Visceral artery pseudoaneurysms or aneurysms (VAPA) can form secondary to a variety of congenital, traumatic and inflammatory pathologies such as pancreatitis. Massive haemorrhage into the gastrointestinal tract or the peritoneal cavity from visceral artery pseudoaneurysms or aneurysms can result in death in 40% of cases. Gastroduodenal artery aneurysm (GDA) rupture is a rare, life-threatening condition and bleeding into the gastro-intestinal tract is the most rapidly fatal complication of an arterial visceral aneurysm. They represent 1.5% of all visceral artery aneurysms and are classified into true and pseudo aneurysms depending on their aetiology. They are challenging to diagnose and may prove fatal if they rupture. They can be managed with a surgical, endovascular or a combined approach. The authors present the case of a 63 year old female presenting with hypotension and abdominal pain. A ruptured aneurysm of her gastroduodenal artery was subsequently found. She was successfully treated with transcatheter coiled embolization. The aetiology, clinical presentation and management of a gastroduodenal artery aneurysm are discussed. This case acts as a cautionary reminder of considering a ruptured GDA in the differential diagnosis in patients presenting to the Emergency Department with hypovolaemic shock and an acute abdomen.
