patients at 6 months and in 40.9% at 12 months. Only one patient required re-intervention for EL2 within 1 year of EVAR; aneurysm-related deaths were not observed. CONCLUSION: P-TAE for ASBs before EVAR using EXCLUDER is a safe and effective strategy. It aids in achieving early aneurysmal sac shrinkage and reduces EL2 re-intervention at 1 year after EVAR.2024年03月, Journal of vascular and interventional radiology : JVIR, 英語, 国際誌[査読有り]研究論文(学術雑誌)
- We report a case of a life-threatening ruptured renal angiomyolipoma (AML) that did not meet the criteria for prophylactic treatment (tumor >4 cm or intratumoral aneurysm >5 mm) during follow-up. A woman in her 70s was followed up for a 2.5-cm AML with a rich vascular component. An intratumoral aneurysm >5 mm was not identified for 2 years. She complained of a sudden abdominal pain with hypotension, and contrast-enhanced computed tomography revealed a retroperitoneal hematoma with contrast media extravasation from an intratumoral aneurysm. Emergency transcatheter arterial embolization was successfully performed using N-butyl cyanoacrylate glue. Rupture can occur in small AMLs or in AMLs not identified with intratumoral aneurysms during follow-up. AMLs with a rich vascular component at the kidney surface are more likely to rupture.2024年03月, Interventional radiology (Higashimatsuyama-shi (Japan), 9(1) (1), 20 - 25, 英語, 国内誌

- Right-sided ligamentum teres (RSLT) is a rare congenital anomaly in which the fetal umbilical vein is connected to the right paramedian trunk of the portal vein. An 80-year-old woman underwent curative sigmoidectomy for sigmoid cancer 3 years prior to presentation. After 1 year, small solitary liver metastasis was noted in segment 4. Because the patient experienced recurrence of the same lesion after chemotherapy and radiofrequency ablation, she was referred to our hospital. CT revealed an anomaly of the liver with RSLT, classified as an independent posterior branch type. The tumor in the left paramedian section was located in the right umbilical portion (RUP), and BDTT was advanced to the common bile duct. Because the estimated future remnant liver volume was 35.2%, transileocecal portal vein embolization (PVE) for the portal branches from the RUP increased it to 43.5% in 3 weeks. Left trisectionectomy with extrahepatic bile duct resection and hepaticojejunostomy were performed. The patient was discharged on postoperative day 75. We successfully performed a left trisectionectomy after PVE in a patient with RSLT. Understanding the vascular and biliary anomalies of patients with RSLT is essential. When the future remnant liver is small, PVE can be considered for safe hepatectomy.Springer Science and Business Media LLC, 2022年09月, Clinical Journal of Gastroenterology, 15(6) (6), 1130 - 1135, 英語, 国内誌[査読有り]研究論文(学術雑誌)
- Abstract Background Spinal fractures rarely cause hemothorax, and no treatment consensus has been reached. Conservative treatment is generally selected in cases without arterial injury, but there have been some reports of uncontrolled bleeding. Here we report a case of hemothorax caused by spinal fracture without arterial injury treated with transcatheter arterial embolization. Case presentation An 88-year-old Japanese woman with back pain was diagnosed with hemothorax due to bleeding from an unstable fracture of the tenth thoracic vertebra. Contrast-enhanced computed tomography revealed no obvious arterial injury. We performed transcatheter arterial embolization of the bilateral tenth intercostal arteries to prevent rebleeding. The hemothorax did not worsen until surgical spinal fixation 9 days post-transcatheter arterial embolization, and she was discharged 30 days after admission. Conclusion Transcatheter arterial embolization for hemothorax caused by spinal fractures without obvious arterial injury may be a useful bridge to spinal fixation.Springer Science and Business Media LLC, 2022年09月, Journal of Medical Case Reports, 16(1) (1), 332 - 332, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- Hereditary hemorrhagic telangiectasia (HHT) is a risk of infection, such as by brain abscess associated with pulmonary arteriovenous malformations. However, association between HHT and recurrent erysipelas is not well described. HHT can cause vessel malformations in organs, leading to various serious outcomes. Prophylactic treatment is effective, but many people with HHT are undiagnosed. HHT is not described as a risk factor for soft tissue infection, but may increase the risk of serious infections requiring hospitalization. Our 72-year-old female patient was admitted for recurrent erysipelas. Pulmonary nodules indicated pulmonary arteriovenous fistula on chest computed tomography. By recognizing this combination, although seemingly