Abstract

Aims: To discuss treatment strategies for non-traumatic, non-iatrogenic hepatic artery aneurysms (HAAs) in the presence of an arteriobiliary fistula, illustrated by a case and followed by a comprehensive review of the literature. Methods: Following the PRISMA guidelines, 24 eligible HAA cases presenting with haemobilia were identified. Characteristics of patients, aneurysms, treatment strategies and their outcomes were collected. Results: A 69 year old patient with no previous hepatobiliary intervention or trauma, presented with jaundice and haemobilia caused by a HAA. Initial treatment by endovascular stenting was chosen to prevent ischaemic liver complications. Unfortunately, this strategy failed because of stent migration due to ongoing infection leading to a type 1A endoleak. The patient had to be converted to open surgery with ligation of the HAA. The patient recovered uneventfully and no complications occurred during the following 12 months. Comprehensive literature review: Of the 24 cases, nine had a true HAA and 15 were pseudo/mycotic aneurysms, mainly caused by endocarditis or cholecystitis. The majority were located in the right hepatic artery. In 20 cases, an endovascular first approach was chosen with embolisation, none with covered stents. Three of these cases had to be converted to open surgery because of rebleeding. In all open (primary or secondary) cases, ligation of the HAA was performed. One patient in these series died. No liver ischaemia or abscesses were reported, although one patient developed an ischaemic gallbladder. Conclusions: Patients who present with a HAA and haemobilia may be treated safely by embolisation or open ligation. Using a covered stent graft in these patients can cause problems due to ongoing infection and should be monitored closely by imaging. Publication bias and lack of long term follow up imply cautious interpretation of these findings.
