Abstract
Prognosis of 16 patients with hepatic tumors and angiographically proven arterioportal fistulas was analysed in relation to treatment. Six patients received only conservative therapy; they all died of variceal bleeding in the course of two months after angiography. Hepatic resection was performed in four patients; three of them are still alive 13–52 months later including two free of both the tumor and portal hypertension. Hepatic artery embolization was carried out in six patients. All of them died in 2–36 months after the procedure, but only two from gastroesophageal hemorrhage. It is concluded that prognosis of arterioportal fistulae in liver neoplasms is poor due to hyperkinetic portal hypertension and following variceal bleeding. Hepatic resection of both the tumor and the fistula is the treatment of choice. In unresectable cases hepatic artery embolization will decrease the risk of variceal hemorrhage.
