Abstract
The study goal was to evaluate the efficacy, safety, and clinical outcome of transarterial embolization for postoperative hemorrhage after abdominal surgery. Thirty-three patients were referred for angiography because of gastrointestinal or intra-abdominal bleeding after abdominal surgery. Urgent angiography and transarterial embolization was performed in all 33 patients. The clinical and angiographic features were retrospectively reviewed. Angiography revealed a discrete bleeding focus in 26 (79%) of 33 patients. Transarterial embolization was technically successful in 24 (92%) of 26 patients with a discrete bleeding focus. Rebleeding occurred in four (17%) of 24 patients. They were successfully managed with repeat embolization. There was no procedure-related complication during follow-up period. Angiography has a high detection rate of bleeding site in patients with postoperative hemorrhage after abdominal surgery. Transarterial embolization is considered to be an effective and safe means in the management of postoperative hemorrhage.
