    Abstract
  •   Objective  To evaluate the clinical effect of transvaginal ultrasound in the diagnosis of abortion during early pregnancy.  Methods  The research objects were 140 cases of threatened abortion and 140 cases of healthy pregnant women. The pregnancy outcomes were tracked by using transvaginal ultrasound. The luteal characters and ultrasonic echo characteristics of pregnant women with different pregnancy outcomes were compared, and the differences of ultrasound indexes of corpus luteum and uterine spiral artery blood flow were counted.  Results  The shape of corpus luteum in healthy pregnant women was circular (100.00%); in threatened abortion group, a small number of corpus luteum showed rod shape (21.21%) and dot shape (4.04%). In the abortion of early pregnancy group, the proportion of the subjects with rod shape (34.15%) and dot shape (26.83%) corpus luteum was the highest. The detection rate of heterogeneous hypoechoic corpus luteum in healthy pregnant women was the lowest (12.86%), and in the middle in the group with successful fetus protection group among those with threatened abortion was (38.38%), and the highest in the abortion of early pregnancy group (58.54%). The PSV of luteal blood flow of healthy pregnant women was significantly higher than that of the other two groups, whereas RI was significantly lower than that of the other two groups (all P < 0.05). The PSV(peak systolic velocity) of luteal blood flow in the fetus protection group among those with threatened abortion group was significantly higher than that in the abortion of early pregnancy group, whereas the luteal blood flow RI was significantly lower than that in the abortion of early pregnancy group (all P < 0.05). The pulsatility index (PI), resistive index(RI) systolic/diastolic (S/D) ratio in healthy pregnant women were significantly lower than those in the other two groups (all P < 0.05), and the PI and RI of uterine spiral artery blood flow in the successful fetus protection group among those with threatened abortion were significantly lower than those in the abortion of early pregnancy group (all P < 0.05).  Conclusion  Transvaginal ultrasound detection of corpus luteum and uterine spiral artery blood flow has a high value in the diagnosis and prognosis evaluation of abortion of early pregnancy.
