摘要
目的探讨超声心动图和螺旋CT在复杂型先天性心脏病诊断中的价值。方法对97例经临床及经胸超声心动图（TTE）诊断为复杂型先心病的患者进行64排螺旋CT检查，与导管法心血管造影检查和手术结果进行对照。结果97例患者中，TTE诊断符合率90．2％，螺旋CT诊断符合率92．5％，两者比较差异无统计学意义（P〉0．1）；TTE对心内畸形的诊断准确率为99．2％，高于螺旋CT的87．5％，两者比较差异有统计学意义（P〈0．005）；而螺旋CT对心外及大血管与房室连接的诊断准确率为99．0％，优于TTE的78．6％，两者比较差异有统计学意义（P〈0．005）。TTE与螺旋CT两者结合，可将诊断准确率提高为99．1％。结论TTE对复杂型先天性心脏病有重要的诊断价值，尤其对心内畸形诊断准确率高，而螺旋CT对心外及大血管与房室连接关系诊断准确率较高。将TTE和螺旋CT相结合，可大大提高对各种复杂先心病的诊断准确率。
Objective To explore the value of transthoracic echocardiography（TTE）and 64-slice spiral computed tomography（CT） in the diagnosis of complex congenital heart disease（CI-tD）. Methods Ninety-seven patients diagnosed as CHD by TTE underwent 64-slice spiral CT for cardiovascular examination. The results were compared with the results by cardiovascular angiography and from surgery. Results The total diagnosis accordance rated by TEE was 90.2% and that by spiral CT was 92.5%. There was no difference in diagnosis accuracy rate between TTE and spiral CT. The diagnosis accuracy rate in intracardiac defomities by TTE was 99.2% ,higher than 87.50% by spiral CT. However, the diagnosis accuracy rate in extracardiac defomities and ventricular arterial connections was 99.0% by spiral CT, higher than 78.60% by TTE. The combination of TTE and spiral CT can raise the diagnosis accuracy rate to 99.1 0/00. Conclusions TTE is of significant value in complex CHD diagnosis,especially in the diagnosis of intracardiac defomities. The combination of TTE and spiral CT can raise the diagnosis accuracy rate of various kinds of complex CHD.
