CONTEXT Mucinous cystic tumors occur almost exclusively in middle-aged women and in the body or tail of the pancreas. Mucinous cystadenocarcinoma, a malignant sub-type of mucinous cystic tumors, in the head of the pancreas and in a middle-aged man is extraordinary, and the prognosis and proper management of mucinous cystadenocarcinoma has not been well documented. CASE REPORT A 52-year-old ma...

The endovascular treatment of spontaneous dural cavernous sinus fistula (DAVF) can be accomplished by arterial approach, just with symptoms relief, or by numerous venous approaches through the inferior petrosal sinus, ophthalmic vein, anterior or posterior intercavernous sinus and facial vein. Our case suggests the approach to the cavernous sinus via the foramen ovale and emissary veins punctur...

OBJECTIVE To evaluate predictors of survival time in dogs undergoing adrenalectomy and identify risk factors associated with adrenal gland tumor metastasis and vein thrombosis. DESIGN Retrospective case series. ANIMALS 52 dogs with primary adrenal gland tumors. PROCEDURES Medical records were reviewed. Signalment, tumor features, and information from surgical procedures were evaluated to ...

OBJECTIVE Vein graft remodeling and neointimal hyperplasia involve inflammation, graft-intrinsic cells, and recruitment of vascular progenitor cells. We sought to examine if the inflammatory cytokine tumor necrosis factor (TNF) affects vein graft remodeling via its p55 TNF receptor-1 (p55). METHODS AND RESULTS Inferior vena cava-to-carotid artery interposition grafting was performed between p...

The aim of this study was to assess the computed tomography angiography (CTA) manifestations of collateral circulations in patients with Budd-Chiari syndrome (BCS). Eighty patients with BCS were examined by CT scan. Using the CTA images of the relevant blood vessels, including the affected hepatic veins (HVs) and inferior venae cavae (IVCs), the collateral circulations were reconstructed. In ad...

BACKGROUND Patients who have Stanford type A aortic dissection with impaired coronary arteries or who have aneurysms from the ascending aorta to the aortic arch with coronary artery disease need coronary artery bypass grafting (CABG) with tube graft replacement of the ascending aorta simultaneously. When vein grafts are used for CABG in these patients, the proximal anastomoses of vein grafts ar...

Smooth muscle cell (SMC) accumulation in the inner layer of the vessel wall is a key event in the pathogenesis of atherosclerosis in vein grafts, but the origin of the cells in these lesions has yet to be shown. Herein, we use animal models of vein grafts in transgenic mice to clearly identify the sources of SMCs in atherosclerosis. Vena cava segments were isografted to carotid arteries between...

We have characterized the blistered (bs) locus phenotypically, genetically and developmentally using a set of new bs alleles. Mutant defects range from wings with ectopic veins and intervein blisters to completely ballooned wings where the distinction between vein and intervein is lost. Mosaic analyses show that severe bs alleles behave largely autonomously; homozygous patches having vein-like ...

postoperative portal vein thrombosis is a rare complication which occurs most often after hepatobiliary surgery.to date, few cases following laparoscopic cho lecystectomy have been reported. in this paper we present a case of portal vein thrombosis diagnosed with abdominal ct scan on the seventh day following laparoscopic cholecystectomy.the patient was administered therapeutic intravenous hepa...
