Superselective Embolization for Lower Gastrointestinal Hemorrhage: An Institutional Review Over 7 Years

Abstract

The use of superselective mesenteric embolization for the treatment of lower GI bleeding is highly successful and relatively safe-97% technical success and 3% postembolization ischemia in our series. In 63% of cases it is definitive without any further intervention. Postembolization ischemia and surgery may be associated with a higher risk of anastomotic leak. Greater vigilance must be adopted in treating patients who have active hemorrhage from the small bowel and in those with a hematocrit </=20.0%.
