This present report describes a unique case of a patient with ileal varices revealed by recurrent bleeding from vesical varicosities. Ileal varices were associated with portal hypertension secondary to portal thrombosis. An unusual ileovesical shunt was demonstrated by the venous phase of the superior mesenteric arteriogram. This shunt was favored by adhesions between an abnormal ileal loop, which was infiltrated with ova of schistosoma mekongi, and the superior vesical wall. The patient was treated successively by lysis of adhesions and ileal resection. No portacaval shunt was performed.
