摘　　要：目的探讨二维联合时间-空间关联成像(STIC)在胎儿主动脉弓缩窄(COA)中的诊断价值。资料与方法回顾性分析29例超声诊断为COA患者的二维及STIC图像;纳入同期29例正常胎儿作为对照组。测量两组胎儿左心室横径(LVD)、右心室横径(RVD)、主动脉瓣环处内径(AO)、肺动脉瓣环处内径(PA)、主动脉弓降部内径(DA)、降主动脉穿横膈处内径(DAO)。计算并比较两组RVD/LVD、PA/AO、DA/DAO及DA/AO比值的差异。结果COA组RVD/LVD及PA/AO分别为1.68±0.11、1.63±0.12,均显著高于对照组的1.33±0.06、1.30±0.07,差异有统计学意义(P<0.01);COA组DA/DAO、DA/AO分别为0.50±0.11、0.50±0.10,均显著低于对照组的0.90±0.07、0.90±0.07,差异有统计学意义(P<0.01)。以DA/DAO≤0.6为标准诊断COA的敏感度为93.1%;以DA/DAO≤0.5为标准诊断COA的敏感度为94.1%。与CT血管造影结果比较,二维联合STIC诊断胎儿COA的敏感度为95.8%。结论二维联合STIC可用于辅助诊断胎儿主动脉弓缩窄,具有重要的临床价值。Purpose To explore the diagnostic value of two-dimensional ultrasound combined with spatiotemporal image correlation(STIC)in fetal coarctation of aorta(COA).Materials and Methods Two-dimensional and STIC images of 29 patients diagnosed as COA by ultrasound were retrospectively analyzed;29 normal fetuses in the same period were included as the control group.Fetal left ventricular transverse diameter(LVD),right ventricular transverse diameter(RVD),inner diameter of aortic annulus(AO),inner diameter of pulmonary annulus(PA),inner diameter of descending aortic arch(DA)and descending aorta inside diameter(DAO)were measured.The RVD/LVD,PA/AO,DA/DAO and DA/AO ratios between the two groups were calculated,and the differences between the two groups were compared.Results RVD/LVD and PA/AO in the COA group were 1.68±0.11 and 1.63±0.12,respectively,which were significantly higher than the control group of 1.33±0.06 and 1.30±0.07,the difference was statistically significant(P<0.01);DA/DAO and DA/AO of the COA group were 0.50±0.11 and 0.50±0.10,respectively,which were significantly lower than those of the control group 0.90±0.07 and 0.90±0.07,the difference was statistically significant(P<0.01).With DA/DAO≤0.6 as the standard,the sensitivity for the diagnosis of COA was 93.1%;with DA/DAO≤0.5 as the standard,the sensitivity for the diagnosis of COA was 94.1%.Compared with the CTA results,the sensitivity of two-dimensional combined STIC diagnosis of fetal COA was 95.8%.Conclusion Two-dimensional combined with STIC can be used to assist in the diagnosis of fetal COA,and it has important clinical value.
