小儿房间隔缺损自然闭合的超声随访研究

Follow-Up Research on Spontaneous Closure of Atrial Septal Defects in Newborns with Echocadiography

目的超声随访观察足月新生儿房间隔缺损1岁内的自然闭合情况。方法定期对103例房间隔缺损患者行超声心动图检查,观察患儿缺损口的大小和自然闭合情况。结果 103例房间隔缺损患儿均为继发孔型,经1年随访自然闭合56例。ASD直径3～5 mm者闭合38例,ASD直径5～8 mm者闭合15例,ASD直径8～10 mm者闭合3例。结论超声随访对于新生儿房间隔缺损自然闭合情况的检查具有重要意义。

Objective To observe whether atrial septal defects （ASD） in full-term newborns would spontaneously closed in one year through the follow-up with echocardiography.Methods 103 full-term newborns with ASP were regularly examined with echocardiography to observe the sizes and closure situations of the defects.Results All ASD were secundum type and 56 cases of ASD were determined to be spontaneously closed with echocardiography after one year follow-up. Among the 56 cases of spontaneous closure, there were 38 cases with the diameter of ASD range from 3 mm to 5 mm, 15 cases with the diameter of ASD range from 5 mm to 8 mm and 3 cases with the diameter of ASD range from 5 mm to 8 mm. There were signiifcant differences on the number of spontaneous closure of the three groups.Conclusion Follow-up examination with echocardiography was important for the detection of spontaneous closure in newborns with ASP.
