目的观察高强度聚焦超声治疗机对原发性肝癌合并门静脉癌栓治疗的有效性,临床应用价值及安全性。方法应用FEP-BYO2型高强度聚焦超声治疗机对肝癌合并门静脉癌栓的50例患者进行治疗,观察治疗后门静脉癌栓的血流变化,癌栓回声改变及癌栓大小的改变以及患者肝功能、腹水变化情况等。结果 50例患者经治疗后门静脉内癌栓回声增强,癌栓大小均有不同程度的缩小,门静脉血流改善,腹水减少,肝功能指标好转。结论用FEP-BYO2型高强度聚焦超声治疗原发性肝癌合并门静脉癌栓具有安全无创、疗效确切的治疗作用。
Objective To observe the effectiveness, clinical value and safety of high intensity focused ultrasound in the treatment of primary hepatocellular carcinoma with portal vein tumor thrombus. Methods Fifty patients with hepatocellular carcinoma complicated with portal vein tumor thrombus were treated with FEP-BYO2 high-intensity focused ultrasound therapy machine. The changes of blood flow in portal vein tumor thrombus, changes of tumor embolism and the size of tumor thrombus and changes of liver function , Ascites changes and so on. Results 50 cases of patients after treatment of portal vein tumor thrombus echo enhancement, the size of tumor emboli were reduced to varying degrees, portal vein blood flow, ascites decreased, liver function improved. Conclusion FEP-BYO2 high-intensity focused ultrasound in the treatment of primary hepatocellular carcinoma with portal vein tumor thrombus has a safe and noninvasive therapeutic effect.