unrelated problems, we could diagnose HHT and the patient could receive adequate treatment to prevent life-threatening events. The recurrent erysipelas was likely associated with HHT. Recurrent erysipelas is an important presentation which may facilitate early diagnosis of HHT.Edizioni Internazionali srl, Divisione EDIMES Edizioni Medico-Scientifiche, 2022年03月, Infezioni in Medicina, 30(1) (1), 129 - 133, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- PURPOSE: The purpose is to investigate the major and minor complications of the pancreas after transcatheter arterial embolization (TAE) using n-butyl-2-cyanoacrylate (NBCA) for bleeding from pancreatic arteries. MATERIALS AND METHODS: Thirty-three patients who underwent TAE using NBCA for acute bleeding from pancreatic arteries and their parent arteries followed by contrast-enhanced computed tomography (CE-CT) were evaluated retrospectively. Complications and risk factors were assessed using Mann-Whitney U test or Fisher's exact test for the univariate analysis. Patients' characteristic, embolized artery, procedure details, and clinical outcomes were examined as possible risk factors. RESULTS: TAE was performed successfully in all patients. Minor pancreatic complications occurred in 10 patients (30%), including acute mild pancreatitis (n = 4) and focal lack of pancreatic parenchymal enhancement on CE-CT without pancreatitis (n = 6). No cases of major pancreatic complications, such as moderate/severe pancreatitis, were reported. Embolized artery was the only significant risk factor. The rate of complications per embolized artery were 15% (three out of 20 patients) in the arteries of the pancreatic head and 54% (seven out of 13 patients) in the arteries of pancreatic body and tail (p = 0.025). CONCLUSION: TAE using NBCA for acute bleeding from pancreatic arteries is efficacious and safe. Mild pancreatic complications were observed more frequently in case of embolization of the pancreatic body and tail region than the pancreatic head.2021年10月, Japanese journal of radiology, 40(3) (3), 308 - 317, 英語, 国内誌[査読有り]研究論文(学術雑誌)

Abstract Purpose To evaluate the efficacy of superselective transcatheter arterial embolization (TAE) for intractable postpartum hemorrhage (PPH) due to genital tract trauma (GTT) after vaginal delivery.Methods We evaluated 27 patients who underwent TAE for intractable PPH due to GTT after vaginal delivery at our institution between January 2008 and December 2020. Patients were divided into two groups according to TAE procedure; TAE performed as close as possible to the bleeding point, at least more peripherally than the second branch of the anterior division of the internal iliac artery, was defined as superselective TAE (S-TAE). TAE performed from the proximal segment of the internal iliac artery was defined as proximal TAE (P-TAE). Patient characteristics, pre-procedural contrast-enhanced computed tomography (CE-CT), procedure details, technical/clinical success, and complications were evaluated separately for the S-TAE and P-TAE groups.Results The combined technical/clinical success rate was 92%. No major procedure-related complications were seen (mean follow-up: 6.12 ± 3.93 days). The combined technical/clinical success rate of S-TAE was 100% and of P-TAE was 67% (p = 0.04). S-TAE was performed more frequently in patients with pre-procedural CE-CT (p = 0.01) and use of permanent embolic materials (p = 0.003).Conclusion S-TAE is safe and effective for intractable PPH due to GTT. Pre-procedural CE-CT may be useful for detecting the culprit artery and be helpful in performing S-TAE.[査読有り]研究論文(学術雑誌) - SAGE Publications, 2021年07月, Acta Radiologica Open, 10(7) (7), 205846012110349 - 205846012110349, 英語, 国際誌
Background Technological developments have led to an increased usage of external-body radiotherapy (RT) for the treatment of hepatocellular carcinoma (HCC). Transcatheter arterial chemoembolization (TACE) may be required later in patients treated with RT because of the high recurrence rate and multinodular presentation of HCC. However, despite the risk of liver function impairment, the cumulative liver damage correlated with TACE following a hepatic RT has not been adequately assessed.Purpose To evaluate the feasibility of TACE following RT for HCC.Materials and methods Sixty-seven patients with HCC who underwent TACE after RT were retrospectively evaluated between 2012 and 2018. We assessed increases in Child–Turcotte–Pugh (CTP) by ≥2 points at 1 month, the incidence of major complications, survival duration, and short-term mortality within 6 months after TACE. Furthermore, we evaluated the predictive factors for liver function impairment and short-term mortality.Results Eight patients experienced a CTP increase ≥2 points at 1 month. There were no cases of liver abscesses or bilomas. Nine patients died within 6 months following TACE. The mean liver dose (MLD) was a significant predictor of liver function impairment at 1 month ( p = 0.042). Low liver functional reserve, distant metastasis ( p = 0.037), MLD ( p = 0.046), TACE type ( p = 0.025), and TACE within 3 months following RT ( p = 0.007) were significant predictors of short-term mortality.Conclusions Despite the feasibility of TACE following RT, clinicians should pay attention to impaired pretreatment liver function, following high dose RT, and the short duration between RT and TACE.