目的 :评价 0 0 5 2Gianturcocoil弹簧栓子经导管封堵动脉导管未闭 (PDA)的疗效及安全性。方法 :10例PDA患者在基础和骶管麻醉下 ,用心内膜心肌活检钳控制和传递 0 0 5 2Gianturcocoil弹簧栓子 ,顺行经导管封堵PDA。结果 :8例 1枚Gianturcocoil弹簧栓子、1例 3枚Gianturcocoil弹簧栓子完全封堵成功 ,1例因Gianturcocoil弹簧栓子未能回收至传递鞘内改行手术结扎。结论 :用 0 0 5 2Gianturcocoil弹簧栓子经导管封堵 3 0～ 4 0mm直径的PDA ,是安全、可靠的非手术方法 PURPOSE: To evaluate the efficacy and safety of 0 0 5 2 Gianturcocoil spring embolus for catheterization of patent ductus arteriosus (PDA). Methods: Ten patients with PDA underwent basic and caudal anesthesia with endocardial biopsy forceps to control and deliver 0 0 5 2  Gianturcocoil spring emboli. Results: One case of Gianturcocoil spring emboli in 8 cases and one case of 3 Gianturcocoil spring emboli were completely blocked. One case was failed to be repaired by the Gianturcocoil spring embolus until the transsection was performed. CONCLUSIONS: The use of 0 0 5 2  Gianturcocoil spring emboli for catheterization of 30 to 40 mm diameter PDA is a safe and reliable non-surgical method
