摘要
目的：探讨256层CT对复杂型先天性心脏病的临床应用价值。方法：回顾性分析59例先天性心脏病患者的256层CT扫描和心彩超资料，与手术和DSA结果进行对照分析。结果：59例经手术或DSA证实的心内、外结构异常共267个，其中心内结构异常132个，心脏与大血管连接部位异常24个，心外大血管异常111个。256层CT和心彩超对心内结构畸形的诊断符合率分别为70.45%和96.97%，差异有显著性意义（P<0.05）；对心脏与大血管连接部分畸形的诊断符合率分别为91.67%和95.83%，差异无显著性意义（P>0.05）；对心外大血管畸形的诊断符合率分别为93.69%和74.77%，差异有显著性意义（P<0.05）；对先天性心脏病总的诊断符合率分别为82.02%和87.64%，差异无显著性意义（P>0.05）。结论：256层CT对心外大血管畸形的诊断优于心彩超，256层CT和心彩超结合更有利于改善复杂型先天性心脏病的术前无创性评估。
Abstract
Objective: To evaluate the value of 256-slice CT in the clinical diagnosis of congenital heart disease. Methods: The 256-slice CT data of 59 patients with complex congenital heart disease(CCHD) were analyzed retrospectively and compared with the findings of echocardiography and surgery. Results: Total 267 intra- and extra-cardiac anomalies were found. Of intra-cardiac anomalies, 70.45% were identified by 256-slice CT while 96.97% of them were detected by echocardiography, with significant statistic difference(P<0.05). 91.67% of the cardiac and great vessels connecting part anomalies were identified by 256-slice CT, while 95.83% were detected by echocardiography, with no significant statistic difference(P>0.05). 93.69% of the extra-cardiac anomalies were identified by 256-slice CT, while only 74.77% were detected by echocardiography, with significant statistic difference(P<0.05). The overall diagnostic accuracy was 82.02% for 256-slice CT and 87.64% for echocardiography, with no significant statistic difference(P>0.05). Conclusion: 256-slice CT is better than echocardiography in the detection of extra-cardiac anomalies of CCHD, 256-slice CT in combination with echocardiography can significantly improve the diagnostic accuracy of CCHD in children.
