目的：研究肝癌多重供血的影像学表现及意义和双途径介入治疗的必要性及临床意义。材料与方法：对２２例经Ｂ超、ＣＴ证实的肝癌患者在介入治疗术前进行了ＣＴＡ、ＣＴＡＰ检查，根据检查结果将患者的血供类型进行分类，根据不同的血供类型制定相应的治疗方案，同时针对肝动脉和门静脉进行双途径介入治疗。结果：本组１４例为肝动脉供血明显优势型，６例为肝动脉、门静脉供血相当型，２例显示门静脉供血稍优。本组２２例患者１年生存率为５９％（１３／２２）。结论：（１）ＣＴＡ、ＣＴＡＰ在显示肝癌多血供类型方面作用很大，有助于治疗方案的正确制定；（２）对于肝癌的治疗采用双途径介入治疗是必要的、有意义的。
Objective: To study the imaging features and significance of multiple blood supply of liver cancer and the necessity and clinical significance of two-way interventional therapy. Materials and Methods: Twenty-two patients with hepatocellular carcinoma confirmed by B-ultrasonography and CT were subjected to CTA and CTAP before interventional therapy. According to the results of the examination, the types of blood supply were categorized, and corresponding treatments were developed according to different types of blood supply. The protocol also provides dual-channel interventions for the hepatic artery and portal vein. RESULTS: In this group, 14 cases had obvious hepatic arterial supply, 6 cases had hepatic arterial and portal vein blood supply, and 2 cases showed slightly superior portal vein blood supply. The 1-year survival rate of this group of 22 patients was 59% (13/22). Conclusions: (1) CTA and CTAP play a significant role in the display of multiple blood supply types of liver cancer, which contributes to the correct formulation of the treatment plan; (2) It is necessary and meaningful to adopt dual-pathway intervention for the treatment of liver cancer.
