目的 探讨二维超声诊断胎儿主动脉缩窄(COA)的直接和间接指标的应用价值。方法 回顾性分析经胎儿超声心动图检查诊断、并经出生后或尸体检查证实为COA的中孕期胎儿18胎。以主动脉峡部Z分数(Z-AoI)<-2、主动脉峡部内径(AoId)≤2.0 mm、主肺动脉内径/升主动脉内径(MPAd/AAOd)≥1.6、二尖瓣环横径/三尖瓣环横径(MVd/TVd)<0.6为诊断标准,分别分析其诊断符合率,同时测量主动脉瓣环内径(AOd),计算中孕期COA胎儿AOd的参考范围。结果 在18胎COA胎儿中,Z-AoI、AoId、MPAd/AAOd、MVd/TVd的诊断符合率分别为94.44%(17/18)、61.11%(11/18)、66.67%(12/18)、44.44%(8/18),差异有统计学意义(P<0.05)。COA胎儿AOd的参考范围为2.60~2.98 mm。结论 Z-AoI诊断COA的符合率最高;中孕期COA胎儿AOd为2.60~2.98 mm。 |

Objective To investigate and verify the diagnostic accordance rate of the currently commonly used direct and indirect indicators of two-dimensional ultrasound on the fetal coarctation of the aorta (COA). Methods The echocardiography data of 18 cases of fetal aorta coarction in the second trimester of pregnancy, confirmed by after birth or autopsy, were analysis retrospectively. Aortic isthmus Z-score (Z-AoI) <-2, aortic isthmus diameter (AoId) ≤2.0 mm, the main pulmonary artery diameter/ascending aorta diameter (MPAd/AAOd) ≥1.6, mitral valve annulus diameter/tricuspid valve annulus transverse diameter (MVd/TVd) <0.6 as the individual diagnosis indicator of COA, the diagnosis accordance rate was calculated. The aortic valve annulus diameter (AOd) was measured, and the reference range of AOd on fetal coarctation of aorta in the second trimester of pregnancy was calculated. Results Among 18 COA fetuses, the diagnosis accordance rate of Z-AoI, AoId, MPAd/AAOd, MVd/TVd as individual diagnosis indicator was 94.44% (17/18), 61.11% (11/18), 66.67% (12/18) and 44.44% (8/18) respectively. The difference was statistically significant (P<0.05). The reference range of AOd in fetal COA was 2.60—2.98 mm. Conclusion The diagnosis accordance rate of Z-AoI is highest in all the 4 common two-dimensional ultrasound indicators. AOd of COA fetus in the second trimester of pregnancy is 2.60—2.98 mm. |
