A 55-year-old man underwent pancreaticoduodenectomy for bile duct carcinoma in March 2009. The patient developed anastomotic leakage and had a short episode of hemorrhage from the drainage tubes with spontaneous disappearance. CT and upper endoscopy did not reveal the source of bleeding. A massive life-threatening hemorrhage occurred on the 18th postsurgical day. Emergency angiography showed a ...

The technique with a wing microcatheter system and the pathologic aspects of 11 cerebral arteriovenous malformations (AVMs) surgically resected after embolization with polylene threads are reported. Embolization was performed once in eight patients and twice in three patients. Resected AVMs were submitted both to routine hematoxylineosin examination and to immunohistochemical workup in order to...

OBJECTIVE To evaluate the clinical outcome of coil embolization for unruptured intracranial aneurysm (UIA) with oculomotor nerve palsy (ONP) compared with surgical clipping. METHODS A total of 19 patients presented with ONP caused by UIAs between Jan 2004 and June 2008. Ten patients underwent coil embolization and nine patients surgical clipping. The following parameters were retrospectively ...

Purpose: To determine if there were differences in quality of life (QOL) within the first year following EVAR for patients undergoing internal iliac embolization depending on the type of device used. Methods: Patients who underwent endovascular AAA repair were identified using a Vascular surgery database at a tertiary care center from 2002-2008. The Radiology Information System and Image Viewer...

PURPOSE To evaluate the acute and midterm effectiveness of a novel vascular occlusion device for embolization of the internal iliac artery (IIA) before endovascular repair of aortoiliac aneurysms. MATERIALS AND METHODS Between March 2005 and April 2006, nine men (mean age, 75 years +/- 5; range, 66-83 y) with aortoiliac aneurysms underwent bifurcated endovascular stent-graft procedures. All t...

OBJECTIVE To evaluate the use of a new spherical particle of polyvinyl alcohol and polyvinyl acetate (PVA-PVAc) for uterine artery embolization in patients with myoma with surgical indication. METHODS twelve patients underwent uterine myoma embolization with PVA-PVAc particles. Three to nine months later, they were submitted to laparotomy with myomectomy. We analyzed the following parameters:...

Aneurysm volume/virtual column volume (AV/CV) ratio, calculated from measurements derived from reconstructed images based on rotational three-dimensional digital subtraction angiography (3D-DSA), was investigated as a predictor of the success of intraaneurysmal embolization in 20 unruptured wide-necked internal carotid artery aneurysms treated by Guglielmi detachable coils. AV and neck area wer...

BACKGROUND Portal vein embolization is an accepted procedure that provides hypertrophy of the future remnant liver in order to reduce post-hepatectomy complications. AIM To present a series submitted to portal vein embolization using an adapted hysterosalpingography catheter via transileocolic route. METHODS Were performed right portal branch embolization in 19 patients using hysterosalping...

Although early device embolization is a well-known complication of percutaneous atrial septal defect (ASD) closure, late device embolization is rarely encountered and information about management of it are very limited. Herein, we reported a case of late ASD device embolization into the abdominal aorta at the level of the superior mesenteric artery, 8 months after percutaneous closure.

Type II endoleak (T2E) leading to aneurysm sac enlargement is one of the challenging complications associated with endovascular aneurysm repair. Recent guidelines recommend embolization of T2E associated with aneurysmal sac enlargement. Various percutaneous and endovascular techniques have been reported for embolization of T2E. We report a novel technique for T2E embolization combining laparosc...
