Ligation of symptomatic celiac artery aneurysm without vascular reconstruction: Utilizing the natural collateral circulation of the celiac axis: A case report

IntroductionCeliac artery aneurysm is very rare visceral artery aneurysm. Symptomatic and ≥ 2.5 cm sized aneurysm requires treatment. Excision and revascularization is the most commonly employed procedure.Case presentationWe report a case of ligation and excision of celiac artery aneurysm extending onto the splenic and hepatic arteries without vascular reconstruction. The patient was a 52 year old lady who was evaluated for abdominal pain and was found to have a celiac artery aneurysm involving the hepatic and splenic arteries. She was evaluated with computerized tomography and digital subtraction angiography of the abdominal vessels. These confirmed good natural collaterals from the branches of superior mesenteric artery supplying the liver, stomach and spleen. We performed ligation and excision of the aneurysm and ligation and division of hepatic, splenic and left gastric arteries as the aneurysm was extending on to these vessels, without any vascular reconstruction, utilizing the natural collaterals from the superior mesenteric artery.DiscussionLigation of celiac artery aneurysm without revascularization is often done in emergency situations. Excision and revascularization is the treatment of choice to ensure adequate blood supply to liver, spleen and stomach. We could utilize the natural collateral circulation of celiac artery from superior mesenteric artery avoiding a complex procedure of revascularization.ConclusionWe present this because of the rarity of the disease as well as rarity of the technique of not performing vascular reconstruction. We emphasize on the pre-operative and operative evaluation of collateral circulation with conventional angiography and intraoperative Doppler respectively.
