摘要
为探讨超声心动图诊断胎儿卵圆孔血流受限或提前闭合(FO-R/C)的价值,本文分析了31例FO-R/C胎儿(观察组)和30例正常胎儿(对照组)超声心动图资料,以病理或出生后超声心动图诊断结果为准,分析超声心动图诊断FO-R/C的效能。结果显示,观察组胎儿卵圆孔最大流度、右室与左室内径比值(RV/LV)、右房与左房内径比值(RA/LA)、主肺动脉与主动脉内径比值(MPA/AO)、肺动瓣上/主动脉瓣上血流速度比值(VMPA/VAO)、心胸比、静脉导管阻力指数均大于对照组(P<0.05),卵圆孔直径、卵圆孔与主动脉瓣环比、卵圆孔与右房横径比小于对照组(P<0.05)。RA/LA、VMPA/VAO、卵圆孔最大流度、静脉导管阻力指数诊断FO-R/C具有较高效能。由上述结果可知超声心动图可用于辅助诊断FO-R/C。
To investigate the value of echocardiography in the diagnosis of fetal foramen ovale restriction or closure(FO-R/C),we analyzed 31 cases of FO-R/C(observation group)and 30 cases of normal fetal echocardiography(control group).The efficacy of echocardiography in diagnosing FO-R/C was analyzed based on pathological or postnatal echocardiography diagnosis results.The results showed that the maximal fluidity,the ratio of right ventricle diameter to the left(RV/LV)and the ratio of right atrium diameter to the left(RA/LA)were all higher than those in the control group(P<0.05),as well as the ratio of main pulmonary artery diameter to the aorta(MPA/AO),the ratio of pulmonic supravalvular blood flow velocity to the aortic supravalvular(VMPA/VAO),cardiothoracic ratio and the resistance index of venous catheter.While the diameter of FO and the ratio of FO to aortic valve ring were smaller than those in the control group(P<0.05),as well as the ratio of FO to right atrial transverse diameter.In conclusion,it can be confirmed that RA/LA,VMPA/VAO,maximum fluidity of FO and resistance index of venous catheter are effective in diagnosing FO-R/C.It is concluded that echocardiography can be used to assist the diagnosis of FO-R/C.
