漏斗胸术后心功能远期随访

摘要

Objective To assess the long-term effects on cardiac function after operative correction of pectus excavatum(PE)in children.Methods Fomy-one children with PE underwent M-mode echocardiogram before and 2-8 years after the corrective operation.Forty-one children whose gender,age and body weight matched with these patients were served as control.Results Preoperative ejection fraction(EF)and velocity of circumferential fibet shortening(MVCF)were significantly lower than those of the controls (P＜0.01),whereas stroke volume(SV)and fractional shortening of the minor semi-axis(FS)showed no difference(P＞0.05).Postoperatively,there was no change in FS,but EF,MVCF and SV increased significantly(P＜0.05)and were comparable to those of the controls(P＞0.05).Conclusions Cardiac function in patients with PE was compromised.It can he gradually restored to normal after correction.%目的 探讨漏斗胸术后心脏功能的变化.方法 用超声心动图测定41例漏斗胸患儿术前、术后的心脏功能,并选择年龄、性别、身高、体重相同的正常儿童作对照.结果 漏斗胸患儿术前射血分数(EF)与平均左心室周径缩短率(MVCF)与对照组相比有降低(P＜0.05),长期随访发现息儿术后EF、MVCF与每搏输出量较术前有上升(P＜0.01),而且这些指标与对照组相比差异无显著性(P＞0.05).结论 漏斗胸术后患儿的心脏功能可恢复正常.
