Introduction Non-occlusive mesenteric ischemia (NOMI) is an acute mesenteric circulatory disorder that, in contrast to mesenteric arterial occlusion induced by blockage of blood flow by emboli and thrombi, is not caused by organic occlusion of blood vessels. 1 Good outcomes in NOMI are observed with early recognition and treatment. 1-2 The early symptoms and characteristics of NOMI, however, ar...

Acute mesenteric ischemia is a rare cause of abdominal pain with a very high mortality rate. Vague presentation and often misleading clinical findings make the diagnosis elusive. Here, a unique case of complete superior mesenteric artery occlusion further complicated by basilar artery occlusion is illustrated.

Prompt diagnosis of acute mesenteric ischemia is a dilemma which is unfortunately generally made at the irreversible phase of intestinal damage. Besides conventional diagnostic imaging modalities contrast enhanced multidetector computed tomography angiography enables fast and detailed evaluation of the mesenteric circulation and abdominal viscera which provides accurate and rapid diagnosis in t...

Tel: +90 212 414 20 00 e-mail (e-posta): [email protected] BACKGROUND Mesenteric vein thrombosis occurs rarely and is responsible for approximately 5-15% of all cases of acute mesenteric ischemia.

Symptomatic occlusion of the superior mesenteric artery can be treated by open repair, hybrid procedure, or endovascular revascularization. In most cases, endovascular procedures are done by the antegrade approach. We report a case of a 67-year-old woman who presented with acute-on-chronic mesenteric ischemia successfully treated by retrograde endovascular recanalization of an occluded common h...

Ischemia of the intestine may manifest with different clinical features, each one requiring a specific diag­ nosis and treatment approach. Early identification and treatment of acute mesenteric ischemia is cru­ cial to improve prognosis. For that purpose, early angiography followed by surgery or a direct laparo­ tomy in critically ill patients is warranted. Embolec­ tomy and bowel resection for...

Mesenteric ischemia is caused by blood flow that is insufficient to meet the metabolic demands of the visceral organs. The severity of ischemia and the type of organ involved depend on the affected vessel and the extent of collateral-vessel blood flow. Despite advances in the techniques used to treat problems in the mesenteric circulation, the most critical factor influencing outcomes in patien...

BACKGROUND It is unknown if cardiac ischemia has any deleterious effect on the contractile properties of nonischemic, peripheral vascular beds. Thus, the objective of the present study was to determine whether acute myocardial ischemia results in peripheral vascular dysfunction. METHODS AND RESULTS This study characterized force maintenance and the sensitivity to acetylcholine (ACh)-mediated ...

Question: Is biphasic computed tomography (CT) with mesenteric CT angiography effective in diagnosing acute mesenteric ischemia (AMI)? Design: Prospective cohort study. Setting: Two tertiary care centres in Canada. Patients: Sixty-two patients had clinically suspected AMI, with a finding of abdominal pain and at least 1 of the following symptoms: pain out of proportion to clinical findings; bio...
