室间隔缺损修补术后中远期主动脉瓣关闭不全的外科治疗分析

目的:探讨室间隔缺损(VSD)修补术后中远期主动脉瓣关闭不全(AI)的外科治疗方法.方法:总结1996-01至2007-12我院22例VSD术后AI的外科治疗经验.主动脉瓣病变以穿孔为主,本组主动脉瓣置换13例,主动脉瓣成形9例.结果:22例患者中手术死亡1例.出院检查与术前比,心胸比率(0.52±0.04 vs 0.57±0.07,P<0.05)及左心室舒张末径(46.7±5.8)mm vs(54.5±10.2)mm,P<0.05 ]均有明显缩小,差异有统计学意义.超声心动图检查3例患者主动脉瓣少量反流,余未见明显异常.结论:本病的主要原因可能为手术损伤造成,外科治疗效果满意.

Intermedial to Long Term Surgical Management in Aortic Valve Insufficiency After Ventricular Septal Defect Repair

Objective:To explore the intermedial to long term surgical management in aortic valve insufficiency(AI)after ventricular septal defect(VSD)repair.Methods:A total of 22 consecutive patients with AI after VSD repair in our hospital from January 1996 to December 2007 underwent surgical treatment were enrolled in this study. Valve perforation was mainly pathological changes. Aortic valve replacement was performed in 13 patients and aortic valvuloplasty was done in 9 patients.Results:One patient died after the operation.Post operative X-ray and echocardiogram revealed that both cardio-thoracic ratio(0.57±0.07 vs. 0.52±0.04 P<0.05)and left ventricular end diastolic diameter(54.5±10.2 mm vs. 46.7±5.8mm P<0.05)decreased markedly. 3 patients suffered from mild aortic regurgitation after valvuloplasty.Conclusion:The iatrogenic injury of aortic valve during VSD repair could be corrected satisfactorily by valve replacement or valvuloplasty.
