目的:探讨先天性心脏病(先心病)封堵术后残余漏患者于原封堵器内再封堵的可行性及疗效。方法:2002~2005年行介入封堵的431例先心病患者中,术后发生大量残余漏的共3例,其中房间隔缺损(ASD)1例,动脉导管未闭(PDA)2例,均为女性,该3例患者使用的均为早期产的国产封堵器,第1次介入封堵术均成功;术后2年封堵器内有大量残余漏。3例全部再次用国产封堵器封堵的方法处理残余漏。结果:3例均于原封堵器内再置入1枚国产封堵器,成功封堵残余漏。随访6个月~1年,再无残余分流。结论:先心病PDA、ASD介入封堵术后封堵器内大量残余漏患者,采用原封堵器内再封堵这种残余漏处理方法是可行、有效的。
Objective: To investigate the feasibility and efficacy of residual occlusion in patients with congenital heart disease (CHD) after occlusion. Methods: A total of 431 patients with congenital heart disease who underwent occlusion were included in this study. Among them, there were 3 cases with a large residual leak after surgery, including 1 ASD and 2 PDA. For women, the 3 patients used were all early occlusive domestic occluders, and the first occlusion was successful. A large number of residual leaks occured within occluder 2 years after operation. 3 cases all again with domestic occluder blocking method of residual leakage. Results: Three cases were placed in the original occluder and then a homemade occluder, the successful closure of residual leakage. Follow-up of 6 months to 1 year, no residual shunt. Conclusion: There is a great deal of residual leakage in the occluder after the occlusion of PDA and ASD in patients with congenital heart disease. It is feasible and effective to use the residual occlusive device in the original occluder.
