Abstract
Clinical and experimental evidence shows that hepatic artery ligation (HAL) is an effective method for treatment of nonresectable primary liver carcinoma (PLC). Improvement of subjective symptoms in 50-70% patients has reported, although effective duration is short and 30-50% of the enlarged liver could be decreased. Usually, arterial collateral of the tumors after HAL may be evident again in 4-6 weeks. There is arteriographic evidence of the appearance of collateral flow as early as the fourth days after HAL. HAL combined with irradiation was carried out in 17 cases between October 1978 to October 1982 in order to improve the prognosis of nonresectable PLC.
