Intravenous drug abuse is an increasing social and health problem. Repeated injuries to the veins, injection of some types of insoluble substances, and needle sharing habits result in various complications. Increasing incidence of major vascular complications has been reported worldwide. The objective of this study was to determine the epidemiology of vascular lesions in drug abusers. Medical r...

A 29-year-old female wasadmitted to the hospital because of increasing exertional dyspnea, chest oppressive feeling and palpitation. Lung per fusion scan, pulmonary angiography, and venography of the lower extremities revealed multiple pulmonary embolism and a right popliteal venous aneurysm as the probable source of emboli. B-mode/Doppler echography and magnetic resonance imaging were useful f...

Background: Venous aneurysms are rare, but they can affect all the veins in body, including extremities, head and neck, abdomen; among these, popliteal venous (PVAs) most frequent best studied of aneurysms. While superficial usually visible rarely associated with major complications, deep not often detected at physical examination more commonly complications such as thrombosis pulmonary embolis...

Portal vein aneurysm is a relatively uncommon entity. It is often an incidental, asymptomatic nding. With the increasing availability of advanced imaging modalities like Doppler ultrasound, computed tomography and magnetic resonance imaging, portal venous system aneurysms are being increasingly reported. We report two cases of intra hepatic portal vein aneurysm diagnosed incidentally on ultra-...

INTRODUCTION The potential complications of an abdominal aortic aneurysm include rupture, compression of surrounding structures, thrombo-embolic events and fistula. The most common site of arterio-venous fistula is the inferior vena cava. Fistula involving a renal vein is particularly uncommon. CASE PRESENTATION This report describes a 54-year-old Caucasian woman who was admitted to the emerg...

BACKGROUND AND PURPOSE In this study, we present our experience with 11 patients with ruptured cavernous sinus aneurysms causing carotid cavernous fistulas (CCFs), to assess the incidence of ruptured cavernous sinus aneurysms causing CCFs and evaluate clinical presentations, treatments, and outcomes. PATIENTS AND METHODS During a 10-year period, 10 of 689 (1.5%) endovascular-treated ruptured ...

INTRODUCTION Aneurysm is a localized dilatation of an artery of at least 1.5 times the normal diameter that occurs when part of an artery wall weakens or is injured, allowing it to widen abnormally. In practice, an arterial aneurysm is more common in comparison to a venous aneurysm. Because of the rare incidence of venous aneurysms, treatment guidelines are not clearly established and thus trea...

in order to create an effective arteriovenous fistula (avf) in patients with sustained chronic renal failure (crf), surgeons need to become familiar with various anatomical variations of venous structures in the operating field. because of variety and different types of cubital venous anatomies, there is more than a 90% possibility of creating suitable avfs in the cubital fossa , but in the wri...
