彩色多普勒超声对原发性肝癌肝动脉栓塞前后肝血管的血流动力学观察

目的观察原发性肝癌肝动脉栓塞前后肝血管的血流动力学改变。方法应用彩色多普勒超声(CDFI)对60例原发性肝癌患者行肝动脉栓塞(TAE)治疗前后肝血管的血流动力学变化进行研究。结果(1)TAE后肝动脉血流减少(P<0.05),而阻力指数(RI)和肝动脉内径改变不明显(P>0.05);(2)门静脉血流于TAE后增加(P<0.05),门静脉内径无明显变化(P>0.05);(3)TAE后瘤体明显缩小,瘤体血供减少(P<0.05);(4)肝静脉的血流治疗前后无明显改变(P>0.05)。结论CDFI是观察原发性肝癌肝动脉栓塞治疗前后较好的影像学检查方法。

Color Doppler Observation of Liver Vascular Hemodynamics before and after Hepatic Artery Embolization Treatment in Patients with Hepatocellular Carcinoma

Objective To observe changes of liver v ascular hemodynamics before and after hepatic artery embolization (TAE) treatmen t in patients with hepatocellular carcinoma(HCC). Methods Changes of liver vascular hemodynamics before and after hepatic artery embolization treatment were studied in sixty patients with hepatocellular carcinoma(HCC) with Color Dopper Flow Imaging(CDFI). Results (1)After TAE,hepatic artery flow decreased(P <0.05) but resistant indexes(RI) and internal diameter of hepatic artery had n o significant change(P>0.05);(2)Portal venous flow increased after TAE( P<0.05),however internal diameter of portal vein had no significant change( P>0.05);(3) Hepatic tumor dwindled obviously and the blood supplying of h epatic tumor decreased(P<0.05) after TAE;(4)Before and after TAE no diffe rence was seen on hepatic vein flow (P>0.05). Conclusions Color Doppler Flow Imaging is the better exa mining means in imaging which is used to observe liver vascular hemodynamics bef ore and after hepatic artery embolization(TAE) treatment in patients with hepato cellular carcinoma.
