BACKGROUND: Acute portal vein thrombosis (PVT) with bowel necrosis is a fatal condition with a 50%-75% mortality rate. This report describes the successful endovascular treatment (EVT) of two patients with severe PVT. CASE SUMMARY: The first patient was a 22-year-old man who presented with abdominal pain lasting 3 d. The second patient was a 48-year-old man who presented with acute abdominal pain. Following contrast-enhanced computed tomography, both patients were diagnosed with massive PVT extending to the splenic and superior mesenteric veins. Hybrid treatment (simultaneous necrotic bowel resection and EVT) was performed in a hybrid operating room (OR). EVTs, including aspiration thrombectomy, catheter-directed thrombolysis (CDT), and continuous CDT, were performed via the ileocolic vein under laparotomy. The portal veins were patent 4 and 6 mo posttreatment in the 22-year-old and 48-year-old patients, respectively. CONCLUSION: Hybrid necrotic bowel resection and transileocolic EVT performed in a hybrid OR is effective and safe.

BACKGROUND: A congenital intrahepatic portosystemic shunt (IPSVS) is a rare vascular abnormality that is characterized by an anomalous intrahepatic venous tract that connects the intrahepatic portal vein with the hepatic venous system. Hepatic encephalopathy is an indication for IPSVS embolization, which is technically challenging because rapid blood flow through shunts can induce the migration of embolization material to systemic veins. This case report discusses the efficacy of percutaneous balloon-occluded retrograde transvenous obliteration for treating patients with IPSVSs. CASE SUMMARY: A 75-year-old woman presented with a six-month history of repeated hepatic encephalopathy due to an IPSVS without liver cirrhosis. We successfully embolized the IPSVS using percutaneous balloon-occluded retrograde transvenous obliteration with interlocking detachable coils. After the procedure, the patient exhibited no symptoms of hepatic encephalopathy for 14 mo. CONCLUSION: Balloon-occluded retrograde transvenous obliteration with detachable coils can be effective for the endovascular treatment of an IPSVS.

PURPOSE: The purpose of the study is to evaluate the initial and midterm efficacy and safety of endovascular treatment (EVT) using Viabahn stent-graft (SG) for arterial injury and bleeding (AIB) at the visceral arteries. MATERIALS AND METHODS: Consecutive patients with visceral AIB who underwent EVT using Viabahn between January 2017 and February 2021 were retrospectively reviewed. Technical success, clinical success, peripheral organ ischemia, peri-procedural complications, bleeding-related mortality, 30-day mortality, neck length, re-bleeding, endoleaks, and patency of the SGs at 1, 3, 6, and 12 months were evaluated. RESULTS: EVT using Viabahn was performed in 14 patients (mean age: 68.6 years; 12 males) and 15 arteries. The technical and clinical success rates were 100%. The rates of peripheral organ ischemia, peri-procedural complications, bleeding-related mortality, and 30-day mortality were all 0%. The mean neck length was 9.9 mm. No endoleaks or re-bleeding occurred during the follow-up (mean: 732 days). The SG patency was confirmed after 1, 3, 6, and 12 months in 78.6%, 78.6%, 78.6%, and 56.1% of the patients, respectively. CONCLUSION: EVT using Viabahn for AIB at the visceral arteries was safe and effective. SG occlusions without ischemia often occurred after 12 months.

