原发性肝癌通常由肝总动脉——肝固有动脉及其分支供血,然而临床发现一部分肿瘤巨大,除有用动脉的主(?)供血外,同时存在另外的侧支供血。我院自1994年4月至1998年4月对192例肝癌行经导管肝动脉栓塞化疗(TAE),发现同时存在侧支供血27例,本文针对侧支供血的意义、寻找及处理等问题进行探讨。 临床资料 192例原发性肝癌病例,男性121例,女性71例,年龄23～82岁,平均43.2岁,巨块型142例,结节型34例,弥漫型16例。肿瘤直径2.3～23cm,平均10.5cm。病灶主要位于右叶上部50例,右叶下
Primary hepatic carcinoma is usually supplied by the common hepatic artery - the hepatic artery and its branches. However, a large number of tumors are found clinically. In addition to the main arterial blood supply, additional collateral blood supply exists. In our hospital from April 1994 to April 1998 192 cases of liver cancer undergoing transcatheter arterial chemoembolization (TAE), and found that there are 27 cases of collateral blood supply, the purpose of this article for the collateral blood supply to find and deal with the issues discussed . Clinical data 192 cases of primary liver cancer cases, 121 cases of males and 71 females, aged 23 to 82 years, mean 43.2 years, 142 cases of bulky, nodular 34 cases, diffuse 16 cases. Tumor diameter 2.3 ~ 23cm, an average of 10.5cm. The lesions were mainly located in the upper right lobe of 50 cases, the right lobe
