经皮射频毁损治疗肝海绵状血管瘤的临床疗效分析

目的探讨实时超声引导下经皮射频消融治疗肝海绵状血管瘤的临床疗效。方法对19例共22个肝海绵状血管瘤病灶行超声引导下经皮射频消融治疗,分层多点或多次叠合消融治疗55点,平均每例行2.9点。结果 19例患者随访6~96个月,平均随访(44±28)个月。经一次治疗完全缓解(CR)16例,部分缓解(PR)3例,缓解率(CR%+PR%)达100%。病灶直径平均缩小79.8%(80.2%~92.1%),患者平均住院天数8.8天。结论应用实时超声引导下经皮射频消融对肝海绵状血管瘤治疗具有微创、有效、安全等特点,是治疗肝海绵状血管瘤的一种理想方法。

Evaluation of clinical efifcacy of percutaneous radiofrequency ablation for hepatic cavernous hemangioma

Objective To explore clinical effect of real-time ultrasound-guided percutaneous radiofrequency ablation hepatic cavernous hemangioma. Methods Ultrasound-guided percutaneous radiofrequency ablation was conducted 22 lesions in 19 patients with hepatic cavernous hemangioma were given multiple over lapping ablation （55 RFA sessions, average 2.9 sessions per patient）. Results Follower-up observation in 19 patients for 6-96 （44 ＆#177; 28） months showed a complete response in 16 patients and a partial response 3 patients by one mission of percutaneous radiofrequency ablation, effective rate （CR% ＋ PR%） being 100%. The hepatic cavernous hemangiomas decreased by a mean of 79.8%（80.2%-92.1%） in diameter. The average length of stay was 8.8 days. Conclusions PRFA has characteristic of minimally invasion, safeness and effective therapy for HCH in properly selected patients by experienced hands.
