Management of Coeliac and Hepatic Artery Aneurysms: An Experience of 84 Cases.

To report outcomes following open or endovascular treatment of true hepatic and coeliac artery aneurysms at a single referral centre. This was a retrospective cohort study of consecutive patients treated for true hepatic and coeliac artery aneurysms between May 2002 and December 2021. Outcome measures included complications, graft patency, and survival rate. Overall, 84 patients were included with a median age of 63 years (interquartile range 55, 79). The majority (76%) of the patients were men. Frequent comorbidities included a history of tobacco (69%), hypertension (65%), hyperlipidaemia (32%), and diabetes (15%). Multiple synchronous aneurysms were detected in 22 patients (26%). There were 33 (39%) symptomatic aneurysms (abdominal pain without rupture [n = 18], rupture [n = 10], and sepsis [n = 5]). Seventeen patients (20%) had mycotic aetiology. Fifty patients (60%) underwent endovascular treatment with either covered stent placement (n = 29) or coil embolisation (n = 21), and 34 patients (40%) were treated with open surgery using allogenic iliac artery (n = 15), autologous saphenous vein (n = 15), GoreTex graft (n = 2), or ligation (n = 2). The complication rate was 32% in the open group and 18% in the endovascular group (p = .048). The overall 90 day post-operative mortality rate was 1.2%, five year primary patency was 90.0%, five year survival rate was 81.2%, and mean follow up was 6.9 ± 4.2 years. Endovascular treatment is the preferred approach whenever technically possible. Despite higher post-operative morbidity, an open approach with vascular reconstruction using autologous or allogenic vascular grafts yields acceptable long term results.
