Mesenteric artery embolization by an unsuspected aortic tumor: diagnostic evaluation and operative management.

Malignant tumor embolus recovered at the time of superior mesenteric artery embolectomy is an uncommon experience. A report of such a case is presented and the literature is reviewed. In this clinical setting, guidelines for further diagnostic evaluation are not well defined. We suggest an algorithm for the evaluation and management of these patients. In the near future, use of intraoperative angioscopy and the intravascular laser to eradicate the tumor may represent the optimal method of treatment.
