目的：探讨门静脉癌栓及肝硬化对肿瘤血供的影响。方法：本研究回顾性分析１０８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：单纯性肝癌，５４例；Ⅱ组：肝癌合并门静脉癌栓，２７例；Ⅲ组：肝癌合并肝硬化，２７例。结果：肿瘤动脉收缩期峰值流速（ＰＳＶ）均值以Ⅱ组最高，阻力指数（ＲＩ）均值以Ⅲ组最高。当肿瘤≤１０ｃｍ时，各组间ＰＳＶ、ＲＩ均值差异具显著性（ｐ＜０．０１～０．０５）。结论：门静脉癌栓及肝硬化对肝癌动脉ＰＳＶ和ＲＩ具有一定影响。
Objective: To investigate the effect of portal vein tumor thrombosis and cirrhosis on tumor blood supply. Methods: This study retrospectively analyzed 108 cases of primary liver cancer with color Doppler ultrasound images, all cases were divided into three groups. Group I: Simple liver cancer, 54 cases; Group II: liver cancer with portal vein tumor thrombus, 27 cases; Group III: liver cancer with liver cirrhosis, 27 cases. Results: The mean peak velocity of systolic arterial flow (PSV) was highest in group II, and the mean value of resistance index (RI) was highest in group III. When the tumor was ≤10cm, there was a significant difference in PSV and RI between groups (p<0.01-0.05). Conclusion: Portal vein tumor thrombosis and cirrhosis have certain effects on PSV and RI of hepatocellular carcinoma.
