Abstract
Hepatic artery aneurysms (HAA) are rare (20% of all visceral arteries). Most often, HAAs are asymptomatic and detected at autopsy. However, their ruptures and/or bleeding following pressure ulcers in visceral gastrointestinal organs are a significant clinical and diagnostic problem. We present 2 patients with obstructive jaundice and hemobilia. Diagnostics revealed aneurysm of the right hepatic artery with arterio-biliary fistula. Life-threatening hemobilia is a consequence of HAA rupture into biliary system. Endovascular approach is preferable for HAA without clinical manifestations. Awareness of this disease is important for early detection and active surgical intervention before possible complications.
