Rationale and Objectives Safety and feasibility of contrast-enhanced computed tomography (CECT) with a nanoparticulate contrast agent, ExiTron nano 12000, was evaluated in a rat liver tumor model. Materials and Methods This study employed eighteen 8-week-old male F344 rats. Six rats given tap water for 8 weeks further divided into two: Control gro...

Objective Mapping the long-term prognosis of Budd-Chiari syndrome (BCS) is difficult, as the prognosis is associated with changes in the liver function. The present study evaluated the time course changes in the liver function in a treatment group with percutaneous old balloon angioplasty (POBA) and a non-treatment group using the albumin-bilirubin...
Article
Purpose To develop a deep learning model to generate synthetic, two-dimensional subtraction angiography images free of artifacts from native abdominal angiograms. Materials and Methods In this retrospective study, two-dimensional digital subtraction angiograms (2D-DSA) and native angiograms were consecutively collected from July 2019 to March 2020...

Multidetector row computed tomography (CT) scanners perform dynamic scanning and have a wide scan range. Time-resolved three-dimensional CT (i.e., 4D CT) has recently enabled visualization of flow in neurovascular vessels. We hypothesized that 4D CT technology would be a useful and non-invasive method for visualizing the flow dynamics of the portal...

Objective Patients who undergo Fontan surgery for complex cardiac anomalies are prone to developing liver and gastrointestinal complications. In particular, gastroesophageal varices (GEVs) can occur, but their prevalence is unknown. We aimed to elucidate the occurrence of GEVs and the predicting parameters of GEVs in these patients. Materials and...

Uterine artery embolization (UAE) is a type of noninvasive treatment for symptomatic uterine fibroids. One of the complications of UAE is fibroid expulsion. Here, we report a case of a 45-year-old woman who underwent UAE for an intramural fibroid, which resulted in fibroid expulsion. To the best of our knowledge, there are only few reports of expul...
Article
A 66-year-old man presented with liver cirrhosis due to non-alcoholic steatohepatitis and hyperammonemia. Contrast-enhanced CT showed a dilated and tortuous splenorenal shunt and a large venous aneurysm in the shunt. The venous aneurysm showed gradual enlargement over 10 years and worsening hyperammonemia, so balloon-occluded retrograde transvenous...

Stomal varices are rare and ectopic varices defined as dilated portosystemic collateral veins located in sites other than the gastro-esophageal region. These sometimes cause recurrent bleedings and can be life-threatening. Optimal treatments have yet to be established. We report 3 cases of repetitive bleeding stomal varices in which resolution of b...

Aim Patients who undergo the Fontan procedure for complex congenital heart disease are prone to liver cirrhosis. Liver stiffness (LS) reflects liver fibrosis stage in patients with chronic viral hepatitis; however, its accuracy in predicting liver fibrosis stage in Fontan patients is controversial. We aimed to clarify the correlation between LS and...

Purpose Portal venous system thrombosis is a complication of partial splenic artery embolization, and pre-treatment risk assessment is thus important. The purpose of this study was to identify the risk factors for portal venous system thrombosis after partial splenic artery embolization. Materials and methods We retrospectively analyzed 67 consecu...

Background Colonic varices are rare among ectopic varices. A previous report demonstrated that once bleeding from colonic varices occurs, it can be fatal. Several treatments for colonic varices exist, including surgical, endoscopic, and endovascular treatments; however, management of colonic varices has not been standardized. For colonic varices, m...
Article
PurposeThis study evaluated the survival benefit of a combination therapy with radiofrequency ablation (RFA) and intratumoral cisplatin (ITC) administration for lung tumors by using a rabbit VX2 tumor model.Materials and Methods Experiments were approved by the institutional animal care committee. VX2 tumor suspension was injected into the lungs of...
Article
Objectives To determine the utility of low-dose gelatin sponge particles and 5% ethanolamine oleate iopamidol (EOI) mixture in retrograde transvenous obliteration (GERTO) for gastric varices. Methods Fifty-seven consecutive patients who underwent balloon-occluded retrograde transvenous obliteration (B-RTO) for gastric varices (GV) were divided int...
Article
Purpose Therapeutic predictors derived from the venous pressure before therapy have not been identified for Budd-Chiari syndrome (BCS). The aim of this study was to determine whether or not measuring the distal pressure or pressure gradient was useful for predicting treatment efficacy in BCS. Material and Methods We retrospectively analyzed seven c...
Article
Purpose: To investigate the technical feasibility, safety and clinical outcomes of coil-assisted retrograde transvenous obliteration II (CARTO-II) for gastric varices (GV). Materials and methods: Thirty-six consecutive patients who had undergone CARTO-II between June 2016 and April 2018 were included in the study. In the CARTO procedure, coil em...

Objective Balloon-occluded retrograde transvenous obliteration (B-RTO) for gastric varices (GV) is associated with drawbacks including a postoperative increase in portal pressure and the risk of subsequent worsening of esophageal varices (EV). Selective B-RTO that embolizes only the varices may have the potential to minimize such risks. The aim of...
Article
Purpose To identify the risk factors for local recurrence in hepatocellular carcinoma (HCC) patients treated with transcatheter arterial chemoembolization (TACE) with drug-eluting beads (DEB-TACE). Materials and methods In this retrospective study, 35 patients (27 males, 8 females; median age 73 years) with 116 tumors (median size 14 mm) treated w...
Article
Background Sinusoidal obstruction syndrome (SOS) is a significant, potentially life-threatening complication of allogeneic hematopoietic cell transplantation (allo-HCT). In particular, severe SOS frequently causes multiple organ failure and results in poor prognosis. Although early and accurate diagnosis of SOS is vital to intervene early and impro...

Objectives: The purpose of this study was to retrospectively evaluate the effectiveness of the model for end-stage liver disease (MELD) score compared with the Child-Pugh classification in patients who received 3-dimensional conformal radiotherapy (3D-CRT) for hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) by analyzing tox...
Article
Purpose: To investigate predictive factors and cutoff value of transient elastography (TE) measurements for assessing improvement in liver function after balloon-occluded retrograde transvenous obliteration (BRTO) for gastric varices (GV). Materials and methods: Retrospective analysis was performed of 50 consecutive patients followed for > 3 mon...
Article
Background: Focal stenosis or occlusion of the infrarenal aorta is rare, and treatment is usually conventional bypass or endarterectomy. However, endovascular treatment has advanced in recent years. The purpose of this retrospective study is to report the results of primary stenting for focal infrarenal aortic occlusive disease and clarify the use...

To evaluate the feasibility of gastric variceal (GV) volumetry using computed tomography (CT) images taken before balloon-occluded retrograde transvenous obliteration (B-RTO) and to assess its correlation with the actual amount of 5% ethanolamine oleate and iodinated contrast medium (EOI) injected in B-RTO. Forty-seven consecutive patients with GV...
Article
Balloon-occluded retrograde transvenous obliteration (B-RTO) has shown great potential in controlling acute gastric variceal hemorrhage, although rebleeding related to the procedure may occur in a small percentage of patients. The purpose of this study was to identify risk factors of perioperative rebleeding and prognostic factors of postoperative...
