彩色多普勒观察门静脉癌栓对原发性肝癌血供的影响

Observation of the effect of portal venous cancerous embolism on the blood supply of primary hepatic carcinoma by color Dopplex ultrasound

目的:探讨门静脉癌栓及其栓塞的程度对原发性肝癌的血供的影响。方法:回顾性分析101例原发性肝癌的彩色多普勒超声图像,所有病例分为三组。Ⅰ组50例,原发性肝癌不伴门静脉癌栓;Ⅱ组25例为原发性肝癌伴充满型癌栓;Ⅲ组26例为原发性肝癌伴部分型门静脉癌栓。结果:肿瘤动脉峰速度(PSV)均值以Ⅱ组为高,阻力指数(RI)均值以Ⅰ组为高。各组间PSV、RI差异的显著性各不相同。结论:门静脉癌栓及其栓塞的程度对原发性肝癌动脉PSV和RI具有一定的影响。

Objective：To investigate the effect of portal venous cancerous embolism and its degree of embolism on the blood supply of primary hepatic carcinoma（pHC）.Methods：The color Doppler ultrasound images in 100 patients with PHC were analysed retrospectively.All cases were divided into 3 groups.50 cases pHC were not accompanied by portal venous cancerous embolism in group 1,25 cases of pHC were engorged with cancerous embolism in group 2,26 cases of pHC were accompanied by partial portal venous cancerous embolism in group 3.Results：The mean peak systolic velocity （PSV） in group 2 was higher than that in other two groups,while the mean resistance index （RI） in group 1 was higher than that in other two groups.The difference of PSV and RI among 3 groups was significant. Conclusion： PSV and RI of arterial flow of pHC were differently affected by portal venous cancerous embolism.
