儿童先天性心脏病心血管造影检查技术

目的 探讨和评价儿童先天性心脏病心血管造影技术。方法 11045例儿童先天性心脏病患者做了心血管造影检查，采用的设备包括早期的快速换片心血管造影设备，电影心血管造影设备和数字减影心血管造影设备。使用了不同的心血管造影技术。结果 用快速换片心血管造影设备和常规正侧位投照时的儿童先天性心脏病心血管造影诊断符合率为80．5％，用电影心血管造影设备和轴位成角投照技术时的造影诊断符合率为90．0％，采用数字减影心血管造影设备，轴位成角投照技术和非离子型对比剂时的造影诊断符合率为96．5％。结论 对于儿童先天性心脏病心血管造影而言，使用动态电影摄片，作数字血管减影，采用轴位成角投照技术，使用非离子型对比剂和快速注射对比剂是取得高质量图像和理想诊断效果的关键。

Angiocardiographic technique of congenital heart disease in children

Objective To evaluate different angiocardiographic techniques of congenital heart disease in children. Methods 11045 pediatric patients with congenital heart disease were performed angiocardiography using cut film, cine film and digital subtraction angiography(DSA) equipments. Different angiocardiographic techniques were used. Results The diagnostic accuracy of cut film with conventional AP and lateral views was 80.5%,the diagnostic accuracy of cine film with angulated views was 90.0% and the diagnostic accuracy of DSA using non-ionic contrast medium with angulated views was 96.5%. Conclusion Dynamic picture angiography with digital subtraction using non-ionic contrast medium under rapid injection is the key for claiming the high quality imaging diaguosis of congenital heart disease in children.
