先天性心脏和大血管畸形的电子束计算机断层摄影术诊断--与超声心动图的对照研究

目的:探讨电子束计算机断层摄影术(EBT)和超声心动图在先天性心脏和大血管畸形诊断中的价值. 方法:收集34例分别经超声心动图和EBT检查的心脏和大血管畸形诊断资料,其中18例经心血管造影检查证实,21例有手术结果对照.结果:EBT诊断符合率82.4%,超声心动图诊断符合率73.5%.EBT对心外大血管畸形诊断准确率为97.9%,明显优于超声心动图(53.2%).而超声心动图对心内畸形的诊断准确率为95.9%,高于EBT(81.6%).对大血管与心室、房室连接处的畸形二者的诊断准确率基本相同.结论:超声心动图与EBT检查相结合,可明显提高先天性心脏病的诊断准确率,减少有创的心血管造影检查.

Diagnosis Values of Electron Beam Tomography and Echocardiography in Complex Congenital Heart Disease

Objective:To inve tigate the value o electron beam tomography and echocardiography or diagno ing the comple congenital heart di ea e . Method :Thirty our patient with comple congenital heart di ea e underwent both echocardiography and electron beam tomography,which wa con irmed by angiocardiography in 18 patient .Twenty one patient were operated on.All data were comparatively analyzed Re ult :The rate o diagno i coincidence in diagno ing comple congenital heart di ea e wa 82 4% or electron beam tomography,and 73 5% or echocardiography.The accuracy o electron beam tomography in diagno ing e tracardiac abnormal tructure wa 97 9% and obviou ly higher than 53 2% by echocardiography.The accuracy o echocardiography in diagno ing intracardiac abnormal tructure wa 95 9% and higher than 81 6% by electron beam tomography.Electron beam tomography and echocardiography had a imilar accuracy or diagno ing abnormal tructure at the junction o ve el with cardiac chamber. Conclu ion:Electron beam tomography combined with echocardiography can greatly improve the diagno i accuracy o comple congenital heart di ea e and can al o reduce the u e o inva ive angiocardiography.
