摘要

目的：研究16层螺旋CT（MSCT）及其三维重建在先天性心脏病（简称先心病）心外大血管畸形中的应用价值。方法：对26例手术证实的先心病患者心外大血管畸形进行分析，所有病例均行MSCT增强扫描，随后在工作站进行三维重建，并与26例经胸超声心动（UCG）及13例心血管造影（CAG）结果进行对比。结果：手术证实心外大血管畸形83处，其中心脏大血管连接处畸形20处，完全大血管畸形63处，MSCT、UCG、CAG诊断准确率分别为98.8%、89.2%、100%，MSCT及CAG诊断准确率与UCG诊断准确率有显著性差异（χ2=4.76，P<0.05）；（χ2=4.11，P<0.05），MSCT与CAG诊断准确率无显著性差异（χ2=0.43，P>0.05）。结论：MSCT及其三维重建对先心病心外大血管畸形诊断明显优于UCG，且成像速度快，可以清晰显示心外大血管的病理解剖结构，对于临床术前评估、选择术式是一种很好的无创检查方法，MSCT与UCG联合应用在很大程度可以取代有创CAG检查。

Abstract

Objective: To study the value of 16-slice helical CT(MSCT) and three-dimensional(3D) reconstructions in the diagnosis of extracardial vascular deformities in patients with congenital heart disease(CHD). Methods: To analyse extracardial vascular abnormalities in 26 patients confirmed by surgery. All patients were examined by contrast-enhanced MSCT and subsequent 3D reconstruction at work-station. Correlative evaluations were performed with 26 echocardiograms(UCG) and 13 cineangiocardiograms(CAG). Results: Eighty-three extracardial vascular abnormalities were confirmed. The denifite rate of diagnosis of MSCT, UCG and CAG were 98.8%, 89.2%, 100% respectively. MSCT and CAG were superior to UCG in the identification of extracardial vascular abnormalities（χ2=4.76, P<0.05）; (χ2=4.11, P<0.05）, the diagnostic accuracy of MSCT and CAG showed no difference（χ2=0.43, P>0.05）. Conclusions: MSCT(short acquisition time of image) with 3D reconstruction were superior to UCG for the assessment of extracardial vascular abnormalities in patients with CHD and could demonstrate the pathological morphology. This combination was a good noninvasive diagnostic way in preoperative evaluation and selecting operative modality. The combination of MSCT and UCG was a substitution for invasive CAG in great extent.
