摘　　要：目的探讨肝癌侧支供血的影像学类型和介入治疗方法探讨。方法分析46例肝癌患者的数字减影血管造影(DSA)和螺旋CT等影像学表现,分析侧支供血类型,提出相应介入治疗方法。结果46例肝癌侧支供血的影像学表现类型可分为:①肝动脉型,又可分为叶间(3例)和段间(15例)两个亚型;②非肝动脉型,包括固有血管亚型(16例)和寄生血管亚型(5例);③混合型(7例)。结论肝癌侧支供血分型对避免侧支供血形成和选择合适的介入治疗方法具有指导意义。固有血管亚型中的无优势供血侧支、寄生血管亚型者不适宜常规介入方法治疗。Objective To investigate the imaging typology of the collateral blood flow of the hepatocellular carcinoma,the mechanisms and the significance of intervention therapy.Methods 46 cases of hepatocellular carcinoma by digital subtraction angiography（DSA） helical CT imaging findings were reviewed for the typology of the collateral blood supply of hepatocellular carcinoma and the corresponding interventional therapies were proposed.Results The imaging findings of collateral blood typology in the 46 cases were classified into： 1.Hepatic artery type with the two subtypes（3 cases of the interlobar subtype 15 cases of the intersegment subtype）.2.Non-hepatic artery type with two subtypes（16 cases of the intrinsic vascular subtype 5 cases of the parasitic vascular subtype）.3.Mixed type（7 cases of both types）.Conclusion The collateral supply blood typology is significant in the prevention of the formation of collateral supply blood and the selection of appropriate interventional therapies,while routine interventional therapy is not suitable for the non-dominant collateral blood supply in the intrinsic vascular subtype as well as the parasitic vessel subtype.
