肝癌的动脉供血分类研究:规则性、变异性和寄生性供血

Classification Study of Arterial Blood Supply of Hepatic Cancer:Regular,Variant and Parasitic Blood Supply

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 of arterial blood supply of hepatic cancer and their clinical significance.Materials and Methods:Routine celiac arteriography before THAIE was underwent in 1116 patients with hepatic cancer,In 194 cases with suspectable anatomy variants of hepatic arteries,superior mesenteric arteriography and left gastric arteriography of 23 patients were done.In 114 patients that tumors were near diaphragma,selective inferior phrenic arteriography was performed.Results:An- giograms demonstrated regular blood supphy of hepatic cancer in 886 of these 1116 patients(79.4%)and variant in 230(20.6%). Variant blood supphy was further classified into five subtypes.Caliae arteriography showed parasitic blood supphy of gastroeploica dextra arteries in 47 of 1116 patients which the tumurs were located in inferior portion of right hepatic lobe.Parasitic blood supply of inferior phrenic arteries was comfirmed by selective inferior phtenic arteriography in 89 patients.Conclusion:Arterial blood sup- ply of hepatic cancer could be classified into three types:Regular,variant and parasitic blood supply.These types played an impor- tant role in angiographic diagnosis and interventioriml treatment of hepatic cancer.
