THE EFFECT OF HEPATIC-ARTERY LIGATION FOR IRRESECTABLE CAVERNOUS HEMANGIOMA OF THE LIVER

Abstract

During the past 19 years, 52 cases of hepatic cavernous hemangioma have been treated at our institution. Thirty patients underwent hepatic resection. In six patients, the extensive tumor mass invaded multiple segments or both lobes of the liver and complete resection was deemed hazardous. Therefore, hepatic artery ligation was carried out. In all six cases the hemangioma occupied more than two segments. Right hepatic artery ligation was done in five patients and left hepatic artery ligation in one. All are doing well without complication. The longest follow-up is 19 years and the shortest 2 years and 2 months following operation. Four patients have been followed for more than 4 years and in all patients there are no residual complaints. Computerized tomography (CT) revealed the reduction of the tumor size after ligation. One patient suffered from cholecystolithiasis 9 years after hepatic artery ligation, and at the time of cholecystectomy, a biopsy and microscopic examination of the lesion revealed evidence of fibrotic degeneration of the hemangioma. These findings indicate the effectiveness of hepatic artery ligation for treatment of hepatic cavernous hemangioma that are judged hazardous to resect.
