冷冻球囊导管消融术的临床疗效及安全性分析

The analysis of clinical efficacy and safety by cryoballoon catheter ablation surgery

目的 评价冷冻球囊导管消融术的临床疗效及安全性.方法 选择2014年6月至2015年6月华中科技大学附属同济医院就诊的38例阵发性房颤患者,采用冷冻球囊技术进行房颤消融治疗.结果 房颤消融手术平均时间（125.5±38.2）min,平均透视时间（27.4±13.0）min,平均冷冻消融时间（36.9±12.8）min,导管消融即时成功率92.7％,平均每根肺静脉冷冻次数2-6（4.0±1.2）次/根.各肺静脉即时成功率：左上肺静脉95.3％,左下肺静脉92.5％,右上肺静脉93.2％,右下肺静脉89.7％.术中行右上肺静脉消融时,并发膈神经麻痹1例,发生率2.6％;术后回访,1例患者12个月内复发,复发率3％.结论 冷冻球囊消融术安全性高,具有良好的临床疗效.

Objective To evaluate the cryoballoon catheter ablation surgery clinical efficacy and safety.Methods Selected 38 patients with paroxysmal atrial fibrillation by the cryoballoon catheter ablation surgery for atrial fibrillation ablation between June 2014 to June 2015 in Tongji hospital affiliated to Huazhong university of science and technology.Results Of atrial fibrillation ablation procedures the average time （125.5 ± 38.2）min,average fluoroscopy time （27.4± 13.0）min,average cryoablation time （36.9± 12.8）min,catheter ablation immediate success rate of 92.7%,the average pulmonary veins freezing times 2-6 （4.0±1.2）beats/root.Each pulmonary vein immediate success：left superior pulmonary vein was 95.3%,lower left pulmonary vein 92.5%,right superior pulmonary vein 93.2%,right inferior pulmonary vein 89.7%.When intraoperative right superior pulmonary vein ablation,merge one phrenic nerve palsy patient,the incidence was 2.6%;one patient relapsed from return visit within 12 months after surgery,the recurrence rate was 3% in.Conclusion The cryoballoon catheter ablation surgery is safe,and has a good clinical efficacy.