[査読有り]研究論文(学術雑誌) - BACKGROUND: Preoperative prediction of thromboembolic complications using magnetic resonance imaging (MRI) in coronary arteries and carotid arteries has been established. However, the technique has not been applied in peripheral arteries. This study aimed to assess the relationship between thromboembolic complications during endovascular treatment (EVT) for iliac artery occlusion and signal intensity on MRI. METHODS: This single-institution study included 52 iliac artery occlusions in 51 patients (mean age, 70.4 years) who underwent successful EVT between January 2010 and March 2018. MRI using an inversion recovery-prepared, steady-state free precession technique was performed preoperatively. Thromboembolic complications were defined as distal embolization and in-stent protrusion greater than 25% of the stent cross-sectional area confirmed by angiography and intravascular ultrasonography, regardless of symptoms. The highest signal intensity of iliac artery occlusion divided by the signal intensity of adjacent iliopsoas muscle (target-to-muscle ratio, TMR) was measured on MR images. Multivariate analysis was performed to clarify the predictors of thromboembolic complications during EVT. RESULTS: Thromboembolic complications observed in 11 vessels (21.2%) from 11 patients comprised distal embolization (n = 4) and in-stent protrusion (n = 7). A TMR cutoff value > 2.57 had a sensitivity of 90.9%, specificity of 78.0%, positive predictive value of 52.6%, and negative predictive value of 97.0% for detecting thromboembolic complications during EVT. In the multivariate analysis, TMR >2.57 was the only independent factor associated with thromboembolic complications (odds ratio, 30.10; 95% confidence interval, 3.26-278.00; P = 0.003). CONCLUSIONS: The presence of higher signal intensity in iliac artery occlusion on MRI is useful for predicting thromboembolic complications during EVT.2021年05月, Annals of vascular surgery, 73, 211 - 221, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- PURPOSE: To assess the utility of whole-aorta CT angiography (CTA) with 15 mL contrast material (CM) on time-resolved imaging for endovascular abdominal aortic repair (EVAR). METHODS: Twenty-six patients with a high-risk of post-contrast acute kidney injury (PC-AKI) underwent CTA with 15 mL CM using temporal maximum intensity projection (tMIP-CTA) generated from time-resolved imaging. The aortoiliac CT values were measured. Two observers measured the arterial diameters in unenhanced CT and tMIP-CTA images, and image quality was evaluated on a 5-point scale. The presence of the accessory renal artery, inferior mesenteric artery (IMA) occlusion, and instructions for use (IFU) of EVAR were evaluated. RESULTS: CT examinations were successfully performed, and no patients developed PC-AKI. The mean CT values of the whole aorta were 267.5 ± 51.4 HU, which gradually decreased according to the distal levels of the aorta. Bland-Altman analysis revealed excellent agreement for the external arterial diameter measurements between unenhanced CT and tMIP-CTA. Excellent interobserver agreement was achieved for the measurements of the external (ICCs, 0.910-0.992) and internal arterial diameters (ICCs, 0.895-0.993). Excellent or good overall image quality was achieved in 24 (92 %) patients. The presence of the accessory renal artery, IMA occlusion and the assessment of IFU were in 100 % agreement. Multivariate analysis revealed aortic volume as the most significant independent factor associated with strong aortic enhancement (p = 0.004). CONCLUSIONS: Whole-aorta tMIP-CTA on time-resolved imaging is useful for maintaining contrast enhancement and image quality for EVAR planning, and can substantially reduce the amount of CM.2020年05月, European journal of radiology, 126, 108861 - 108861, 英語, 国際誌[査読有り]研究論文(学術雑誌)