BACKGROUND: A Viabahn stent graft (SG) is a heparin-coated self-expandable SG for lower extremity arterial disease that exhibits high flexibility and accuracy in the delivery system. This study aimed to evaluate the short-term efficacy and safety of emergency endovascular treatment (EVT) using a Viabahn SG for upper and lower extremity arterial bleeding (ULEAB). METHODS: Consecutive patients with ULEAB who underwent emergency EVT using the Viabahn SG between January 2017 and August 2021 were retrospectively reviewed. The indications for EVT, location of artery, technical success, clinical success, limb ischemia, periprocedural complications, bleeding-related mortality, 30-day mortality, diameter of the target artery, diameter of the SG, neck length, rebleeding, endoleaks, and patency of the SGs at 1, 3, 6, and 12 months were evaluated. RESULTS: EVT using the Viabahn SG was performed in 22 patients (mean age, 72.0 ± 13.0 years; 11 men) and 23 arteries (upper, 6; lower, 17). The indications for EVT were pseudoaneurysm (n = 13, 59.1%), extravasation (n = 9, 39.1%), and inadvertent arterial cannulation (n = 1, 4.3%). The anatomical locations of the 23 ULEAB injuries were the brachiocephalic (1 [4.3%]), subclavian (3 [13.0%]), axillary (1 [4.3%]), brachial (1 [4.3%]), common iliac (4 [17.4%]), external iliac (8 [34.8%]), common femoral (2 [8.7%]), superficial femoral (2 [8.7%]), and popliteal (1 [4.3%]) arteries. The technical and clinical success rates were 100%. The rates of limb ischemia, periprocedural complications, and bleeding-related mortality were 0%, whereas the 30-day mortality rate was 22.7%. The mean diameters of the arteries and SGs were 7.7 ± 2.2 and 8.9 ± 2.3 mm, respectively. The mean neck length was 20.4 ± 11.3 mm. No endoleaks or rebleeding occurred during the follow-up period (mean, 169 ± 177 days). Two SG occlusions without limb ischemia occurred in the external iliac and brachial arteries after 1 and 4 months, respectively. Subsequently, cumulative SG patency was confirmed after 1, 3, 6, and 12 months in 91.7%, 91.7%, 81.5%, and 81.5% of patients, respectively. CONCLUSIONS: Emergency EVT using the Viabahn SG for ULEAB was effective and safe according to short-term outcomes. Appropriate size selection and neck length are important for successful treatment. SG patency was good after 1, 3, 6, and 12 months.

BACKGROUND: Although the high-attenuating crescent (HAC) sign can indicate aortic aneurysm (AA) impending rupture, the relation of its computed tomography (CT) value to the aneurysmal status remains unclear. This study compared the HAC sign CT-attenuation values among rupture, impending rupture, and non-rupture AA cases.Methods and Results:This included 76 patients (mean age: 77.0 years) diagnosed with HAC sign-associated AA between January 2005 and July 2015. The CT-attenuation values of the HAC sign (H) and aortic lumen (A) using region-of-interest methodology were measured and the H/A ratio was calculated. The study classified patients into the rupture group (R-G, n=36), impending rupture group (IR-G, n=16), and non-rupture group (NR-G, n=24); the H and the H/A ratio were compared among them. Additionally, the H and the H/A ratio cut-offs between the IR-G and NR-G groups were evaluated. The H and the H/A ratio were significantly higher in the R-G and IR-G than in the NR-G (both P<0.001); the H/A ratio was significantly higher in the R-G than in the IR-G (P=0.038). The optimal cut-off for H between the IR-G and NR-G was 50.3 Hounsfield units (area under the curve [AUC]=0.875; sensitivity=87.5%; specificity=87.5%), and that for the H/A ratio was 1.3 (AUC=0.909; sensitivity=91.7%; specificity=87.5%). CONCLUSIONS: Among patients with AA, the H and the H/A ratio were significantly higher in cases of rupture and impending rupture than in those of non-rupture.

PURPOSE: Temperature alteration can modify the polymerization of n-butyl cyanoacrylate (NBCA)-iodized oil mixtures during vascular embolization; its effects on viscosity, polymerization time, and intra-arterial distribution of the NBCA-iodized oil mixture were investigated. MATERIALS AND METHODS: In vitro, the viscosities of NBCA, iodized oil, and NBCA-iodized oil mixtures (ratio, 1:1-8) were measured at 4-60 ºC using a rotational rheometer. The polymerization times (from contact with blood plasma to stasis) were recorded at 0-60 ºC using a high-speed video camera. In vivo, the 1:2 mixture was injected into rabbit renal arteries at 0, 20, and 60 ºC; intra-arterial distribution of the mixture was pathologically evaluated. RESULTS: The mixtures' viscosities decreased as temperature increased; those at 60 ºC were almost four to five times lower than those at 4 ºC. The polymerization time of NBCA and the 1:1-4 mixtures increased as temperature decreased in the 0-30 ºC range; the degree of time prolongation increased as the percentage of iodized oil decreased. The 0 ºC group demonstrated distributions of the mixture within more peripheral arterial branches than the 20 and 60 ºC groups. CONCLUSION: Warming reduces the mixture's viscosity; cooling prolongs polymerization. Both can be potential factors to improve the handling of NBCA-iodized oil mixtures for lesions requiring peripheral delivery. Temperature alteration influences the polymerization time, viscosity, and intra-arterial distribution of NBCA-iodized oil mixtures. Warming reduces the viscosity of the mixture, while cooling prolongs polymerization.

