Acute mesenteric ischemia

Abstrakt

Acute mesenteric ischemia (AMI) is a medical and surgical emergency. It remains a challenging diagnosis with a high mortality rate, and requires early recognition and prompt treatment before the onset of bowel infarction. Acute mesenteric insufficiency can be due to occlusive or non-occlusive obstruction of arterial or venous blood supply. Symptoms vary from the insidious onset of vague generalized abdominal pain to the sudden onset of diffuse, severe constant pain. Clinical suspicion of AMI necessitates early radiologie evaluation (computed tomographic (CT) angiography, conventional angiography) or exploratory surgery in patients with peritoneal signs. The purpose of treatment of patients with acute mesenteric ischemia is to restore intestinal blood supply as quickly as possible. Treatment options include resuscitation, mesenteric revascularization and resection of necrotic bowel.
