目的:应用能量多普勒超声评价肝动脉栓塞化疗合并超声引导下微波热凝固治疗肝癌的疗效。方法:35例共56个结节经组织学诊断证实的肝癌患者,首先采用肝动脉栓塞化疗,术后1～2天内进行超声引导下微波热凝固治疗。结果:56个结节能量多普勒超声检查治疗前结节内有血流信号者50个,治疗后血流信号消失者41个,占82％;采色多普勒超声检查治疗前结节内有血流信号者45个,治疗后血流信号消失者39个,86.7％.结论:能量多普勒超声优于彩色多普勒超声,是评价肝癌介入治疗的有效方法。
Objective: To evaluate the curative effect of hepatic arterial chemoembolization and hepatic arterial chemoembolization under the guidance of ultrasound in the treatment of liver cancer with energy Doppler ultrasound. Methods: A total of 56 nodules from 35 patients with histologically confirmed liver cancer were treated with transcatheter arterial chemoembolization (TACE). Ultrasound-guided microwave thermocoagulation was performed within 1-2 days after operation. Results: There were 50 blood flow signals in 56 nodules before treatment and 41 blood flow disappeared in 82 patients (82%). Color Doppler echocardiography was used to detect the former nodules There were 45 blood flow signals and 39, 86.7% disappearance of blood flow signals after treatment.Conclusion: Doppler ultrasound is superior to color Doppler ultrasound in the evaluation of interventional therapy of liver cancer.
