Interventional embolectomy for acute superior mesenteric artery embolism

Objective: To evaluate the effects of percutaneous embolectomy for treatment of acute superior mesenteric artery embolism. Methods: 34 cases (atrial fibrillation 14 cases; left atrium myxoma 2 cases; SMA thrombosis 15 cases and chronic mesenteric ischemia 3 cases) of acute mesenteric artery embolism were treated with percutaneous embolectomy using long sheath aspiration method and/or thrombolysis via catheterization of the SMA. Results: Successful recanalizations were achieved in all of the 34 superior mesenteric arterial embolism including recovery in 31 cases, laparotomy for 2 cases, and 1 died within 24 hours. Conclusions: Percutaneous embolectomy using long sheath aspiration is a simple and effective method for treatment of acute superior mesenteric artery embolism. A correct pathogenetic diagnosis is the key to improve the curative effect and avoid the severe complication. (authors)
