老年房间隔缺损病人的手术治疗

目的总结老年房间隔缺损病人手术治疗经验。方法对12例60岁以上继发孔型房间隔缺损病人进行手术治疗,年龄为60～66岁,平均(62.3±2.4)岁,全部合并三尖瓣关闭不全,其中还合并二尖瓣关闭不全10例;房颤9例,房扑1例;术前采用右心导管进行肺动脉测压,肺动脉平均压为(5.31±3.12)kPa,最高为8.4kPa。本组房缺修补采用心包片或涤纶补片修补,同期行三尖瓣成形术12例,其中3例行Kay’s二叶瓣成形术,9例行Devage成形术;二尖瓣成形术6例,二尖瓣置换术2例,3例合并有房颤者同期行右房迷宫术。结果12例病人术后全部存活,心功能均有明显改善,但与其他年龄组手术病人比较,术后多巴胺使用时间和住院时间明显延长,6例发生胸腔积液,术后随访3～60个月。结论老年房缺病人修补手术成功的关键在于合并症的同期手术处理和手术后的心功能支持。

Surgical treatment of isolated atrial septal defect secundum in the elderly

Objective To review the clinical experiences of surgical treatment of isolated atrial septal defect secundum in elderly patients. Methods 12 patients were over 60 years of age (range, 60～ 66, with a mean of 62.3 years). Coexislent disorders were moderate to severe tricuspid regurgitation in all 12 patients, mitral valve regurgitation in 10, atrial fibrillation in 9 and atrial flutter in 1. Preoperative mean pulmonary artery pressure in these 12 patients was 5.31 + 3.12 kPa. All patients underwent closure by Dacron and pericardial patch. 12 patients underwent either De vage or Kay tricuspid annuloplasty for TVR, and 6 mitral valve repair, 2 mitral valve replacements. Three patients with atrial fibrillation underwent right-sided maze procedure. Results All patients survived the operation, heart function being improved in most patients. Conclusion Old age is not a contradiction to repair of atrial septal defect. The key element in successful operation relies on concomitent correction of the coexisted disease and postoperative cardiac support.
