【摘要】 目的:探讨肝癌合并门静脉栓子的超声类型及临床意义。方法:选择肝癌伴门静脉癌栓32例(PVTT组),肝癌伴门静脉血栓18例(PVBT组)。肝动脉插管介入治疗后,PVTT组32例、PVBT组4例均作门静脉途径介入治疗。2组患者均排除肝动静脉瘘。结果:PVTT组门静脉完全阻塞型17例,不全阻塞型6例,侵犯门静脉管壁型9例。PVBT组门静脉完全阻塞型10例,不全阻塞型8例。PVTT组中,彩超检查显示血供29例,PVBT组仅1例疑有少许血供,2组血供差异有统计学意义(χ2=38.11,P<0.01)。结论:门静脉栓子的超声表现分型具有一定临床应用价值。更多还原

【Abstract】 Objective:To investigate the clinical significance and the image types of ultrasound of hepatocellular carcinoma(HCC) with portal vein tumor thrombus(PVTT) and portal vein blood thrombus(PVBT).Methods:HCC with PVTT of 32 cases(PVTT group) and HCC with PVBT of 18 cases(PVBT group) by transcantheter hepatic arterial chemo-embolization(THAE) were reported.Thirty-two cases in PVTT group and 4 cases in PVBT group were treated with ultrasound-guided percutaneous portal pathway.The hepatic arteio-venous fistula in the two groups was excluded.Results:According to the image classification of ultrasound,in PVTT group,there were including the type of complete obstruction of the portal vein lumen(n=17),the type of incomplete obstruction(n=6) and the type of invasion the portal wall(n=9).In PVBT group,there were including the type of complete obstruction of the portal vein lumen(10 cases) and the type of incomplete obstruction(8 cases).In PVTT group,the blood supply was revealed in 29 cases by the ultrasound examination while in PVBT group,only one case was with uncertainly blood supply,there was a highly significant difference about the blood supply between PVTT and PVBT group(χ2=38.11,P<0.01).Conclusions:It has a great value in clinical application of the image classification of ultrasonic findings about portal vein thrombus and PVTT.更多还原
