Retrospective single-arm cohort study of video-assisted thoracic surgery for treatment of idiopathic peripherally located simple type pulmonary arteriovenous malformation in 23 consecutive patients.

Background: Although case reports of video-assisted thoracic surgery (VATS) for pulmonary arteriovenous malformation (PAVM) have been published, studies analyzing more than 10 cases were limited. A retrospective single-arm cohort study was performed to investigate the efficacy of VATS in 23 consecutive patients with idiopathic peripherally located simple type PAVM.

Methods: VATS was performed for wedge resection of 24 PAVMs in 23 patients, which included 4 males and 19 females with an age range of 25 to 80 years (mean: 59.

Selective balloon-occluded transarterial chemoembolization for patients with one or two hepatocellular carcinoma nodules: Retrospective comparison with conventional super-selective TACE.

Aim: Selective balloon-occluded transarterial chemoembolization (B-TACE) enables strong TACE; infusion of more volume of lipiodol emulsion and forceful injection of embolization materials. The aim of this study is to analyze the efficacy of B-TACE for patients with one or two hepatocellular carcinoma (HCC) nodules compared with conventional super-selective TACE using a microcatheter (C-TACE).

Methods: We retrospectively selected patients without previous history of TACE, with one or two HCC nodules, with performance status 0/1, and with liver function of Child-Pugh score A/B.

Diameter of main tumor feeding artery of a hepatocellular carcinoma: Measurement at the entry site into the nodule.

Aim: To measure the diameter of the main tumor feeding artery (TFA) of a hepatocellular carcinoma (HCC) nodule at the entry site into the nodule.

Methods: Fifty-seven HCC nodules in 43 patients were analyzed using a 3-D workstation and picture archiving system (PACS). TFA was defined as an artery connected to a HCC nodule on catheter-assisted multidetector computed tomography angiography (CAMDCTA).

Dense accumulation of lipiodol emulsion in hepatocellular carcinoma nodule during selective balloon-occluded transarterial chemoembolization: measurement of balloon-occluded arterial stump pressure.

Purpose: To reveal the mechanism of dense accumulation of lipiodol emulsion (LE) in hepatocellular carcinoma (HCC) during selective balloon-occluded transarterial chemoembolization (B-TACE).

Methods: Balloon-occluded arterial stump pressure (BOASP) at the embolization portion was measured during selective B-TACE for 43 nodules in 42 patients. Fluoroscopy and digital subtraction angiography were prospectively observed during selective B-TACE to note whether dense LE accumulation in HCC occurred.

Percutaneous ablation of a mesenteric cyst using ethanol: is it feasible?

A huge mesenteric cyst in a 61-year-old female was treated by percutaneous ablation using ethanol. Marked shrinkage was achieved and regrowth was not seen 16 months after ablation. Resection is the standard therapy for mesenteric cysts, but it may be valuable to discuss the feasibility of percutaneous ablation before resection if the lesion wall is smooth and thin, and if solid nodules are not depicted on imaging.

Newly developed application system for CT-guided puncture based on multidetector row CT without CT fluoroscopy.

Purpose: The aim of this article is to describe a preliminary clinical experience with a new multidetector CT (MDCT) system (GuideShot system) for CT-guided intervention.

Materials And Methods: This system enabled simultaneous acquisition and quick display of three axial CT images. Only a single-shot mode was used, with no continuous CT fluoroscopic (CTF) mode.

Successful treatment of mesenteric varices with balloon-occluded retrograde transvenous obliteration via an abdominal wall vein.

Balloon-occluded retrograde transvenous obliteration (BRTO) is an established therapy for gastric varices, but it has been used less frequently for mesenteric varices. This report describes the successful management of mesenteric varices with BRTO performed via an abdominal wall collateral vein detected on contrast medium-enhanced computed tomography.
