肝动脉解剖变异及多支供血在肝癌介入治疗中的临床意义

目的:研究肝动脉解剖变异和肝癌多支供血及临床意义。材料与方法:140例肝癌行介入治疗前常规腹腔动脉和肠系膜上动脉造影,邻近膈肌病灶加作选择性膈下动脉造影,分析造影图像。结果:肝动脉常见型113例(80.8%),变异27例(19.2%)。病灶单纯由肝动脉供血92例,48例存在除肝动脉外的多支血管供血。结论:熟悉肝癌的血供特点可指导术者方便快捷插入导管,发现除肝动脉外的供血动脉,并给予化疗栓塞以确保疗效。

The Anatomic Variations of Hepatic Artery and Multiple Feeding Vessels and Its Clinical Significance on Interventional Therapy of Hepatocellular Carcinoma

Purpose: To study the clinical value of variations of hepatic artery and multiple feeding vessels of hepatocellular carcinoma.Materials and Methods:140 cases with hepatocellular carcinoma were treated by angiography of celiac artery and mesenterica superior artery,the diaphragmatic artery angiography were performed that hepatocellular carcinoma were close diaphragm,the pictures in angiography were analysed.Results:The distribution of hepatic arteriae was showed as typical and variation in 113 cases(80.8%) and 27 cases(19.2%) respectively.92 cases had simple hepatic arteries,48 cases had multiple feeding vessels.Conclusion:The blood that acguit with hepatocellular carcinoma can ensure the accuracy of intubation of hepatic artery and the arteriae to be occluded completely in the therapy of hepatocellular carcinoma.
