目的分析胎儿期彩超在卵圆孔产后闭合的预测中的价值。方法 150例做心脏筛查并在产后随访记录的患儿,根据产后房间隔闭合时间分为三组,A组60例患儿<3个月闭合,B组42例患儿于3~6个月闭合,C组48例患儿>6个月闭合,对比三组卵圆孔直径及各项指标。结果 C组患儿卵圆孔直径明显大于A、B两组,卵圆孔流速明显低于A、B两组,肺动脉内径、肺动脉流速及动脉导管流速均高于A、B两组,差异具有统计学意义(P<0.05);A、B两组患儿各指标比较,差异无统计学意义(P>0.05)。结论彩超对诊断胎儿期卵圆孔具有较高应用价值,可初步预测卵圆孔闭合情况。
Objective To analyze the value of fetal color Doppler ultrasound in the prediction of foramen ovale closure. Methods A total of 150 children undergoing cardiac screening and follow-up postpartum were divided into three groups according to the time of atrial septal closure. A group of 60 children <3 months closed, B group 42 children in 3 to 6 Month closure, 48 children in group C were closed for> 6 months, and the diameters and indexes of foramen ovale in the three groups were compared. Results The diameter of foramen ovale was significantly larger in group C than in groups A and B. The foramen ovale velocity was significantly lower in group C than in groups A and B. The diameters of pulmonary artery, pulmonary artery and catheter were higher than those in groups A and B Statistical significance (P <0.05); There was no significant difference between the two groups (P> 0.05). Conclusion Color Doppler ultrasound diagnosis of fetal foramen ovale has high value, preliminary prediction of foramen ovale closure.
