应用彩色多普勒超声探讨肝癌患者门静脉逆流与肝癌肝内转移的相关性

THE RELATIONSHIP BETWEEN THE COUNTERCURRENT OF PORTAL VEIN AND INTRAHEPATIC CANCER METASTASIS IN PATIENTS WITH HEPATIC CARCINOMA UNDER COLOR DOPPLER FLOW IMAGING

为探讨肝癌患者门静脉逆流与肝癌肝内转移的关系 ,应用灰阶超声观测肝炎肝癌组、非肝炎肝癌组门静脉癌栓和癌肿肝内转移情况 ;彩色多普勒超声检测肝炎肝癌组、非肝炎肝癌组、肝硬化组与对照组门静脉 肝动脉瘘及门静脉逆流的发生率。结果显示 ,肝炎肝癌组门静脉逆流的发生率及门静脉癌栓、癌肿肝内转移发生率均高于非肝炎肝癌组 (P <0 .0 1) ;肝硬化组门静脉逆流的发生率高于对照组 (P <0 .0 1) ;肝炎肝癌组与非肝炎肝癌组肿块内及周围的门静脉 肝动脉瘘发生率无明显差别 (P >0 .0 5 )。

The present study was performed to investigate the relationship between the countercurrent of portal vein and intrahepatic cancerometastasis in patients with hepatic carcinoma under color Doppler flow imaging.To display the situation of portal carcinomatous thrombosis and intrahepatic cancerometastasis, two dimensional ultrasound was carried out in patients with hepatitis hepatocarcinoma and non hepatitis hepatocarcinoma. Also, color Doppler flow imaging was employed to examine the incidence of the pylic countercurrent and the portal vein hepatic artery fistula in four groups: hepatitis hepatocarcinoma group, non-hepatitis hepatocarcinoma group, hepatocirrhosis group and control group. The results showed that the incidences of portal carcinomatous thrombosis,intrahepatic cancerometastasis and the incidences of the countercurrent in portal vein were higher in hepatitis hepatocarcinoma group than those in non hepatitis hepatocarcinoma group ( P <0.01), but the incidence of the portal vein hepatic artery fistula was not markedly different between hepatitis hepatocarcinoma and non hepatitis hepatocarcinoma groups. The countercurrent of portal vein is an important factor in intrahepatic cancerometastasis in patients with hepatic carcinoma.
