摘要
目的采用CT及心脏超声(UCG)检查评价漏斗胸(PE)患儿手术前后心脏形态的变化。方法选取于我院胸外科接受手术的PE患儿51例,术前、术后均行胸部CT检查,在胸骨凹陷最明显层面测量Haller指数(HI)、心脏指数(CCI)、心脏旋转角(CRA);同时行UCG检查,测量左心室舒张末期前后径(LVD)、右心室前后径(RVD)及左心室射血分数(LVEF),比较各测量和计算值术前、术后的变化及差异,并对各数据与HI行相关性分析。结果 CT的各项指标术前与术后比较差异均有统计学意义(P均<0.05),HI术后下降值为32.78%,CCI下降32.03%,CRA下降14.81%;UCG的术前LVD和RVD与术后比较差异均有统计学意义(P均<0.05),LVD平均值增大8.19%,RVD增大10.35%。CCI和LVD的变化与HI呈正相关(r=0.81、0.33,P<0.05)。结论 CT及UCG均可评价漏斗胸患儿术后心脏形态的改善情况,其中CCI是较客观有效的评价指标。
Objective To evaluate cardiac morphologic changes before and after operation in pectus excavatum children with CT and ultrasound cardiogram （UCG）. Methods Fifty-one pectus excavatum children after operation were enrolled. All the children underwent CT and UCG scan pre-and post-operation. The Haller index （HI）, cardiac compression index （CCI）, cardiac rotation angle （CRA） in CT scans and left ventricle diameter （LVD）, right ventricle diameter （RVD）, left ventricle ejection fraction （LVEF） in UCG were recorded. All the results were compared, and correlation analysis was per- formed between the changes of all parameters and HI. Results HI, CCI, CRA average decreased 32.78%, 32.03%, 14.81% after operation, LVD, RVD increased 8.19%, 10.35X respectively, which had statistical differences between pre-and post-operation （all P〈0.05）. The CCI and LVD had correlation with HI （r=0.81, 0.33, both P〈0.05）. Con- clusion CT and UCG can access the recovery of cardiac shape after operation in pectus excavatum children, and CCI is a suitable evaluation criteria.
