SELECTIVE SUPERIOR MESENTERY ARTERIOGRAPHY AND GUIDE-WIRE AS AN INTRAOPERATIVE LOCATING MARK IN SMALL-INTESTINE RESECTION FOR ARTERIOVENOUS-MALFORMATIONS

Objective To investigate the effectiveness of selective superior mesen tery arteriography and a guide wire as an intraoperative locating mark on diagnosing, locating the bleeding sites in the small intestines ca used by arteriovenous malformations (AVMs). Methods The selective supe rior mesentery arteriography was done in seven patients with AVMs of t he intestines, and a segment of guide wire was placed simultaneously a s a locating mark. Results All the resected intestines were marked by sutures for pathological examination and confirmed as AVMs of the smal l intestines. The patients were followed up for an average of 25 month s (17-35 months). During this period, all patients had no recurrence o f hemorrhage. Conclusion The selective superior mesentery arteriograph y and placement of a guide wire as an intraoperative locating mark in AVMs of the intestines can help surgeons successfully in finding and r esecting the lesions without complications. It is a new method and has a perspective to be widely spread.
