Diagnosis and management of intestinal ischaemic disorders

摘要

Acute intestinal ischaemia and infarction can result from impaired blood flow within the mesenteric arterial or venous systems and are most often caused by thrombotic or embolic disease Chronic mesenteric ischaemia is often characterised by postprandial abdominal pain, sitophobia, and weight loss Acute, subacute, or chronic mesenteric venous thrombosis can be the result of" primary hypercoagulable disorders or can be secondary to drugs, portal hypertension, paraneoplastic states, or inflammatory abdominal processes Ischaemic colitis results from conditions causing colonic hypoperfusion and embolic or thrombotic occlusion of the vascular supply of the colon Computed tomography angiography and magnetic resonance imaging have developed into highly accurate and non-invasive methods of diagnosing mesenteric ischaemia Surgical revascularisation remains the treatment of choice for mesenteric ischaemia, but thrombolytic medical treatment and vascular interventional radiological techniques have a growing role.
