BACKGROUND: Splanchnic artery areurysm is a rare but clinically relevant disease, showing a high mortality rate in emergency surgery. Reports on @entity439 are rare and often anecdotal. The aim of this study is to discuss data obtained from 16 @entity1 in a single vascular surgery center. MATERIALS AND METHODS: Between January 1987 and December 2000, 16 @entity1 underwent surgery for splanchnic @entity438 . In 13 @entity1 the localization was single (in two associated with an infrarenal @entity1028 ) and in 3 @entity1 multiple. The arteries involved were: splenic (8), @entity4386 , superior mesenteric (3), ileocolic (2), and pancreatoduodenal (1). 13 @entity1 were asymptomatic and 3 presentec with @entity490 . All @entity1 underwent CT scan, and abdominal aortic and selective visceral artery angiography. Before surgery, all @entity1 underwent cerebral MR or cerebral CT scan. 13 @entity1 underwent open vascular surgery; 3 @entity1 (2 splenic and 1 hepatic) underwent endovascular procedure (angioembolization). Histological examination of the aneurysmal wall was obtained in 14 @entity1 . Ultrasound examination was performed after 6 months, then yearly. 14 @entity1 underwent abdominal CT scan during the long-term follow-up. RESULTS: Perioperative mortality was absent. 12 cases were classified as displastic, with minor or major secondary @entity731 changes, and in many cases severe calcications. 2 cases were classified as @entity731 . Cerebral MR did not show any cases of @entity1779 . One @entity1 was lost at follow-up after 9 years. One @entity1 showed a recurrence at 6 years (superior mesenteric artery): the @entity1 underwent a new surgical procedure and died 20 days after surgery for intestinal @entity1188 . All abdominal follow-up CT scans show good results of the vascular reconstruction and escluded other new visceral or aortic @entity439 . CONCLUSIONS: @entity438 are an uncommon form of @entity455 showing a high postoperative mortality rate in emergencies. Surgery, and in selected cases, endovascular treatment, can successfully manage splanchnic @entity455 and low recurrence.
