Isolated spontaneous dissection of the superior mesenteric artery is a very rare condition. Endovascular stent placement has been proposed recently for selected cases, which has led to some good clinical results. We report a case of spontaneous dissection of the superior mesenteric artery spreading to the origin of a right ...

CONTEXT: It is important to recognize arterial variants in the preoperative planning of extended pancreatic resections. The absence of surgical confirmation of radiological data is a limitation of the majority of angiographic or CT-angiographic studies of celiac and mesenteric arterial anatomy. OBJECTIVE: The purpose of this study was to test ...

Visceral artery aneurysms (VAA), although uncommon, are increasingly being detected. We describe a case of spontaneous retroperitoneal hemorrhage from a ruptured IMA aneurysm associated with stenosis of the superior mesenteric artery (SMA) and celiac trunk, successfully treated with surgery. A 65-year-old man presented with abdominal pain and hypovolemic shock. Abdominal ...

Antithrombin is a potent inhibitor of the coagulation cascade exerting its primary effects on activated factors X, IX and II. It is the mechanism by which heparin and low-molecular weight heparin cause anti-coagulation. Deficiency of antithrombin presents as a hypercoagulable state, and may result in unexplained deep venous thrombosis, arterial ...

In patients with acute mesenteric ischemia by occlusive thrombo-embolism, the superior mesenteric artery (SMA) is more affected than the inferior mesenteric artery (IMA). This study investigated postmortem mesenteric arteries from aged subjects (n=21). Four atherosclerotic stages were defined by signs of degeneration and inflammation in sections stained with Elastica-van-Gieson and ...

Superior mesenteric artery (SMA) aneurysms represent a minority of visceral aneurysms but may result in lethal complications if left untreated. Options for treatment include aneurysmorraphy, bypass, ligation, or embolization. Here we present a case of a man with a history of celiac graft thrombosis who presents with a recurrent symptomatic ...

Fibromuscular dysplasia or fibromuscular hyperplasia is a rare non-atherosclerotic and non-inflammatory vascular disease that primarily involves medium-size and small arteries, most commonly the renal and carotid arteries, and less frequently the vertebral, iliac, subclavian or visceral arteries (mesenteric, hepatic, splenic). Antiphospholipid syndrome is one of the most commonly acquired hypercoagulable ...

The study goals were to demonstrate the superior laryngeal artery in detail with angiograms and to understand its vasculature three-dimensionally. Three fresh cadavers were totally injected with lead oxide-gelatin mixture. The larynx with the surrounding tissue was resected and radiographed stereoscopically with soft X ray system. We get informed consent ...

A case of urinary vessel calcification was detected incidentally in pelvic cavity of a 59-year-old man by computed tomography. The silver reticulin, actin, and hematoxylin and eosin stains were applied to diagnose the feature of vessel and confirmed that the vessel was the vesical artery. To our knowledge, this is ...

With light and scanning electron microscopy of vascular corrosion casts, we have observed in Urobatis jamaicensis that the fourth epibranchial arteries do not merge completely with the dorsal aorta. Instead they form a brief anastomosis with a short vessel projecting ventrally from the dorsal aorta and maintain their integrity as ...

Islet transplantation is emerging as a treatment option for selected patients with type 1 diabetes. The limited human islet supply from cadavers and poor islet yield and quality remain substantial impediments to progress in the field. Use of porcine islets holds great promise for large-scale application of islet transplantation. Consistent ...

Bladder haemorrhage is common and sometimes life-threatening. Management options include bladder irrigation and supportive transfusion, intravesical instillation, endourological intervention, and surgical intervention which has poor success and high morbidity rates. Percutaneous arterial embolisation offers another minimally invasive option. We report two patients with severe haemorrhagic cystitis treated with superselective embolisation ...

Abdominal angina followed by an active vascular intervention constitutes an infrequent sequence of events. The limited experience in the active management of this, potentially lethal, condition prompted us to present the case of a 54 year old man with an exceedingly rare etiology of mesenteric ischemia. The underlying cause was ...
