目的探讨64排CTA对小儿先天性心脏病的诊断价值及后处理重建方法。方法收集整理郑州市儿童医院2010年4月-2012年3月期间经64排心脏CTA检查患儿的临床及CT资料并进行分析,总结小儿先天性心脏病64排CTA后处理诊断方法。结果 73例经64排CTA检查的先天性心脏病患儿均能明确诊断,其中复杂先心病40例,有房间隔缺损者17例,有室间隔缺损者43例,有动脉导管未闭者7例,有肺动脉狭窄者5例,先天性肺动脉闭锁1例,有右室流出道狭窄者22例,有肺静脉异位引流者3例,有主动脉狭窄者2例,永存左上腔静脉4例,右位主动脉弓3例。与彩超及手术结果比较差异无统计学意义。结论小儿先天性心脏病的64排CTA扫描及后处理重建,对先天性心脏病能够作出明确诊断,图像直观细腻逼真,具有较强的实用价值。
Objective To investigate the diagnostic value of 64-row CTA in children with congenital heart disease and the methods of post-treatment reconstruction. Methods The clinical data and CT data of 64 children with CTA from April 2010 to March 2012 were collected and analyzed in Zhengzhou Children’s Hospital from April 2010 to March 2012, and the diagnostic methods of 64-row CTA post-treatment in children with congenital heart disease were summarized. Results 73 cases of congenital heart disease by 64 CTA examination can be diagnosed in children, including 40 cases of complicated congenital heart disease, atrial septal defect in 17 cases, ventricular septal defect in 43 cases, with patent ductus arteriosus 7 Cases, pulmonary stenosis in 5 cases, 1 case of congenital pulmonary atresia, right ventricular outflow tract stenosis in 22 cases, 3 cases of pulmonary venous drainage, 2 cases of aortic stenosis, 4 cases of permanent left superior vena cava, Right aortic arch in 3 cases. And color Doppler ultrasound and surgical results showed no significant difference. Conclusion 64-slice CTA scan and post-processing reconstruction of children with congenital heart disease can make a clear diagnosis of congenital heart disease, and the images are vivid and vivid, with strong practical value.
