Percutaneous Treatment of a Large Celiac Artery Aneurysm Using a Stent Graft

Abstract

Celiac trunk aneurysm is a rare finding. Most patients are symptomatic at the time of diagnosis but occasionally such aneurysms are detected incidentally during diagnostic imaging for other diseases. Since the anomaly was first described in 1745(1) fewer than 180 cases have been reported in the international medical literature.(2) Atherosclerotic aneurysms of the celiac artery (CAAs) comprise approximately 4–6% of all visceral aneurysms.(3–4) Early surgical intervention has reduced the rupture rate to 7% in recent years.(5) Early recognition and intervention are crucial because the operative mortality rate associated with ruptured celiac artery aneurysms is around 40%.(6) There are no absolute size criteria associated with significant rates of CAA rupture, but 2 cm appears to warrant intervention in most series.(7–8) Surgical reconstruction, surgical ligation, intraluminal embolization, thrombin injection and endovascular grafting have all been reported with success/9”11) We present a case of a 6.9 cm symptomatic celiac artery aneurysm treated successfully with endovascular stenting.
