BACKGROUND: Chronic occlusive mesenteric ischaemia can be treated surgically or endovascularly. Endovascular techniques as elsewhere in the vascular tree are limited by restenosis. The aim of this study was to determine if duplex ultrasound proven restenosis correlates with recurrence of symptoms. METHODS: Our study looks at successful percutaneous revascularization of ...

Adolescent idiopathic scoliosis is defined as a lateral curvature of the spine that can occur in any region of the spinal column. For curves that require surgical correction, spinal fusion is the surgical treatment, and superior mesenteric artery syndrome is a possible complication. Risk factors for superior mesenteric artery syndrome ...

OBJECTIVE: MDCT is performed as first imaging examination for patients with acute abdomen in most Emergency Departments. Clinical suspicion of ischemic colitis and infarction is related to specific findings, however, differential diagnosis as well as the staging for a confirmed ischemic affection may be critical. The individual signs from ischemia ...

Acute thrombo-embolic occlusion of the superior mesenteric artery (SMA) is potentially fatal vascular emergency that requires rapid restoration of mesenteric blood flow as well as early diagnosis. Selective thrombolysis has been employed for this life-threatening event. Although failed thrombolysis is a well known phenomenon, which is directly connected with bowel ...

Polyarteritis nodosa (PAN) is a necrotizing angiitis that predominantly affects small- and medium-sized arteries. Polyarteritis nodosa occurs rarely during childhood. Boys and girls seem to be equally affected, with a peak at the age of 10 years. Rarely, severe and fatal gastrointestinal involvement is seen in PAN. Here, we report ...

Aneurysms of the pancreaticoduodenal arteries (PDA) are rare, accounting for <2% of all visceral aneurysms. An association with celiac artery stenosis has been reported. Many present with rupture, and a high mortality can be expected. Treatment is therefore challenging. Arterial ligation, anuerysmectomy, or bypass has been the mainstay of treatment. ...

The middle mesenteric artery is a rare anomalous mesenteric vessel that may supply variable segments of the colon. Occlusion of this artery during endovascular aortic aneurysm repair may bear a significant risk of bowel ischemia. We report the successful interventional treatment of a patient with a 5.3 cm infrarenal abdominal ...

Enterocolic lymphocytic phlebitis is a rare cause of segmental ischemic enterocolitis. This artery-sparing transmural vasculitis is classically a circumferential phlebitis with perivenular lymphocyte cuffing and thrombi in the absence of systemic manifestations. Myointimal hyperplasia may represent a chronic phase of enterocolic lymphocytic phlebitis. Subclinical or early stage enterocolic lymphocytic phlebitis ...

Idiopathic myointimal hyperplasia of mesenteric veins (IMHMV) is a rare and poorly understood disease that occurs in the rectosigmoid colon of predominantly young, previously healthy, male patients. This disease is often confused with chronic idiopathic inflammatory bowel disease clinically, and pathologists may miss the diagnosis unless elastin stains are performed ...

The mechanosensitive nonselective cation channel (NSC(MS)) is a key player in vascular myogenic contraction. The functional channel density and pressure sensitivity of NSC(MS) in vascular myocytes were compared between pulmonary and systemic arteries (coronary, mesenteric and cerebral arteries) in the rabbit. In cell-attached condition, a negative pressure via patch pipettes ...

A case of gastrointestinal hemorrhage, associated with abdominal pain, in an 8-year-old child because of an arterial malformation of duodenum is reported. Selective arteriography showed the presence of an aneurismatic lesion of superior pancreaticoduodenal artery. The leakage of the vascular lesion during examination permitted the embolization by microcoils and cyanoacrylate ...

Thromboangiitis obliterans (TAO) is an inflammatory, nonocclusive, and nonatherosclerotic vascular disease. It commonly affects arteries, veins, and surrounding neural elements and is directly related to smoking. Although distal vessels of lower and upper extremities are the most commonly involved, other vessels such as intestinal arteries can be rarely affected. The ...
