摘　　要：目的:探讨早孕子宫螺旋动脉的血流动力学变化,及与先兆流产预后的关系。方法:选择先兆流产患者98例,按预后分能维持妊娠为A组, 53例,不能维持妊娠为B组, 45例,正常宫内早孕为对照C组, 79例,经阴道彩色多普勒超声测定子宫螺旋动脉收缩期峰值流速 (PSV)、舒张期末流速 (EDV)和阻力指数 (RI)。结果:三组年龄、妊娠时间比较无明显差异(P> 0. 05);B组PSV和EDV显著性地降低,RI显著性地升高,与A组和C组比较有显著性差异(P< 0. 01)。结论:经阴道彩色多普勒超声测定早孕子宫螺旋动脉收缩期峰值流速、舒张期末流速及阻力指数对判断先兆流产预后有重要的价值。Objective To corelate blood flow changes of the uterine spiral artery in early pregnancy with the prognosis of threatened abortion using ultrasound. Methods We selected 98 patients with threatened abortion who were divided into two groups: maintainable pregnancy( group A, 53 cases ), inmaintainable pregnancy( group B,45 cases ) and 79 volunteers with normal singleton intrauterine gestation(group C ) using transvaginal sonography. The peak systolic velocity (PSV), end diastolic velocity(EDV) and resistance index(RI) of uterine spiral artery were detected and their pregnant status were followed-up respectively. Results There were no significant differences in age and duration of pregnantcy. Both PSV and EDV in group B were significantly decreased, RI in group B was significantly increased, compared with group A and C (P<0.01). Conclusion There is important value to judge the prognosis of threatened abortion to determine PSV, EDV and RI in early pregnancy by transvaginal color Doppler ultrasound.