BACKGROUND: To evaluate outcomes of endovascular treatment (EVT) using a combination of multiple endovascular techniques for acute lower limb ischemia (ALLI) and to compare outcomes based on vessel type and artery location. METHODS: A total of 95 consecutive patients with ALLI (mean age, 72.0 years; 65 males; 104 lower limbs) who received emergency EVT using a combination of multiple endovascular techniques including thrombolysis, aspiration thrombectomy, stenting, and balloon angioplasty with or without surgical thromboembolectomy, between January 2005 and December 2017 were included. Vessel type was classified into native artery occlusion (native occlusion) and bypass graft occlusion (graft occlusion), including prosthetic and vein graft. Additionally, native arteries were categorized into below-knee occlusion and non-below-knee occlusion. Technical success, perioperative death (POD), ALLI-related death, amputation, amputation-free survival (AFS), and complications were compared according to vessel type (native occlusion vs. graft occlusion) and artery location (below-knee occlusion vs. non-below-knee occlusion). RESULTS: Of all patients with ALLI, 16.8% underwent a single endovascular technique, whereas 83.2% underwent a combination of multiple endovascular techniques. The technicalsuccess, POD, and ALLI-related death rates in the total number of patients were 94.7%, 11.6%, and 4.2%, respectively. A total of 67 patients (75 limbs) and 28 patients (29 limbs) were classified as having native occlusion and graft occlusion (prosthetic, 24 limbs; vein, 5 limbs), respectively. No significant differences in technical success (native occlusion: 92.5% vs. graft occlusion: 100%), POD (14.9% vs. 3.6%), and ALLI-related death (6.0% vs. 0%) were noted between native occlusion and graft occlusion. However, the 30-day AFS rate of native occlusion was significantly lower than that of graft occlusion (75.2% vs. 96.3%, P=0.01). The amputation rate (P=0.03) and AFS rate (P=0.03) of below-knee occlusion were significantly worse for below-knee occlusion patients than for non-below-knee occlusion patients. CONCLUSIONS: EVT using multiple endovascular techniques for ALLI is effective and safe. A combination of multiple endovascular techniques is crucial for successful treatment. However, native occlusion may have a lower AFS rate than graft occlusion, and below-knee occlusion may have a higher risk of amputation than non-below-knee occlusion.

Delayed vascular injury (DVI) with a hemodialysis catheter is a rare but potentially life-threatening complication. However, the appropriate treatment for DVI has not yet been established. A 44-year-old man underwent placement of a hemodialysis catheter via the left internal jugular vein, and the first leukapheresis procedure was performed without complications. However, 3 days after the insertion of the hemodialysis catheter, the patient developed sudden dyspnea. Chest radiographs and contrast-enhanced computed tomography revealed that the catheter tip had migrated and was located outside the left brachiocephalic vein. DVI with catheter migration was diagnosed. To perform safe and reliable hemostasis, we successfully performed transvenous balloon-assisted tract embolization with n-butyl cyanoacrylate and the catheter was removed. To our knowledge, there has been no previous report of the treatment of balloon-assisted tract embolization with n-butyl cyanoacrylate for DVI caused by a hemodialysis catheter. Our treatment approach may be safe and effective for DVI.

