摘要
目的探讨超声和320排CT联合诊断复杂先天性心脏病的价值。方法回顾性分析68例复杂先天性心脏病患者手术发现的184处畸形，并将畸形分为心内结构、心脏大血管连接部及心外大血管畸形3组。所有患者术前均行超声心动图及CT检查。与手术结果对比，分析超声及CT各自漏误诊情况。结果与手术结果对比，CT与超声诊断心内结构畸形漏误诊率分别为12％（11／93）、1％（1／93）；心脏大血管连接部位畸形漏误诊率分别为4％（2／49）、6％（3／49）；心外大血管畸形漏误诊率分别为2％（1／42）、19％（8／42）；对所有畸形漏误诊率分别为8％（14／184）、7％（12／184）。超声与CT联合诊断所有畸形漏误诊率为1％（2／184）。两影像学方法对比，心内结构、心外大血管畸形两组差异有统计学意义（P〈0．05）；心脏大血管畸形组差异无统计学意义（P〉O．05）。两影像学方法对所有畸形的漏误诊率差异无统计学意义（P〉0．05）。结论超声和CT在诊断复杂先天性心脏病中各有优势和不足，联合应用可明显减少术前诊断漏诊、误诊率。
Objective To investigate the application of transthoracic echocardiography （TTE） and 320-row CT in diagnosis of complex congenital heart disease（CCHD）. Methods A retrospective analysis was performed in 68 patients with CCHD, which contained the echocardiographic apprarance,320-row CT and surgical outcoming. All of malformations were divided into three groups：intracardiac group, heart-large vascular connecting group and extracardiae group. Results One hundred and eighty-four malformations were comfirmed by surgery in the 68 cases. The misdiagnosis and missed diagnosis rate of CT and TTE：for the intracardiac anomalies were 12% （11/93）, 1%（1/93） respectively （ P d0.05）, for the heart-large vascular connecting malformation were 4% （2/49）, 6% （3/49） respectively （ P 〉 0.05）, and for the extracardiac anomalies were 2% （ 1/42）, 19% （8/42） respectively （ P 〈 0.05）, for the total anomalies were 8%（14/184）,7% （12/184） respectively （P〈0. 05）. While it was 1% （2/184） in diagnosis of total anomalies by both CT and TTE. Conclusions Both 320-row CT and TTE have their own advantages and shortcomings in the diagnosis of CCHD. Joint application of two methods could reduce the rate of misdiagnosis and missed diagnosis of CCHD.
