Abstract

Abstract : Segmental arterial mediolysis (SAM) is a non-arteriosclerotic, non-inflammatory arteriopathy characterised by dissecting aneurysms and most commonly found in abdominal arteries. A rupture of a visceral artery aneurysm is generally associated with high mortality. We present the case of a 57-year-old woman with a rupture of an intrahepatic aneurysm that led to intra-abdominal haemorrhage. The patient was surgically treated by evacuating the abdominal haematoma and ligature of the right hepatic artery. Histology of the right hepatic artery revealed the diagnosis of SAM. Six months postoperatively, the patient was in excellent physical condition with normal liver function and arterial blood flow of the right hepatic sections over collateral circulation.