- PURPOSE: To evaluate the mid-term outcomes of transarterial embolization (TAE) for type II endoleak after endovascular abdominal aortic aneurysm repair (EVAR) and investigate the predictors of sac enlargement after embolization. MATERIALS AND METHODS: We conducted a retrospective analysis of 55 patients [48 men and 7 women, median age 79.0 (interquartile ranges 74-82) years] who underwent TAE for type II endoleak from 2010 to 2018. The aneurysmal sac enlargement, endoleaks, aneurysm-related adverse event rate, and reintervention rate were evaluated. Patients' characteristics and clinical factors were evaluated for their association with sac enlargement. RESULTS: Fifty-five patients underwent TAE with technical success and were subsequently followed for a median of 636 (interquartile ranges 446-1292) days. The freedom from sac enlargement rates at 1, 3, and 5 years was 73.2%, 32.0%, and 26.7%, respectively. After initial TAE, the recurrent type II, delayed type I, and occult type III endoleak were identified in 39 (71%), 5 (9%), and 3 (5%) patients, respectively. Although a patient had aorto-duodenal fistula, there was no aneurysm-related death. The freedom from reintervention rates was 84.6%, 35.7%, and 17.0%, respectively. In the multivariate analysis, sac diameter > 55 mm at initial TAE (hazard ratios, 3.23; 95% confidence intervals, 1.22-8.58; P < 0.05) was a significant predictor of sac enlargement. CONCLUSION: TAE for type II endoleak was not effective in preventing sac enlargement, and reinterventions were required among the mid-term follow-up. The sac diameter > 55 mm at initial TAE was a significant predictor of sac enlargement.2020年05月, Cardiovascular and interventional radiology, 43(5) (5), 696 - 705, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- PURPOSE: To assess the safety and efficacy of transarterial embolization (TAE) and to evaluate the utility of contrast-enhanced computed tomography (CE-CT) for life-threatening spontaneous retroperitoneal hemorrhage (SRH). METHODS: Nineteen patients underwent TAE following CE-CT for life-threatening SRH. CE-CT and angiographic findings, technical successes, and clinical successes were evaluated. The diagnostic performance of CE-CT for the detection of active bleeding arteries was also assessed by two independent readers. RESULTS: Active extravasation of contrast material was accurately observed in 78.9‒84.2% of the patients on CE-CT. Angiograms revealed active extravasation in 37 arteries of 15 patients (78.9%), and 4 patients showed no sign of active bleeding. Sensitivity, positive predictive value, and accuracy rate of CE-CT for the detection of active bleeding vessels was 59.5%, 62.9‒71.0% and 55.6‒60.0% respectively. The successful embolization of 48 intended arteries was achieved in all the patients, including empirical TAE in four patients. Hemodynamic stabilization was achieved in 17 patients (89.5%) with a significant decrease in transfusion (p < 0.001). CONCLUSION: TAE is a technically safe and clinically effective treatment method for life-threatening SRH. CE-CT has moderate capability for accurate identification of active bleeding arteries. TAE including arteries that potentially distribute anatomic territory of the hematoma is essential.2019年04月, Japanese journal of radiology, 37(4) (4), 328 - 335, 英語, 国内誌[査読有り]研究論文(学術雑誌)
- PURPOSE: To evaluate the advantages of intraprocedural CT during adrenal venous sampling (AVS) to confirm accurate catheterization of the right adrenal vein (RAV). MATERIALS AND METHODS: This single-institution study included 106 patients (mean age 52.4 years; range 28-74 years) with primary aldosteronism who performed contrast-enhanced CT (CECT) before AVS following AVS between January 2011 and March 2018. After catheterization of the RAV under fluoroscopic guidance, unenhanced CT images were obtained to confirm catheter position on unified CT angiography system. Catheter repositioning was performed when the catheter was inaccurately positioned. Venography findings were classified into two groups: (1) presumably cannulated in the RAV (presumed RAV group) and (2) obscured visualization of the RAV because of collateral vessels (obscured RAV group). Success rates of AVS were compared using Fisher's exact test. RESULTS: The overall success of AVS was achieved in 104 patients (98.1%). Catheter was deviated into the IVC during intraprocedural CT in four patients. Fourteen patients (14.0%) required catheter repositioning by intraprocedural CT images, and accurate catheterization in the RAV was eventually accomplished. The success rate of AVS was significantly higher in the presumed RAV group (90.1% [73/81]) than that in the obscured RAV group (68.4% [13/19]) (p = 0.024). If intraprocedural CT was not acquired during AVS, the success rate of AVS would have been significantly lower (84.9% [90/106]) compared with that use of intraprocedural CT (98.1% [104/106]) (p < 0.001). CONCLUSIONS: Intraprocedural unenhanced CT by referring to the preprocedural CECT before AVS enables the confirmation of accurate catheterization of the RAV.

