【摘要】：目的:利用彩色多普勒超声心动图对小儿继发孔型房间隔缺损与卵圆孔未闭的自然愈合情况进行随访,比较两者在自然愈合时间和愈合率上的差别。方法:依据房间隔缺损和卵圆孔未闭的判断标准对存在心房间分流的220例新生儿进行超声心动图检查,并将其分成三组:房间隔缺损直径≤3mm组(A组)48例、房间隔缺损直径3mm组(B组)30例,卵圆孔未闭组(C组)142例,分别对其在出生后6个月、出生后1年、出生后2年进行定期超声随访,记录各组的自然愈合例数并计算出自然愈合率。结果:A组出生后6个月、出生后1年和出生后2年的自然愈合率分别为16.7%(8/48)、52.1%(25/48)、93.8%(45/48);B组分别为:6.7%(2/30)、13.3%(4/30)、23.3%(7/30);C组分别为:80.3%(114/142)、95.1%(135/142)、98.6%(140/142)。对同一时间点上的三组的自然愈合率两两进行卡方检验,出生后6个月时,C组的自然愈合率高于A组和B组(P0.05),A组和B组比较无统计学意义(P0.05),出生后1年时,C组高于A组和B组(P0.05),A组高于B组(P0.05),出生后2年时,C组和A组均高于B组(P0.05),A组和C组比较无统计学意义(P0.05)。结论:继发孔型房间隔缺损在出生后6个月内不容易愈合,当继发型房间隔缺损的直径≤3mm时,其出生后6个月至2年时自然愈合的概率很高,而当缺损的直径3mm则不容易自然愈合,卵圆孔未闭大多在6个月至1岁时自然愈合,相对房间隔缺损要早一些,然而出生后2年时它与3mm的继发孔型房间隔缺损的自然愈合率差别不大。
[Abstract]:Objective: to follow up the natural healing of secondary atrial septal defect (ASD) and patent foramen ovale in children by color Doppler echocardiography. Methods: according to the criteria of atrial septal defect and patent foramen ovale, 220 neonates with cardiac shunt were examined by echocardiography. They were divided into three groups: group A (n = 48), group A (n = 48), group B (n = 30) with diameter of atrial septal defect (n = 3), group C (n = 142) with patent foramen ovale. Two years after birth, regular ultrasound follow-up was performed to record the number of cases of natural healing in each group and to calculate the rate of natural healing. The natural healing rates in the first year after birth and in the second year after birth were 16.780 / 48, 52.1Q / 25 / 93.885 and 454548m / b, respectively. The natural healing rate in group B was 6.7R / 2.3030 / 13.3C = 80.33.30 / 30C = 80.3114142/ 95.998 / 698.698.698.698.698.698.698.698.698.698 / 142Q / 1421.The natural healing rate of the three groups at the same time was examined by caloric test. At 6 months after birth, the rate of spontaneous healing in group C was higher than that in group A and group B (P 0.05). There was no significant difference between group A and group B, but at one year after birth, the rate of spontaneous healing in group C was higher than that in group A and group B (P 0.05), and in group C and group A were higher than that in group B at 2 years after birth. There was no significant difference between group A and group C. conclusion: secondary atrial septal defect is not easy to heal within 6 months after birth. When the diameter of secondary atrial septal defect was 鈮，
