摘要:

目的 探讨介入治疗房颤消融术后严重肺静脉狭窄的可行性、有效性及安全性。方法 回顾性分析7例介入治疗房颤消融术后严重肺静脉狭窄的临床资料。介入治疗过程中先行肺小动脉造影及肺静脉造影,显示4支肺静脉回流途径,确定肺静脉狭窄的数量、位置及程度,最后行肺静脉狭窄球囊扩张术及支架术。结果 7例患者介入治疗均获成功,术后所有患者症状改善,肺静脉狭窄程度减轻,肺动脉压力下降,活动耐量提高,心功能好转。结论 介入治疗房颤消融术后严重肺静脉狭窄安全有效。

Abstract:

Objective To investigate the feasibility, efficiency, and safety of interventional therapy for severe pulmonary vein stenosis after radiofrequency ablation of atrial fibrillation. Methods The clinical data of seven cases of severe pulmonary vein stenosis after radiofrequency ablation of atrial fibrillation were retrospectively analyzed. During the course of interventional therapy, the small pulmonary arteriography and pulmonary phlebography were conducted first to detect the circumfluence path of four pulmonary veins and to determine the number, location, and extent of pulmonary vein stenosis, and then the balloon and stent technique were used to treat the stenosis. Results The interventional therapy of seven cases was successful and symptoms of all patients were improved after operation. The degree of pulmonary vein stenosis reduced; the pressure of pulmonary artery lowed; and the activity tolerance and heart function improved. Conclusion The interventional therapy is a safe and effective method for the treatment of severe pulmonary vein stenosis after radiofrequency ablation of atrial fibrillation.
