摘要
目的 :超声随访研究小儿房间隔缺损 ( ASD)的自然愈合。方法 :超声诊断和随访观察 91例ASD患儿的 ASD直径、部位、右室大小及年龄与自然愈合的关系。结果 :91例 ASD自然愈合 2 0例 ,自愈率 2 1.98%。 ASD直径 0 .5～ 0 .7cm自愈率 69.2 3% ,0 .8～ 10 cm自愈率 2 7.2 7% ,>1.0cm自愈率 2 .2 7%。中央型 ASD自愈率 2 3.2 6% ,腔静脉窦型 ASD未自然愈合。ASD自然愈合年龄 7个月～ 6岁 ,中位数 1.6岁。右室增大的 ASD自愈率为 9.4 6% ,右室正常的 ASD自愈率为63.64%。结论 :ASD直径≤ 1.0 cm、中央型 ASD、右室正常及年龄 <6岁尤其是 2岁以内的 ASD自然愈合的可能性较大。 ASD直径 >1.0 cm、腔静脉窦型 ASD、右室增大及 6岁以上的 ASD自然愈合机会很小。
Objective:To observe spontaneous closure of atrial septal defects(ASD) in children by echocardiography. Methods:The diameters of ASD,the sites of ASD and the diameters of right ventri cular were observed and follow up in 91 ASD patients by echocardiography.Results:The overall rate of spontaneous closure of ASD was 21.98%.Spontaneous closure occurred in 69.23%(9 of 13) of the patients with ASD of 0.5 to 0.7 cm in dimeter,in 27.27%(9 of 33) of 0.8～1.0 cm,in 2.27%(1 of 44) of >1.0 cm.Spontaneous closure occurred in 22.35%(19 of 85) of the patients with ASD and did not occurred in 5 patients with sinus venosus defects.The age of spontaneous closure was 7 months to 6 years and most occured in 2 years of age.The spontaneous closure occurred in 9.46%(7 of 85) of the patients associated with right ventricular dilation and 63.64%(7 of 11) with right ventricular normal.Conclusion:These results suggest that the patients with ASD diameter≤1.0 cm,secundum ASD,right ventricular normal and age <6 years have higher possibitity of spontaneous closure.The patients with ASD diameter>1.0 cm,sinus venosus ASD,right ventriacular dilation and age> 6 years may have little chance of closing spontaneously.
