摘　　要：目的　应用Amplatzer封堵器治疗先天性动脉导管未闭 (PDA)并评价其即刻及短期疗效。方法　 5例患者 ,男 2例 ,女 3例 ,年龄 6-2 7(18.40± 7.2 3 )岁 ,经临床、X线、超声心动图初诊为PDA ,并经术中造影证实 ,测量PDA最窄处内径 ,选择适当型号的输送鞘及封堵器 ,封堵缺损处。术后即刻杂音听诊及 2 4小时后超声心动图复查以评价疗效。结果　造影测量PDA最窄直径为 4-7(5 .2 0± 1.16)mm ,选择封堵器直径为 8-18(12 .80± 3 .2 5 )mm。手术全部获得成功。 4例杂音当场完全消失 ,术后 2 4小时及 1月复查超声心动图亦未见分流 ;1例存留不足 2级的收缩期杂音 ,术后超声心动图见微量残存分流 ,1月后复查残存分流消失。结论　Amplatzer封堵器治疗动脉导管未闭安全、有效、创伤小 。Objective:To assess the immediate and short-term effect of the procedure on patients with patent ductus arteriosus(PDA) using Amplatzer duct occluder(ADO). Methods: All patients(5cases, including 2 male and 3 female)aging from 6-27(18.40±7.23)years were proved PDA by physical examination, X-ray, echocardiography and angiography. The right size ADOs and long sheathes were chosen by the diameter of PDA mensured at its narrowest segment to occlude PDA. The effect was assessed by residual murmur and shunt showed on echocardiography at 24h after the procedure. Results: The mean diameter of PDAs was 4-7(5.20±1.16)mm, and that of the occluders used was 8-18( 12.80±3.25)mm. All procedures are successful. 4 patients had no residual murmur and shunt. One remain less 2 stage systolic murmur and a small residual shunt measured by echocardiography which disappeared after 1 month. Conclusion: Transcatheter occlusion of PDA by Amplatzer duct occluder is an effective and safe procedure with mini damage instead of surgical operation.
