【摘要】：目的探讨产前超声观察胎儿主动脉弓形态对法洛四联症(TOF)的诊断价值。方法收集2012年10月—2014年10月收治的TOF胎儿109胎(TOF组),另选正常胎儿97胎(对照组),回顾性分析产前超声检查主动脉弓切面动态图像,计算最大曲率位置,对比两组间差异,并探讨最大曲率位置与孕龄的关系。结果对照组最大曲率位置为(65.63±11.01)%,TOF组为(43.28±9.10)%,差异有统计学意义(t=8.95,P0.01)。以47.18%为诊断胎儿法洛四联症的最优最大曲率位置点,此时敏感度为97.13%,特异度为73.50%。对照组最大曲率位置与孕龄呈正相关(r=0.776,P0.05);TOF组最大曲率位置与孕龄呈负相关(t=-0.537,P0.05)。结论胎儿主动脉弓形态的超声表现对丰富胎儿TOF的诊断信息和提高诊断率具有重要意义。
[Abstract]:Objective to investigate the diagnostic value of fetal aortic arch observation by prenatal ultrasound in tetralogy of Fallot. Methods from October 2012 to October 2014, 97 normal fetuses (control group) were collected. Antepartum ultrasound was used to analyze the dynamic images of aortic arch. Calculate the position of maximum curvature, compare the difference between the two groups, Results the maximum curvature position of the control group was 65.63 卤11.01 and the maximum curvature position of TOF group was 43.28 卤9.100.The difference was statistically significant. The best maximum curvature of tetralogy of Fallot was 47.18%. The sensitivity was 97.13 and the specificity was 73.50. The position of maximum curvature in the control group was positively correlated with gestational age. There was a negative correlation between the position of maximum curvature and gestational age in the control group. Conclusion the ultrasonic findings of fetal aortic arch are valuable in the diagnosis of fetal TOF. And improve the diagnostic rate is of great significance.
