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。

Abstract: 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.
