Microscopic polyangiitis is an uncommon systemic vasculitis of varying severity that is associated with myeloperoxidase (MPO) and perinuclear antineutrophil cytoplasmic (p-ANCA) antibodies. The most commonly affected organs are the lungs and kidneys. We report on a very unusual case of microscopic polyangiitis presenting with severe mesenteric ischemia in addition to diffuse alveolar hemorrhage...

CONTEXT Large visceral artery occlusion (LVAO) could underlie right-side colon ischemia (RSCI) but is little known. OBJECTIVE To assess patients with RSCI through long-term follow-up, including features and management of LVAO. MAIN OUTCOME MEASURES Mesenteric ischemia and mortality. DESIGN Retrospective observational study in an integrated health care system. RESULTS Of 49 patients (30 ...

BACKGROUND Non-occlusive mesenteric ischemia is not uncommon in chronic hemodialysis patients and is the major cause of an acute abdomen in this population. Intensive ultrafiltration and intradialytic hypotension are usually the precipitation factors. A definite diagnosis is usually late and associated with high mortality. We present a rare case of a patient who developed abdominal symptoms dur...

INTRODUCTION There is no valid and reliable diagnostic test for early diagnosis of acute mesenteric ischemia (AMI). The aim of this study was to measure the plasma levels of diamine oxidase (DAO) and citrulline in AMI to gain insight into its early diagnosis. MATERIAL AND METHODS A total of 21 Wistar albino rats were divided into three groups, that is, control group, short-term ischemia group...

Acute mesenteric ischemia representbi 0.1% to 0.01 % of al1 hospitalized patients. Its peak incidence is found bcîween the sixth and seventh decade and it is associated with a high mortality rate (estimated between 60 and 80% according to the litterature). The obsemed clinical presentations are not often clearly suggestive of mesenteric kchemia therefore its possibility must always bc kept in m...

BACKGROUND Thrombotic events, arterial or venous in origin, still remain a source of substantial morbidity and mortality in cancer patients. The propensity for their development in oncology patients is partially a consequence of the disease itself and partially a result of our attempts to treat it. One of the rarest and deadliest thromboembolic complications is arterial mesenteric ischemia. The...

BACKGROUND Mesenteric venous thrombosis is an uncommon but often lethal form of intestinal ischemia. METHODS We reviewed pertinent literature on mesenteric venous thrombosis using MEDLINE search. RESULTS We found that previous abdominal surgery and hypercoagulable states are the most common conditions associated with mesenteric venous thrombosis. The symptoms and signs related to mesenteric...

Background Vascular calcifications have been identified as predictors of mortality in several cardiovascular diseases but not investigated context acute mesenteric ischemia. The aim this study was to investigate the impact vascular patients with Methods Patients admitted for an ischemia were retrospectively included. presence visceral aorta, celiac trunk, superior artery, and ...

Superior mesenteric artery embolism or thrombosis and nonocclusive ischemia are the most frequent causes of mesenteric ischemia. Symptoms out of proportion to the physical findings, leucocytosis, and metabolic acidosis suggest the diagnosis. A high index of suspicion, aggressive resuscitation and correction of metabolic derangements, early angiography, and operative intervention are necessary i...
