多层螺旋CT和经胸二维超声心动图检查在先天性心脏病诊断中的意义

Multislice spiral computed tomography in detecting congenital heart diseases in children.

目的探讨多层螺旋CT(MSCT)及联合经胸二维超声心动图(TTE)检查在先天性心脏病诊断中的意义。方法收集广东省心血管病研究所自2002年9月至2003年12月间86例儿童先天性心脏病病例,全部患儿接受了MSCT和TTE检查,12例接受心导管检查,其中69例进行了外科手术,将术前MSCT、TTE和心导管检查结果分别与手术诊断进行比较。结果69例患儿共计有129处畸形,TTE正确诊断116处(89.9%),MSCT正确诊断112处畸形(86.8%),两者联合正确诊断127处畸形(98.4%),12例心导管检查未能提供更有价值的资料。结论MSCT对先天性心脏病诊断具有较高的价值,尤其是联合TTE可取代部分心导管检查为外科手术提供正确和充分的术前诊断。对于年龄小或重症不耐受心导管检查的患儿具有更大的意义。

Objective To evaluate the effectiveness of multislice computed tomography (MSCT) in diagnosis of congenital heart diseases in children.Methods 86 patients were involved.69 had been performed operations.The preoperative results of transthoracic two dimensional echocardiography (TTE),MSCT and angiocardiography were compared with those of surgery.Results Of the totally 129 malformations,TTE had correctly revealed 116 (90%),MSCT 112(86.8%),and both combined had correct diagnosis for 127(98.4%).Angiocardiography in 12 patients had not provided further information. Conclusion MSCT is a valuable additional diagnosis tool in congenital heart diseases,especially when combined with TTE.They might take place some of the angiocardiography before surgery.