- OBJECTIVE: To evaluate the impact of white matter changes on neurologic outcomes after total arch replacement using antegrade cerebral perfusion. METHODS: White matter changes were assessed using a visual Fazekas scale on preoperative magnetic resonance images. From October 1999 to December 2016, 359 patients who had demonstrated changes on preoperative magnetic resonance imaging underwent elective total arch replacement using antegrade cerebral perfusion. Patients were classified into 3 severity groups: mild (100 patients), moderate (158 patients), and severe (101 patients). Mean follow-up time was 4.8 ± 3.6 years. Multivariate logistic regression methods were used to evaluate for an independent association between white matter changes and postoperative neurological outcomes. RESULTS: Hospital mortality was 2.8% (10/359), and no significant differences were found across the 3 groups (P = .604). Multivariate analysis demonstrated that the severity of white matter change was significantly associated with both postoperative permanent neurologic deficit (odds ratio, 5.77; 95% confidence interval, 1.58-38.4, P = .005) and transient neurologic deficit (odds ratio, 2.46; 95% confidence interval, 1.45-4.37, P < .001). CONCLUSIONS: White matter changes, defined using the visual Fazekas scale on preoperative magnetic resonance imaging, were significantly associated with significant postoperative adverse neurologic outcomes after total arch replacement using antegrade cerebral perfusion.2019年04月, The Journal of thoracic and cardiovascular surgery, 157(4) (4), 1350 - 1357, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- Following up patients after coil embolization with non-invasive imaging such as CT or MRI is important to evaluate recanalization, surrounding and distal organ ischemia and complications, but can be difficult due to metal artifact or other factors. In this article, the characteristics of X-ray, CT and MRI to assess post-embolization state were addressed. The recent trend including dual energy CT, metal artifact reduction algorithm on CT, and sequences for MR angiography were summarized with some clinical cases.一般社団法人日本インターベンショナルラジオロジー学会, 2018年, 日本インターベンショナルラジオロジー学会雑誌, 33(2) (2), 137 - 143, 日本語[査読有り]研究論文(学術雑誌)
- ADLが杖歩行の70代の女性が約1メートル四方の自宅玄関で転倒,両側股関節と左膝関節を屈曲し,右膝関節を伸展した状態で動けなくなった。本人が医療機関への受診を拒否したため,家族が水分や食事を与え2週間経過したが,徐々に衰弱したため救急要請された。救急隊の観察にて上記異常肢位に加え,左大腿に開放骨折創があり,同部から膿汁の流出を認めた。受傷機転より体位性圧挫症候群の発症が危惧されたため,ドクターカーが要請された。現場にて輸液投与し,体位変換を行わずに搬送を行った。搬送中も心室性不整脈を呈さず,初療室にて無動化の後に体位整復を行い,圧迫を解除した。最終的に左股関節離断に至ったが,長期にわたり同一肢位を強制されていた割には致命的な合併症を認めなかった。その要因として下肢血流が保たれ自動運動が辛うじて可能で,左大腿開放骨折創から軟部組織のドレナージがされ,水分摂取により腎不全に至らなかったことが示唆された。Japanese Society for Emergency Medicine, 2015年10月, 日本臨床救急医学会誌, 18(5) (5), 686 - 690, 日本語[査読有り]研究論文(学術雑誌)
