Intestinal artery aneurysms are usually asymptomatic; however when rupture occurs, mortality rates of up to 75% have been reported. Celiac artery aneurysms are quite infrequent, only about 4% of all visceral aneurysms; their association with Aortic Aneurysms is found in 18% of cases; their association with popliteal aneurysms has not been documented so far. A case of an adult male with celiac artery aneurysm associated with Aortic and Popliteal Aneurysms is reported. The patient was operated. In a first procedure the celiac and aortic aneurysms were resected, an aortic graft was placed, and hepatic artery reimplantation was performed; in a second procedure the popliteal artery was resected and a vascular reconstruction performed. The postoperative course was uneventful, and the patient remains asymptomatic two years later. Diagnosis was based on a CT scan with selective visceral angiography. Elective surgical intervention must be performed when intestinal artery aneurysms are discovered.
