经导管膜部心室间隔缺损介入封堵术

The transcatheter closure of perimembraneous ventricular septal defect using asymme tric membraneous VSD device

目的 :为评价经导管膜周部室间隔缺损 (perimembraneousventricularseptaldefect,PVSD)封堵术可行性 ,本文报告经导管用新型Amplatzer封堵器封堵PVSD临床经验。 方法 :2 0 0 2年 6月～ 2 0 0 3年 6月 ,诊断 32例PVSD。结果 :32例患者中除一例因VSD膜部瘤松软未能成功置入外 ,其余患者均能正确置放新型Amplatzer封堵器和即刻完全封堵PVSD。术后 2 4h至 6月用TTE复查 ,所有患者被完全封堵。结论 :经导管用新型Amplatzer封堵器封堵PVSD是一种非常有效的可行的非开胸方法。本组技术成功率为 97%。

Objective:To evaluate the feasibility of transcatheter closure of Perimembraneous Ventricular Septal Defects (PVSD). This paper, however, is to report on our clinical experience using Asymmetric membraneous VSD Amplatzer Occluder Device(AAOD). Methods:Between June in 2002 to June in 2003, PVSD for 32 patients was diagnosed. Results:The device was correctly placed in 32 patients except 1 case with soft aneurysm of perimembraneous VSD. There was immediate and complete closure of PVSD in 31 patients. TTE showed there was complete closure of the PVSDs in 31 patients from first day to 6 months after operation. Conclusion:Transcatheter closure of PVSDs using asymmetric perimembraneous VSDs Amplatzer occluder device was an excellently efficient, feasible nonsurgical method. The successful rate of technique was for 97% in this group.
