Endovascular treatment of psuedoaneurysm arising from common hepatic artery bifurcation with complete disruption of gastroduodenal artery and high flow arterioportal fistula.

Arterio-portal fistulas (APFs) are characterized by anomalous communication between arteries and the portal vein (PV) system. Treatment of APF is imperative as an emergency or if there is development of portal hypertension/heart failure in chronic cases. Both endovascular and surgical managements can be attempted, however since endovascular management carries comparatively low intra and post procedural morbidity it is mostly preferred. This is a case report on endovascular management of post-traumatic pseudoaneurysm arising from bifurcation of common hepatic artery with complete disruption of the gastroduodenal artery and high-flow APF. This report describes the intraprocedure challenges in exclusion of fistula from the circulation, without disruption of portal system and anticipation of recruitment of new collateral feeders to the fistula immediate post exclusion with its embolization, which needs appropriate positioning of the catheter prior to exclusion of the fistula.
