Outcomes of embolization procedures for type II endoleaks following endovascular abdominal aortic repair.

Objective: The objective of this study was to investigate the mid-term outcomes of embolization procedures for type II endoleak after endovascular abdominal aortic repair, and clarify the risk factors for aneurysm enlargement after embolization procedures.

Methods: This was a retrospective multicenter registry study enrolling patients who underwent embolization procedures for type II endoleaks after EVAR from January 2012 to December 2018 at 19 Japanese centers. The primary end point was the rate of freedom from aneurysm enlargement, more than 5 mm in the aortic maximum diameter, after an embolization procedure.

A 2-Stage Surgical and Endovascular Treatment of Rare Multiple Aneurysms of Pancreatic Arteries.

Aneurysms of pancreatic arteries (PAs) are often found incidentally during evaluation of other abdominal pathology. Aneurysms involving multiple PAs are rarely reported in the literature. In case reports of PA aneurysm, inferior pancreaticoduodenal artery is the usual site of aneurysm occurrence.

Efficacy of venous sac embolization for pulmonary arteriovenous malformations: comparison with feeding artery embolization.

Purpose: To examine the efficacy of venous sac embolization (VSE) in comparison with transcatheter feeding artery embolization (FAE) for treatment of pulmonary arteriovenous malformations (PAVMs).

Materials And Methods: From 1989-2009, 21 patients underwent embolization of 37 PAVMs. Safety and long-term efficacy of VSE were evaluated retrospectively and compared with FAE.

Coil embolization of a celiac artery aneurysm using the neck remodeling technique.

Aneurysms of the celiac trunk are rare. Untreated lesions enlarge progressively and may rupture spontaneously. We report the case of a 56-year-old man whose wide neck celiac aneurysm was successfully packed with coils with preservation of the native arterial circulation by percutaneous transcatheter embolization using the neck remodeling technique.

Embolization of hepatic arteriovenous shunt with absolute ethanol in a patient with hepatocellular carcinoma.

We report a 76-year-old man who had hepatocellular carcinoma (HCC) with arteriovenous shunting (AVS). Transcatheter chemoembolization (TACE) was selected as treatment because of poor pulmonary function. To prevent pulmonary embolism caused by the flow of embolic materials through the AVS, we performed embolization of the AVS with absolute ethanol under flow control by balloon catheters.

Successful portal-systemic shunt occlusion of a direct shunt between the inferior mesenteric vein and inferior vena cava with balloon-occluded retrograde transvenous obliteration following recanalization after placing a covered stent in the portal and superior mesenteric veins.

Extrahepatic portal-systemic shunts cause portal-systemic encephalopathy. Direct communication between the inferior mesenteric vein (IMV) and the inferior vena cava (IVC) is a relatively rare pathway among the variety of portal-systemic shunts. This report describes a case of successful occlusion of an IMV-IVC shunt.

Gas embolism caused by portal vein gas: case report and literature review.

Introduction: We describe a case of pulmonary gas embolism caused by portal vein gas (PVG) observed using echocardiography. Echography revealed gas flowing through the hepatic vein, inferior vena cava, right atrium, and right ventricle, as well as pulmonary hypertension. The patient was diagnosed as having pulmonary gas embolism caused by PVG.
