摘　　要：目的通过彩色多普勒超声分析探讨胎儿卵圆孔通道血流受限(FOCR)的诊断价值。方法应用彩色多普勒超声对符合FOCR诊断的16例胎儿均检测卵圆孔(FO)、左右心房、左右心室、主动脉及肺动脉的内径,观察彩色多普勒血流充盈情况,与正常对照组比较,做差异性测定,检测主动脉弓末段逆向血流频谱形态、方向及左心室射血时间(LVET)、逆向血流持续时间(ARCH-RET)、记录各项参数以备分析。结果16例胎儿均可见明显的左心系统充盈不足,左心室及主动脉内径减小,与正常组对照差异有统计学意义(P<0.05),主动脉弓末段均出现不同程度的逆向血流,ARCH-RET为48~92 mms,ARCH-RET/LVET比值为0.26~0.50。结论观察组胎儿均出现左心系统不同程度的血流充盈不良及主动脉弓末段在收缩末期出现逆向血流现象,后者可作为诊断FOCR的必要条件。Objective To explore the diagnostic criteria of fetal foramen ovale channel flow restriction(FOCR)by hemodynamic analysis.Methods Color Doppler ultrasound was used to detect the inner diameter of foramen ovale(FO),left and right chambers,left and right ventricles,aorta and pulmonary artery in 16 fetuses with FOCR diagnosis,and to observe the color Doppler blood flow filling.The spectral morphology and direction of the reverse blood flow at the end of the aortic ARCH,the time of left ventricular ejection(LVET)and the duration of reverse blood flow(ARCH-RET)were detected,and all parameters were recorded for analysis.Results All the 16 fetuses showed obvious insufficiency of left heart system,and the inner diameter of left ventricle and aorta decreased,which was significantly different from that of the normal group(P<0.05).Reverse blood flow was observed in the distal aortic ARCH of different degrees.ARCH-RET was 48~92 mms.ARCH-RET/LVET ratio was 0.26~0.50.Conclusion All the fetuses in the observation group had abnormal blood flow in the left heart system and reverse blood flow in the terminal aortic arch at the end of contraction.The latter can be used as a necessary condition to diagnose FOCR.
