目的 建立中孕中期胎儿心轴角度的相应统计参数,并评价中孕中期测定胎儿心轴角度在产前诊断中的应用价值.方法 选择2008年9月至2010年10月复旦大学附属妇产科医院常规产科检查的孕妇6744例,均为单胎.于孕18～23+6周行中孕中期胎儿畸形筛选超声的同时,进行胎儿心脏超声检查,于四腔心观测量胎儿心轴角度.结果 6744例胎儿心轴角度测量值为(37.03±6.10)°,范围9.80°～102.41°.按超过普通人群中胎儿的心轴角度的95％的参考值范围(26.63°～49.40°)为异常心轴.正常组胎儿的心轴平均角度为(36.96±5.91)°,心脏结构异常组的心轴平均角度为(43.12±15.67)°,胸腹腔异常组的心轴平均角度为(51.74±15.97)°,与正常组相比差异有统计学意义(P＜0.01).结论 本地区胎儿心轴角度参数的建立将有助于发现相当一部分的心脏结构畸形或胸腔腹壁病变,可作为常规心脏畸形筛选的补充及某些畸形的诊断标准.
目的 建立中孕中期胎兒心軸角度的相應統計參數,併評價中孕中期測定胎兒心軸角度在產前診斷中的應用價值.方法 選擇2008年9月至2010年10月複旦大學附屬婦產科醫院常規產科檢查的孕婦6744例,均為單胎.于孕18～23+6週行中孕中期胎兒畸形篩選超聲的同時,進行胎兒心髒超聲檢查,于四腔心觀測量胎兒心軸角度.結果 6744例胎兒心軸角度測量值為(37.03±6.10)°,範圍9.80°～102.41°.按超過普通人群中胎兒的心軸角度的95％的參攷值範圍(26.63°～49.40°)為異常心軸.正常組胎兒的心軸平均角度為(36.96±5.91)°,心髒結構異常組的心軸平均角度為(43.12±15.67)°,胸腹腔異常組的心軸平均角度為(51.74±15.97)°,與正常組相比差異有統計學意義(P＜0.01).結論 本地區胎兒心軸角度參數的建立將有助于髮現相噹一部分的心髒結構畸形或胸腔腹壁病變,可作為常規心髒畸形篩選的補充及某些畸形的診斷標準.

Objective To establish the reference ranges for fetal cardiac axis in the mid-second trimester and to evaluate the use of fetal cardiac axis in prenatal diagnosis.Methods 6744 unselected singleton pregnancies were enrolled from September 2008 to October 2010.Routine screening scan of second trimester and fetal echocardiography were performed at 18- 23+6 weeks gestation.Fetal cardiac axis was measured on the four-chamber view of the heart.Results The 6744 fetuses had a mean cardiac axis of (37.03 ± 6.10)°,ranging from 9.80° to 102.41°. Using above or below 95％ range of population (26.63° -49.40°) as a cut-off,there were significant difference of cardiac axis between normal group [(36.96 ± 5.91)°,P ＜0.01] and the group with heart defects [(43.12 ± 15.67)°,P ＜0.01],the group with intrathoricic anomalies or abdominal wall defect [(51.74 ± 15.97)°].Conclusions The reference ranges of fetal cardiac axis for local population in mid-second trimester may helpful for detecting congenital defects.Presence of an abnormal cardiac axis in the fetuses is associated with a substantial risk of congenital heart disease and/or other extra cardiac defects.
