Transarterial embolization in the management of acute lower gastrointestinal bleeding: an initial result

Abstract

Background: Acute lower gastrointestinal bleeding (ALGB) is an urgent, potentially life-threatening emergency, especially in case endoscopy is not identifiable or uncontrollable in management bleeding. Following the development of technology and applying minimal invasive modalities, endovascular treatment is more and more to be applied.

Primary endpoint: Figure out the rate of technical success, the clinical success and the complication relating to bowel ischemia of embolization in ALGB. Secondary endpoint: Figure out the rate of negative bleeding finding angiograms in diagnosis of ALGB

Method: Retrospective cohort study

Results: From 01/2019 to 01/2022, 23 embolisms were performed in total 35 procedures of 24 patients. There were 12 angiographies with negative bleeding finding result (34.3%). In embolization procedure, first embolisms were 21/23 and two procedures were re-embolism. The rate of technical success after first embolisms was 95.2% and clinical success reaches 76.2%. There was no major complication relating to bowel ischemia.

Conclusion: Transcatheter angiographic embolization is a safe and effective management for acute lower gastrointestinal bleeding with minimal invasive.
