目的 :探讨肝动脉多普勒血流灌注指数 (DPI)与门静脉逆流发生率 (PVCF)的相关性及二者与肝癌肝内转移的关系。方法 :应用彩色多普勒检测 4组不同人群的 DPI与 PVCF;结果 :1DPI以转移组最高 ,依次为肝癌组、对照组、肝硬化组 (P<0 .0 5～ P<0 .0 0 1) ;PVCF以转移组最高 ,依次为肝癌组、肝硬化组、对照组 (P<0 .0 5～ P<0 .0 0 1) ;2肝癌组与转移组 DPI与 PVCF的相关系数分别为 r=0 .6 74、 r=0 .75 9;3以 DPI≥ 0 .30作为判定肝癌已发生肝内转移的指标敏感性 99.2 %、特异性 78.8%、符合率 92 .6 % ;结论 :1肝硬化基础上的肝癌及伴肝内转移者的 DPI与 PVCF呈正相关关系 ;2 DPI升高、 PVCF增加能促进肝癌肝内转移 ,且三者形成恶性循环
Objective: To investigate the relationship between hepatic artery Doppler perfusion index (DPI) and portal vein reflux (PVCF) and their relationship with intrahepatic metastasis. Methods: DPI and PVCF in 4 different groups were detected by color Doppler;Results: 1 DPI was highest in metastasis group, followed by liver cancer group, control group, liver cirrhosis group (P<0.05). P<0. 1) PVCF was the highest in the metastatic group, followed by liver cancer, liver cirrhosis, and control (P<0.05-P<0.01); 2 The correlation coefficients of DPI and PVCF in liver cancer and metastasis groups For r=0. 674, r=0.75 9;3 with DPI ≥ 0 .30 as the index for judging liver cancer with intrahepatic metastasis, the sensitivity was 99.2%, the specificity was 78.8%, and the coincidence rate was 92.6%; :1 The DPI of liver cancer and liver metastasis based on liver cirrhosis are positively correlated with PVCF; 2 The increase of DPI and the increase of PVCF can promote the intrahepatic metastasis of liver cancer, and the three forms a vicious circle