BACKGROUND: Balloon-assisted transcatheter arterial embolization (TAE) using n-butyl cyanoacrylate (NBCA) and lipiodol (Lp) mixture is a new endovascular treatment technique for iatrogenic arterial bleeding by groin puncture. It is less invasive compared to surgical repair, and NBCA migration into the circulation can be prevented by temporary balloon occlusion of the parent artery without ultrasound-guidance. This study aimed to report on the technical aspects and evaluate the efficacy and safety of fluoroscopically guided balloon-assisted transcatheter arterial embolization using NBCA for iatrogenic arterial bleeding by groin puncture. MATERIALS AND METHODS: The study included five patients (mean age 54.6 years; 3 male and 2 female) with iatrogenic arterial bleeding by groin puncture. We performed transcatheter arterial embolization using NBCA while occluding the responsible artery with a balloon catheter during the embolization to prevent NBCA migration. Two sheaths were inserted into the common femoral artery. A microcatheter was advanced into the pseudoaneurysm or extravasation via the contralateral sheath. A balloon catheter was advanced into the responsible artery until the balloon portion covered the leakage site via another sheath. After balloon inflation, the NBCA and Lip mixture was slowly injected until the pseudoaneurysm, or the extravasation was filled without touching the balloon. The microcatheter was removed immediately after the filling. We assessed technical success, overall success, and complications. RESULTS: The injured arteries were the external iliac artery (n = 1), the common femoral artery (n = 2), and the proximal portion of the superficial femoral artery (n = 2). NBCA was injected once in four cases and twice in one case where complete hemostasis could not be achieved with one injection. The technical and overall success rate was 100% with no complications, including distal embolization of NBCA. CONCLUSIONS: Balloon-assisted TAE using NBCA is a feasible, effective, and safe treatment for iatrogenic arterial bleeding by groin puncture. It may also be applicable in other arterial bleeding situations where the potential risk of distal embolization can be decreased by applying the balloon-assisted technique.

PURPOSE: To present long-term results obtained with endovascular abdominal aortic aneurysm (AAA) repair (EVAR) using the Zenith AAA endovascular graft from a single institution. MATERIALS AND METHODS: Between 2007 and 2013, 95 consecutive patients (median age 77 years) underwent EVAR using Zenith. Data were prospectively collected and retrospectively analyzed until 2019. Primary outcomes were overall survival, freedom from AAA rupture, and freedom from AAA-related death. Secondary outcomes were freedom from late (> 30 days) re-intervention and surgical conversion, and freedom from aneurysm sac growth (> 5 mm). RESULTS: The initial technical success rate was 96.8%. There were no deaths or intraoperative conversions. Overall survival at 1, 3, 5, and 10 years was 90.8%, 81.7%. 74.3%, and 57.2%, respectively. AAA rupture occurred in one patient (1.1%). Freedom from AAA-related death was 100% during the follow-up period. Freedom from aneurysm sac growth at 1, 3, 5, and 10 years was 98.8%, 86.4%, 76.9%, 53.0%, respectively. Freedom from late re-intervention and open surgical conversion at 1, 3, 5, and 10 years was 98.9%, 88.9%, 86.7, and 57.9%, respectively. CONCLUSION: EVAR with Zenith endografts represents a safe and durable means of AAA repair, and risk of rupture and aneurysm-related death are low.

Objective: To determine if there are changes in the aortic wall before acute aortic dissection (AD) that can be observed on contrast-enhanced computed tomography (CECT). Materials and Methods: Twenty-two patients with AD who underwent CECT before developing AD were retrospectively identified and enrolled as the AD group. Twenty-five consecutive patients who underwent CECT and did not develop AD were enrolled as the control group. In the AD group, the site of entry tear was detected on CECT images; the aortic wall thickness at this site, defined as the dissection-related wall thickness (D-T), was then measured on CECT images acquired before AD. Moreover, the mean thickness of the ascending, thoracic descending, and abdominal aortic walls before AD was defined as the non-dissection-related wall thickness (non-D-T). In the control group, the aortic wall thickness was measured similarly and defined as the control wall thickness (C-T). The D-T, non-D-T, and C-T values were compared using one-way analysis of variance with the Games-Howell pairwise comparison test. Results: The D-T (2.17±0.75 mm) was significantly greater than the non-D-T (1.58±0.22 mm; P<.01) and C-T (1.53±0.15 mm; P<.01). Conclusion: The aortic wall may have become thicker prior to the onset of AD.

Pseudoaneurysm of the superior mesenteric artery (SMA) is rare and associated with the risk of massive fatal hemorrhage and acute mesenteric ischemia. We describe a 43-year-old man with acute pancreatitis who presented with an SMA pseudoaneurysm measuring 13 × 12 cm in diameter. The pseudoaneurysm originated between the first and second jejunal arteries and drained into the mesenteric vein. The SMA trunk between the first and second jejunal arteries was embolized with detachable coils using microballoon assistance. After coil placement, arteriography showed the collateral circulation and no perfusion delay of the distal SMA. This technique was useful for isolation of the SMA pseudoaneurysm.

