Treatment of splenic artery aneurysm after distal splenorenal shunt. A case report.

A patient with splenic artery aneurysm which developed after creation of selective distal spleno-renal shunt for hepatic cirrhosis and portal hypertension was presented. Three months after operation, an aneurysm of the splenic artery with a diameter of about 20 mm was detected. This aneurysm reached 4 cm three months later, and a resection was carried out. An arterial continuity was established by means of end-to-end anastomosis of the sectioned arterial ends. Because the flow through the splenic artery was about 60% of the total flow of the selective distal spleno-renal shunt, it is important to maintain continuity in order to avoid thrombosis of the shunt.
