title: Selective superior mesentery arteriography and guide wire as an intraoperative locating mark in small intestine resection for arteriovenous malformations.
abstract: OBJECTIVE
  To investigate the effectiveness of selective superior mesentery arteriography and a guide wire as an intraoperative locating mark on diagnosing, locating the bleeding sites in the small intestines caused by arteriovenous malformations (AVMs).
  
  
  METHODS
  The selective superior mesentery arteriography was done in seven patients with AVMs of the intestines, and a segment of guide wire was placed simultaneously as a locating mark.
  
  
  RESULTS
  All the resected intestines were marked by sutures for pathological examination and confirmed as AVMs of the small intestines. The patients were followed up for an average of 25 months (17-35 months). During this period, all patients had no recurrence of hemorrhage.
  
  
  CONCLUSIONS
  The selective superior mesentery arteriography and placement of a guide wire as an intraoperative locating mark in AVMs of the intestines can help surgeons successfully in finding and resecting the lesions without complications. It is a new method and has a perspective to be widely spread.
