Uncommon visceral artery aneurysms.

Aneurysms of the hepatic, celiac, and superior mesenteric arteries are uncommon visceral artery aneurysms. They are often difficult to diagnose, and symptoms of expansion or rupture may easily be misinterpreted as suggestive of primary gastrointestinal disease. These aneurysms appear to have a significant propensity toward rupture. Indications for surgery include an aneurysm three to four times the original size of the vessel, x-ray evidence of increasing size of the aneurysm, or a calcified aneurysm larger than 3 cm. We believe that in all patients who are acceptable surgical candidates, a diagnosed visceral artery aneurysm should be resected.
