目的 探讨漏斗胸微创矫治矫形板取出后,胸廓形状的再次重塑及疗效.方法 矫治患者145例,男115例,女30例;成人59例,儿童86例.采用改进微创技术,由同一手术组完成;术后12~82个月取出矫形板.评价取出矫形板前和后1、12个月疗效,评价指标为胸廓外观、胸廓指数、胸部CT影像和CT矢状位测量胸骨后至脊柱前缘间的距离.结果 胸廓形状良好.胸廓指数:取矫形板前,儿童2.36±0.32,成人2.60 ±0.45;取矫形板后,儿童2.77±0.44,成人3.04±0.56.取出矫形板前后比较,胸骨均有所下沉,以胸骨体下端下降最多,儿童(15.18 ±7.95)mm,成人(14.93 ±8.81)mm,取板前、后差异有统计学意义.心脏均无受压征象.在不影响胸廓发育的前提下,矫形板取出时间以儿童3年、成人5年为宜.结论 漏斗胸矫治后经过一定间期再取出矫形板,胸骨有所下沉;但胸廓重塑后,胸廓形状饱满,未再发生心肺受压表现.
Objective To study thoracic re-remodeling and therapeutic effect after the bar removal for pectus excavatum corrected by minimal-invasive technique.Methods 145 cases with pectus excavatum,male 115,femal 30;adults in 59,children 86;corrected by minimal-invasive technique improved and performed by the same group surgeon.Bar removed 12-82 months after the procedure,appraising index of curative effects include in chest appearance,thoracic index,thoracic computer tomography(CT) and the distance between the behind of sternum to the anterior border of thoracic spine in the sagittal view.Results The chest shape was good.Thoracic index:before bar removal 2.36 ± 0.32 in children,2.60 ± 0.45 in adults;after that,2.77 ± 0.44 in children,3.04 ± 0.56 in adults.There was all subsidence on the each point of the sternum,descent the maximum at the inferior end of the midsternum,(15.18 ±7.95)mm in children,(14.93 ± 8.81) mm in adults,comparing with bar removal before and after.There was statistical significance.Not the signs of compressing the heart on the CT view.The time interval of the bar removed 3-year in children,5-year in adults without affecting the development of the patients' thorax.Conclusion The sternum descended slightly after bar removal when pectus excavatum corrected to expecting effects.After that,thoracic remodeling again,the chest shape well.
