原发性肝癌膈下动脉侧支供血研究

Study of the Collateral Blood Supply of Inferior Phernic Artery (IPA) in Primary Hepatic Carcinoma

158例原发性肝癌动脉造影资料提示40例有膈下动脉侧支供血。对该40例均作了选择性膈下动脉造影进一步观察。膈下动脉参与肝癌供血可分两种类型,一种是膈下动脉与肝动脉交织供血;另一种是部分以膈下动脉供血为主,后者常表现为肝癌上部有一呈‘半月’形的以膈下动脉供血为主的区域。凡是有膈下动脉参与供血的肝癌,均应通过膈下动脉对其治疗,以提高疗效。

There were 40 cases of primary hepatic carcinoma with IPA collaterals from angiography of 158 patients. All of the 40 cases IPA collaterals had been carried the selective angiography to have a better observation. The blood supply of IPA and hepatic artery to liver neoplasms could be classified into two kinds of forms, one was interweaving blood supply of IPA and hepatic artery; the other was the blood supply mainly by the IPA. The latter usually showed an area semilunar-like in shape in the upper part of the tumor. If the liver tumors can be seen to be supplied by IPA collaterals, IPA should be emboliged to increase the treatment effect.
