目的 探讨彩色多普勒超声心动图（ＣＦＭ）诊断新生儿青紫型先心病的可行性和优越性。方法 应用ＣＦＭ 探查新生儿青紫型先心病１０６ 例，按超声顺序分段探查法确定先心病的类型。结果 完全性大动脉转位４４ 例（４１－５ ％）居本组首位；肺动脉闭锁２３ 例（２１－７％ ）居第２ 位；危重型法乐四联症１６ 例（１５－１％ ）居第３ 位；完全性肺静脉异位引流８ 例（７－５％） 居第４ 位；极重型肺动脉瓣狭窄５ 例（４－７ ％）居第５ 位；左心发育不良综合征４ 例（３－８ ％） 居第６ 位；其他包括三尖瓣闭锁２ 例（１－８ ％）；三尖瓣下移畸形、永存动脉干、左心室双出口、纠正型大动脉换位各１ 例，均占０－９％ 。结论 ＣＦＭ 不仅安全无创且诊断准确率高，是临床评价新生儿青紫型先心病的首选无创性检查手段。
Objective To investigate the feasibility and superiority of color Doppler echocardiography (CFM) in the diagnosis of neonatal cyanotic congenital heart disease. Methods 106 cases of neonatal cyanotic congenital heart disease were detected by CFM. The type of congenital heart disease was determined by sonographic sequential sub-exploration. Results Complete transposition of the great arteries occurred in 44 cases (41-5%) in the first place in this group; pulmonary atresia in 23 cases (21-7%) ranked No. 2; and severe type tetralogy of Fallot in 16 cases (15-1%) (7-5%) were in the fourth place; extreme pulmonary valve stenosis in 5 cases (4-7%) ranked No. 5; left heart hypoplasia syndrome in 4 cases (7-5% 3-8%) ranked No. 6; others included tricuspid atresia in 2 (1-8%); tricuspid valve deformity, perpetual survival of the arteries, left ventricular double outlet, the correction of aortic transposition in 1 case, All account for 0-9%. Conclusion CFM is not only safe and noninvasive but also has a high diagnostic accuracy. It is the first choice of noninvasive method for evaluating neonatal cyanotic congenital heart disease.
