目的:研究肝癌的动脉供血分类及其临床意义。材料与方法:1116例肝癌在 THAIE 前行常规腹腔动脉造影,对疑为肝动脉变异的194例和23例分别作肠系膜上动脉及胃左动脉造影,对肿瘤邻近膈肌的114例作了选择性膈下动脉造影。结果:血管造影显示,1116例中,规则性供血886例(79.4%),变异性供血230例(20.6%),变异性供血又进一步分为5个供血亚型。腹腔动脉造影显示47例右肝下部的肝癌合并胃网膜右动脉的寄生性供血。选择性膈下动脉造影证实有89例台并膈下动脉寄生性供血。结论:肝癌的动脉供血可分为规则性、变异性和寄生性供血3大类,这对肝癌的造影诊断和介入治疗具有重要作用。
Objective: To study the classification and clinical significance of arterial blood supply in liver cancer. Materials and Methods: 1116 patients with hepatocellular carcinoma underwent conventional celiac artery angiography before THAIE. 194 patients and 23 patients with suspected hepatic artery changes were compared with superior mesenteric artery and left gastric artery, and 114 patients with tumor adjacent to diaphragm were selected. Infrapatellar arteriography. Results: According to angiography, in 1116 cases, 886 cases (79.4%) were regular blood supply, and 230 cases (20.6%) were variability blood supply. Variant blood supply was further divided into 5 blood supply subtypes. Celiac arteriography showed 47 cases of hepatocellular carcinoma with a right hepatic artery with parasitic blood supply to the right gastroepiploic artery. Selective subdiaphragm angiography confirmed the presence of 89 cases of parasital arterial parasitism. Conclusion: The arterial blood supply of hepatocellular carcinoma can be divided into three categories: regularity, variability and parasitic blood supply. It has an important role in the angiography diagnosis and interventional treatment of liver cancer.
