目的评价Amplatzer封堵器治疗动脉导管未闭(PDA)及房间隔缺损(ASD)的疗效。方法将12例PDA、4例ASD于X线透视和经胸超声心动图(TTE)监视下置入Amplatzer封堵器。术后复查TTE及X线检查。结果16例封堵器置入均获成功,成功率100%,术后24hTTE显示2例(12.5%)存在残余分流,分别于72h、1周后分流消失。随访6个月,TTE检查无残余分流,X线胸片示肺血流量减少。结论采用Amplatzer封堵器治疗PDA及ASD安全有效、操作简便、成功率高。
Objective To evaluate the efficacy of Amplatzer occluder in the treatment of patent ductus arteriosus (PDA) and atrial septal defect (ASD). Methods 12 cases of PDA and 4 cases of ASD were placed into Amplatzer occluder under X-ray and transthoracic echocardiography (TTE). Postoperative review of TTE and X-ray examination. Results All the occluders were successfully implanted in 16 cases, with a success rate of 100%. Twenty-four patients (12.5%) had residual shunt at 24hTTE, and shunt disappeared at 72h and one week respectively. Followed up for 6 months, TTE examination without residual shunt, X-ray showed pulmonary blood flow decreased. Conclusion The Amplatzer occluder is safe and effective in treating PDA and ASD. The operation is simple and the success rate is high.
