摘要
目的:探讨多普勒超声评价经肝动脉化疗栓塞术(TACE)治疗原发性肝癌(HCC)疗效的价值。方法:对51例原发性肝癌TACE术前、术后行多普勒超声检查,用二维超声观察肿瘤大小及内部回声改变。彩色多普勒超声(CDFI)观察肿瘤血供情况及脉冲多普勒(PW)记录肝动脉、门静脉血流动力学改变。结果:TACE术后大多数肿瘤均有不同程度缩小,肿瘤血供明显减少(P<0.001),其血供减少程度与肿瘤缩小程度呈正相关(r=0.757,P<0.001)。肝动脉峰值流速明显下降,门静脉血流速度增快(P<0.001)。结论:多普勒超声能客观判断肿瘤大小及血流灌注状态,是目前检验肝癌TACE术后效果较理想的影像学检查方法之一。
Objective： To discuss the applicable value of Doppler imaging in evaluating transcatheter artery chemoembolization（TACE） effects in hepatocellular carcinoma. Methods： Doppler imaging was performed in 51 patients with hepatocellular carcinoma before and after TACE. The size and the change of echo of the tumor were observed by B-mode ultrasound. Blood supply of the tumor were assessed by color Doppler flow imaging（CDFI） or color Doppler energy（CDE）. The changes of the hepatic artery and portal vein hemodynamics were observed by pulse Doppler. Results： After TACE, a majority of the tumor volume obviously reduced, the blood flow within and around the tumor obviously decreased（P〈0.001）, a positive correlation was between the decrease of blood flow and the reduce of tumor volume（r=0.75, P〈0.001）, the peak velocity of hepatic artery dropped significantly, the velocity of portal vein increased significantly（P〈0.001）. Conclusion： Doppler imaging can assess objectively the size and the blood flow perfusion of liver tumor, it is a better imaging technique in evaluating TACE effects of hepatocellular carcinoma at present.
