有症状的主动脉缩窄新生儿死亡率很高,这类患儿一半以上伴有室间隔缺损(VSD)或复杂心脏畸形伴VSD.作者报道一组外科手术病儿,并分析肺动脉环缩术对主动脉缩窄治疗效果的影响.方法:64例主动脉缩窄新生儿,年龄1～28天(9±6.3天),按伴有的其他心脏畸形程度不同分成三组.Ⅰ组31例伴有轻度心脏畸形,如小的VSD或房间隔缺损(ASD)等.Ⅱ组18例是伴分流量大的VSD,肺动脉压力高于体循环压力的2/3.Ⅲ组15例是除有VSD外还伴其他心脏复杂畸形,如右室双出口,大动脉错位等.每组病儿观察早期(指手 Symptomatic aortic constriction Neonatal mortality is high, more than half of these children with ventricular septal defect (VSD) or complicated cardiac malformations with VSD. The authors report a group of surgical sick children, and analysis of pulmonary artery ring reduction On the effect of aortic constriction therapy.Methods: 64 newborns with aortic constriction, aged from 1 to 28 days (9 ± 6.3 days), were divided into three groups according to the degree of other cardiac malformations associated with them.Among 31 cases Accompanied by mild cardiac malformations, such as small VSD or ASD, etc .. Ⅱ group of 18 cases with shunt VSD, pulmonary artery pressure higher than the 2 / 3. 3 group of 15 cases except with VSD also accompanied by other complex heart deformities, such as double outlet right ventricle, aortic dislocation, etc. Each group of sick children observed early (finger hand
