【摘要】 目的　探讨三维超声导向射频治疗肝癌的临床价值。方法　应用三维超声导向对 3 0例肝癌患者的 42个肿瘤结节进行射频治疗。在三维声像图下 ,可见穿刺针尖在肿瘤内呈“伞形”散开 ,用 80 10 0W的功率烧灼 10 3 0min ,由深至浅多点多次 ,覆盖整个病灶及周围 6 10mm的正常组织 ,对 <5cm的肿瘤 ,一般 1 3次重叠烧灼 ,>5cm的肿瘤根据病人身体状况 ,至少 4 8次以上重叠烧灼。结果　三维超声导向穿刺成功 2 8例 ( 78% 99% ) ;射频治疗后有 2 5例( 65 % 94% )的肿瘤血供减少 ,随着肿瘤血流减少肿块大小也有不同程度缩小 ,而血供减少不明显者肿瘤缩小也不明显。结论　三维超声导向射频治疗肝癌成功率高 ,能较好地判断穿刺针与肿瘤的位置和布针情况 ,是一种有效的微创治疗方法 ;彩色多普勒可即时检测肿瘤治疗中血供的变化 ,对评价射频治疗肝癌的疗效具有临床价值。更多还原

【Abstract】 Objective To study the clinical value of three dimensional ultrasound-guided radiofrequency ablation in the treatment of heptocarcinoma. Methods Thirty patients with 42 lesions received three dimensional ultrasound-guided radiofrequency thermal ablation at 80W～100W for 10～30 min. Tumors with a diameter of less than 5 cm were ablated for one to three times and those with a diameter of longer than 5 cm were ablated for four to eight times. Results Tumors were successfully punctured and ablated in 28 cases. The blood supply of the tumors was decreased and the tumors were reduced in 25 cases. Conclusion Tumors can be successfully located and punctured under the guidance of three-dimensional ultrasonic Doppler system and radiofrequency thermal ablation is effective in the treatment of hepatic tumors.更多还原
