MSCT对小儿复杂先天性心脏病的诊断价值

The Diagnosis Value of MSCT for Complex Congenital Heart Disease in Children

目的探讨多层螺旋CT(Multislice Spiral Computed Tomography,MSCT)对小儿复杂先天性心脏病的诊断价值。方法选取2014年到2015年在我院行手术确诊的小儿复杂先天性心脏病患者27例,所有患者术前1个月均经多层螺旋CT和心脏超声(Ultrasound,US)检查,比较两种检查方法对患者心脏畸形确诊率的差异。结果 27例患者共有心脏部分畸形41处,MSCT的确诊率为(39处,95.12%)与US确诊率(40处,97.56%)的差异无统计学意义(χ2=0.346,P=0.556);患者共有大血管部分畸形35处,MSCT确诊率(34处,97.14%)高于US确诊率(27处,77.14%),且差异具有统计学意义(χ2=4.590,P=0.032);患者共有心脏和大血管连接部分畸形35处,MSCT确诊率(34处,97.14%)高于US确诊率(25处,71.42%),且差异具有统计学意义(χ2=8.737,P=0.003);所有患者共有心脏畸形111处,MSCT确诊率(107处,96.40%)高于US确诊率(92处,82.88%),且差异具有统计学意义(χ2=10.913,P=0.001)。结论多层螺旋CT对小儿复杂先天性心脏病心脏畸形的诊断准确率高于心脏超声检查。

Objective To explore the diagnosis value of MSCT for complex congenital heart disease in children. Methods Selected from 2014 to 2015 in our hospital surgery diagnosis of children with complex congenital heart disease in 27 cases, All patients were examined by multi-slice spiral CT and tdtrasound （ultrasound） in I month before surgery. The difference of the two patients was confirmed by the two methods.Results A total of 27 patients with heart rnalformation in 41, the diagnostic rate of MSCT for （39, 95.12%） and US （40, diagnosis rate 97.56%） there was no significant difference （X 2=0-346, P=0.556）. There are a large part of patients with vascular malformation in 35, the diagnosis rate of MSCT （34, 97.14%） higher than the diagnosis rate of US （27, 77.14%）, and the difference was statistically significant （X 2=4-590, P=0.032）. The total number of cardiac and vascular connections was 35, and the diagnostic rate of MSCT （34, 97.14%） was higher than that of US （25, 71.42%）, and the difference was statLstically significant （X 2=8.737, P=0.003）; All patients were cardiac malformation in 111, the diagnosis rate of MSCT （107, 96.40%） higher than the diagnosis rate of US （92, 82.88%）, and the difference was statistically significant （X2=10.913, P=0.001）. Conclusion The diagnostic accuracy of multi-slice spiral CT in children with complex congenital heart disease is higher than that of echocardiography.
