Balloon-Occluded Retrograde Transvenous Obliteration (BRTO) is an interventional radiological technique used to manage and prevent gastric variceal bleeding, commonly performed in Asia. The management of gastric variceal hemorrhage has much less confounding evidence than oesophageal varices. There have been few studies on BRTO carried out in Europe and America


This audit aims to capture the technical success and clinical outcomes for all patients that had BRTO performed in a Tertiary Referral Centre.


All patients that underwent BRTO in the Tertiary Referral Centre were included in the audit. Data was collected retrospectively from 2014-2022.


There were seven patients included in total (n=7). All patients had a 1 month survival (100%) and 1 year survival occurred in 6 of the patients. Cause of death for 1 patient was hypoxic ischaemic encephalopathy. 4 of the patients were followed up with OGD after BRTO. 3 of the patients had experienced oesophageal variceal bleeding at 1 year.


Indication for BRTO was gastric variceal bleeding in 100% of patients. Classification of gastric varices was not captured in the audit. Technical success of BRTO procedure was 100% Two thirds of suitable patients had OGD at 1 month after BRTO. 28.6% of patients had worsening of their oesophageal varices (OV) after BRTO. 28.6% of patients had oesophageal variceal bleeding at 1 month post BRTO, 100% of whom had Grade 3 OV. 42.86% of patients had OV bleeding at 1 year post BRTO.