AIM: To evaluate the relationship between the location of hepatocellular carcinoma (HCC) and the efficacy of transarterial chemoembolization (TACE). METHODS: We evaluated 115 patients (127 nodules), excluding recurrent nodules, treated with TACE between January 2011 and June 2014. TACE efficacy was evaluated according to mRECIST. The HCC location coefficient was calculated as the distance from the central portal portion to the HCC center (mm)/liver diameter (mm) on multiplanar reconstruction images rendered (MPR) to visualize bifurcation of the right and left branches of the portal vein and HCC center. The HCC location coefficient was compared between complete response (CR) and non-CR groups in Child-Pugh grade A and B patients. RESULTS: The median location coefficient of HCC among all nodules, the right lobe, and the medial segment was significantly higher in the CR group than in the non-CR group in the Child-Pugh grade A patients (0.82 vs 0.62, P < 0.001; 0.71 vs 0.59, P < 0.01; 0.81 vs 0.49, P < 0.05, respectively). However, there was no significant difference in the median location coefficient of the HCC in the lateral segment between in the CR and in the non-CR groups (0.67 vs 0.65, P > 0.05). On the other hand, in the Child-Pugh grade B patients, the HCC median location coefficient in each lobe and segment was not significantly different between in the CR and in the non-CR groups. CONCLUSION: Improved TACE efficacy may be obtained for HCC in the peripheral zone of the right lobe and the medial segment in Child-Pugh grade A patients.

一般的に化学療法では薬物最大血中濃度と薬物血中濃度時間曲線下面積の増減が、治療効果に影響を及ぼすとされている。また、抗腫瘍効果の指標としてのIC50(50%の割合で腫瘍が縮小するのに必要な抗がん剤濃度)は、抗がん剤治療を受けた患者では5-10倍に上がるため、既存の抗がん剤治療を受けてもその有効性は非常に厳しいと考えられる。以上のことから、抗腫瘍効果を高めるためには、既存の投与方法に限界があり新しい抗がん剤治療システムを考案する必要性があった。現在行われている化学療法は有害事象の点から投与可能な抗がん剤量はおのずと制限される。閉鎖循環下灌流療法は動注化学療法に体外循環を組み合わせた体外循環動注化学療法であり、薬剤流入路である動脈と、薬剤流出路である静脈を制御することで、標的領域を閉鎖循環下に管理し、体外循環を組み合わせることで標的領域に今まで実現不可能であった高濃度の抗がん剤曝露と抗がん剤の全身漏出の阻止を可能とする新しいドラッグデリバリーシステムである。この論文では今まで20年以上にわたりわれわれが開発・実用化してきた灌流療法システムを紹介する。特に2016年11月に先進医療Bとして承認された閉鎖循環下非均衡抗がん剤灌流療法を主体に論述する。(著者抄録)

代表的な大動脈疾患である大動脈瘤や大動脈解離は,破裂や臓器虚血により生命の危険に陥る可能性のある重篤な疾患であるため,可及的速やかに適切な治療を行うことが求められ,そのためには迅速かつ正確な画像診断が必須である。CTは,比較的簡便で侵襲が低く,かつ短時間で広範囲の領域を客観的に評価でき,さらに緊急検査に対応可能であることから,急性期を含む大動脈疾患における画像診断において中心的な役割を果たしている。その目的はスクリーニングに始まり,血管解剖や破格の評価,瘤,解離,狭窄,閉塞などの診断やその程度に基づく治療適応・治療方針の決定,合併症の評価,治療後のフォローアップなど多岐にわたる。特に近年における多検出器列型CT(multi-detector-row computedtomography;MDCT)の進歩により,より短時間で高精細な画像が取得可能となったことで,その重要性はさらに増しており,大動脈疾患の診療において必要不可欠な検査となっている。一方,MRIは放射線被ばくがないことから,妊娠可能な女性や小児患者に対するフォローアップ画像の際には考慮されるが,検査時間が長く,救急対応が困難であることから急性期には一般的に適応とならない。しかし,高度腎機能障害例においても非造影MRAにより大動脈疾患の評価が可能である。本稿では,代表的な大動脈疾患である大動脈瘤と大動脈解離に対するCT画像診断を中心に,その役割と画像診断のポイントに関して解説する。(著者抄録)
