彩色多普勒超声诊断原发性肝癌并门静脉癌栓的价值

目的探讨彩色多普勒超声诊断原发性肝癌(HCC)并门静脉癌栓(PVTT)的价值。方法回顾性分析彩色多普勒超声诊断HCC并PVTT 50例患者的超声检查资料,并与50例正常组(无肝胆疾病)的超声检查结果对照。结果声像图表现为门静脉内径明显增宽,血流束变细或充盈缺损,甚至中断;癌栓内探及动脉血流频谱12例(24.0%),门静脉海绵样变性18例(36.0%)。结论彩色多普勒超声不仅可以较准确地诊断HCC,而且还能反映门静脉及肝动脉的形态及血流动力学变化,对HCC并PVTT的诊断具有重要的临床价值。

Value of color doppler ultrasond in diagnosis of portal vein tumor thrombus combined with primary hepatic carcinoma

Objective To investigate the value of color doppler ultrasond on diagnosis of portal vein tumor thrombus （PVTF） in primary hepatic carcinoma （ HCC ）. Methods The data of 50 eases of primary hepatic carcinoma with portal vein tumor thrombus were retrospectively analyzed, and were compared with the data of 50 cases in the normal control group. Results The sonographie graph showed that portal vein diameter was obviously enlarged and that blood flow was beamed thinning or filling de- feet, even interrupted. Arterial blood flow spectrum was seen in tumor thrombus of 12 cases（ 24.0% ）. Portal vein transformation was seen in 18 cases（36. 0% ）. Conclusion Color Doppler ultrasound can not only accurately diagnose HCC, but also can re- flect the morphology of portal vein and hepatic artery and hemodynamie changes. It has important clinical value for the diagnosis of HCC combined with PVTT.
