Surgical treatment of celiac artery aneurysm associated with median arcuate ligament.

Celiac artery aneurysms are rare but potentially fatal because of the risk of rupture. Atherosclerosis and fibrous dysplasia are the two most common etiologies. Median arcuate ligament compression of the celiac artery is common but usually asymptomatic. We report three cases of post-stenotic celiac artery aneurysm with median arcuate ligament compression admitted to our hospital over the past two years. Although the incidence is rare with only 8 cases reported in the literature, a median arcuate ligament may have a role in the development of celiac artery aneurysms and its presence can influence the surgical strategy.
