title: Transcatheter embolization for acute lower gastrointestinal hemorrhage.
abstract: OBJECTIVE
  The authors review their experience using transcatheter embolization in the treatment of acute lower gastrointestinal hemorrhage.
  
  
  METHODS
  A retrospective review was conducted on 17 patients who underwent superselective transcatheter embolization for an acute lower gastrointestinal hemorrhage. All 17 patients were followed clinically 4 days to 60 months (mean, 18.5 months) after embolization for the presence of ischemia or for recurrent bleeding. In addition, 12 of 17 patients were examined 1 day to 12 months (mean, 38.8 months) after embolization by means of colonoscopy or by pathologic review.
  
  
  RESULTS
  Transcatheter embolization achieved immediate hemostasis in 15 of 17 patients (88%) and was the definitive treatment in 76%. The other two patients underwent successful surgical resections after incomplete hemostasis of cecal lesions. Two patients of the 15, with initially successful embolizations, had recurrent hemorrhage within 30 days; both underwent further embolization with one failure. No intestinal infarction or stricture developed in the 15 patients who underwent successful embolization.
  
  
  CONCLUSIONS
  The authors' experience supports the role of transcatheter embolization as a primary means of therapy for patients with an acute lower gastrointestinal hemorrhage. Their data further supports growing evidence that superselective embolization may be most efficacious in reducing complication rates.
