Selective arterial embolization for the control of lower gastrointestinal bleeding.
American Journal of Surgery 1997 July
BACKGROUND: Transcatheter embolization is accepted as a safe method for treating acute bleeding from the upper gastrointestinal (GI) tract. Hesitancy persists using this technique below the ligament of Treitz, based on the belief that the risk of intestinal infarction is unacceptably high, despite mounting clinical evidence to the contrary.
METHODS: A series of 17 consecutive patients with angiographically demonstrated small intestinal or colonic bleeding was retrospectively reviewed. The success and complication rate of subselective embolization was assessed.
RESULTS: Bleeding was stopped in 13 of 14 patients (93%) in whom embolization was possible, and in 13 of 17 patients (76%) where there was an intention to treat. Sufficiently selective catheterization to permit embolization could not be achieved in 3 patients. No clinically apparent bowel infarctions were caused.
CONCLUSION: Subselective embolization is a safe treatment option for lower GI bleeding, suitable for many patients and effective in most. Careful technique and a readiness to abandon embolization when a suitable catheter position cannot be achieved are important.
