[Hepatic artery aneurysm as a cause of hemobilia].

1) Haemobilia must be kept in mind as a cause of gastrointestinal haemorrage. 2) The presence of an hepatic artery aneurysm gives a peculiar triad of symptoms: abdominal pain, gastrointestinal haemorrage and jaundice. 3) Selective angiography is the elective diagnostic aid. 4) The diagnosis may be difficult also at operation, because the aneurysms can be very small. 5) The most used surgical treatment are ligation of the hepatic artery, the excision of aneurism, the endoaneurysmorrhaphy or the end-to-end anastomosis.
