射频消融技术联合DSA引导下无水乙醇介入治疗口腔颌面部难治性动静脉畸形的疗效观察

目的 探讨射频消融技术联合数字减影血管造影（digital subtraction angiography,DSA）引导下无水乙醇介入治疗难治性口腔颌面部动静脉畸形的可行性,评价其临床疗效及安全性。方法 2014年3月—2016年4月,应用射频消融技术联合DSA引导下无水乙醇介入栓塞治疗7例口腔颌面部动静脉畸形患者（男4例,女3例）,密切随访,根据患者的临床症状、不良反应、并发症以及影像学资料的变化进行疗效观察及评价。结果 6例有效,1例无效,治疗有效率为85.7%。未观察到严重并发症发生。结论 射频消融技术联合DSA下无水乙醇介入栓塞治疗难治性口腔颌面部动静脉畸形的近期疗效及安全性良好,可能成为其重要的治疗方式。

Effect of radiofrequency ablation combined with DSA-guided percutaneous ethanol sclerotherapy for refractory arteriovenous malformations in oral and maxillofacial region

PURPOSE : To evaluate the clinical effect and safety of radiofrequency ablation (RF) combined with digital subtraction angiography (DSA) -guided percutaneous ethanol sclerotherapy for refractory arteriovenous malformations(AVMs) in oral and maxillofacial region and to investigate its feasibility. METHODS : A retrospective review of patients, medical and imaging records was performed. Seven patients (4 males,3 females) with craniofacial arteriovenous malformations underwent staged RF combined with DSA-guided percutaneous ethanol sclerotherapy between March 2014 and April 2016. RESULTS : Six of 7 patients were cured,1 had no response. The therapeutic outcome was considered effective in 6 patients (85.7%). No major complications occurred. CONCLUSION S: RF with percutaneous ethanol sclerotherapy under DSA has the potential for curing refractory AVMs in oral and maxillofacial region, which may become an effective and safe tool for AVM management.
