目的 探讨超声与CT联合应用在 复杂先天性心脏病中的诊断价值。方法 选取我院2012年5月-2017年5月收治的复 杂先天性心脏病患者86例为研究对象，均 经手术病理证实，且术前进行超声及CT检 查。比较分析手术诊断与超声、CT以及二 者联合检查诊断结果。结果 本组患者经 手术证实，心脏畸形共有217处，包括心 脏大血管连接处结构异常66处，心内与 房室连接处结构异常112处，心外大血管 结构异常39处。超声检查共检出196处， 诊断准确率为90.32%；CT检查共检出197 处，诊断准确率为90.78%；超声与CT联合 检查共检出211处，诊断准确率97.24%， 二者联合诊断的准确率明显高于单纯超声 及单纯CT诊断准确率，分别比较差异有统 计学意义(P<0.01)。结论 超声和CT在复 杂先天性心脏病诊断中各有优势和不足， 二者联合检查可实现优势互补，显著提高 诊断准确率；同时，该检查方式无明显侵 入性、费用较低，有较高的临床应用价 值。

Objective To explore the diagnostic value of ultrasound and CT in complex congenital heart disease. Methods 86 patients with complex congenital heart disease were selected as the study subjects in our hospital from May 2012 to May 2017, who were confirmed by surgical pathology and preoperative ultrasonography and CT examination were performed. To have a comparative analysis of surgical diagnosis and ultrasonography, CT and the combination of the two diagnostic results, respectively. Results This group of patients confirmed by surgery, a total of 217 heart deformities, the structure of the coronary artery was 66, and the structure of the atrioventricular junction was 112, and the large vascular structure of the heart was 39. Ultrasound detected 196 heart deformities, the diagnostic accuracy rate was 90.32%. CT examination detected 197, the diagnostic accuracy rate was 90.78%; the combined use of ultrasound and CT combined examination detected 211, the diagnostic accuracy rate was 97.24%, the accuracy of the combined diagnosis was significantly higher than that of ultrasound or CT alone, the difference was statistically different (P<0.01). Conclusion Ultrasound and CT in the diagnosis of complex congenital heart disease have their own advantages and disadvantages, the two ways combined can achieve complementary advantages, significantly improve the diagnostic accuracy, at the same time, the inspection method is not invasive, costless, and have high clinical application value.
