A rare case of pseudoaneurysm of posterior inferior pancreaticoduodenal artery related with hemosuccus pancreaticus: a case report

Abstract

Hemosuccus pancreaticus is a rare cause of obscure and intermittent upper GI bleeding, often life threatening. Usually seen in a patient with chronic alcoholic pancreatitis complicated with pseudoaneurysm of splenic artery in most of the cases. In the given case reports it was pseudoaneurysm of the posterior branch of inferior pancreaticoduodenal artery (IPDA) which accounts for less than 0.07% of total 10% of pseudoaneurysm of visceral arteries caused by hemosuccus pancreaticus. These patients usually present with an obscure moderate upper GI bleed. Early clinical, endoscopic and radiological diagnosis helps to determine the appropriate method of management. Most of the cases require the endovascular interventions like glue embolisation or metal coiling or beads, very few cases end up with explorative laparotomy. Here we report a rare case presentation of upper GI bleed due to pseudoaneurysm of IPDA in hemosuccus pancreaticus, it’s diagnosis and management.
