超声在冷循环射频治疗肝癌中的应用

目的探讨超声在冷循环射频治疗肝癌中的应用价值。方法105例肝癌病人,术前利用超声进行评估并据此制定治疗方案,经皮及术中射频治疗均采用超声作为引导方式,术后1周及1月进行超声复查。结果术前超声检查对治疗方案的制定起重要作用。超声也是最常用的射频引导手段。经皮和术中超声引导下射频各有所长,需根据具体情况选择。射频治疗后瘤体二维超声表现多样,部分瘤体坏死液化。能量多普勒提示肝癌的血流信号较术前减少。结论将超声技术紧密结合临床,对射频治疗肝癌病人进行全程干预,有助于冷循环射频成为更安全、更有效的肝癌治疗方法。

APPLICATION OF ULTRASONOGRAPHY IN THE COOL-TIP RADIO-FREQUENCY ABLATION OF HEPATIC NEOPLASM

Objective To evaluate the ultrasonography in the cool-tip radio-frequency ablation of hepatic neoplasms.Methods The pre-operative ultrasound images of 105 cases of hepatic neoplasm werr analyzed,on the basis of which the treatment strategies were established.During the period of procedures including percutaneous or open surgical radio-frequency ablations,ultrasonography was applied as the imaging-guided method.Ultrasound examinations were fulfilled 1 week and 1 month after treatments.Result The preoperative ultrasonography had an important role on the choice of treatment strategies.Without question sonography is the most common method used to guide radio frequency ablation.The advantages and disadvantages of the percutaneous and intraoperative ultrasonography are quite different,which will determine the choice of approach.Although the images of the postoperative cases were variable,the blood flows of the neoplasms werr disappeared or decreased obviously detected by CDE.Conclusion Ultrasonography is a useful method in the cool-tip radio-frequency ablation of hepatic neoplasms.Moreover,the applications of ultrasound in the entire procedure is beneficial to making the cool-tip radio-frequency ablation safer and more effective.
