摘要
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 3 4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 ,2 1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 (5 3 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。
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.
