Splanchnic artery aneurysms.

From 1970 to October 1991, 26 patients affected by splanchnic artery aneurysms were observed and treated at the Department of General and Cardiovascular Surgery, University of Milan, Italy. Three splanchnic artery aneurysms were operated on in emergency. Visceral artery aneurysms are often completely silent and are generally detected during diagnostic procedures performed in order to clarify some diagnostic questions. When symptomatic they present a characteristic clinical picture of the involved vascular district. Two patients affected by aneurysmal disease of the proper hepatic artery died after operation. All the other splanchnic aneurysms underwent a successful surgical procedure. This study is aimed at analyzing some characteristic clinical pictures, diagnostic methods, therapeutic procedures and postoperative results.
