目的探讨原发性肝癌化疗栓塞中经肠系膜上动脉行间接门静脉造影的技术改进方法。资料与方法选取68例行介入治疗的原发性肝癌患者,其中20例未评级,不设定动-静脉期间隔时间,使用相同造影程序;48例评级,依据个体情况设定动-静脉期间隔时间,制定相应造影程序。分别分析68例造影图像,依据是否清晰显示门静脉系统分为高、中、低质量图像。结果 20例未评级患者,3例造影图像为高质量,10例为中质量,7例为低质量;48例评级患者,35例造影图像为高质量,13例中质量。结论在经肠系膜上动脉行间接门静脉造影前根据患者的肝功能、有无门静脉癌栓及门静脉高压等因素来设定动-静脉期间隔时间,确定个体化造影程序,能保证取得高质量的图像。
Objective To investigate the technical improvement of indirect portal vein angiography through superior mesenteric artery in chemoembolization of primary liver cancer. Materials and Methods Sixty-eight patients with primary hepatocellular carcinoma who underwent interventional therapy were selected. Twenty patients were not rated, no arteriovenous phase interval was set, and the same procedure was used. Forty-eight patients were graded according to their individual circumstances. Interval, develop appropriate contrast procedures. 68 cases of angiography were analyzed, based on whether it is clear that the portal vein system is divided into high, medium and low quality images. Results Twenty patients were not rated. Three of them were high quality, 10 were middle quality and 7 were low quality. Among the 48 patients with grading, 35 were high quality and 13 were middle quality. Conclusion According to the patient’s liver function, presence of portal vein tumor thrombus and portal hypertension, the interval of arteriovenous phase can be set before indirect mesenteric arteriography through the superior mesenteric artery to determine the individual imaging procedure, which can ensure high quality images .
