Effects of aspirin on the endometrium of patients with severe intrauterine adhesions after electrical resection / 中国生化药物杂志

ABSTRACT

Objective To investigate the effect of aspirin on the endometrium of patients with severe intrauterine adhesions after electrical resection.Methods 130 patients with severe intrauterine adhesions after electrical resection from August 2013 to August 2015 in our hospital were selected and randomly divided into the observation group and the control group ( 65 cases in each group ); The control group were given progestogen sequential therapy, while the observation group were given aspirin for treatment on basis of the control group; All the two groups were treated for three menstrual cycles; Before and after treatment indexes including uterine endometrial thickness, ovulation of the uterine artery blood flow index artery pulsatility index in ultrasound (PI), resistance index (RI), endometrial blood flow parameters[vascular index (VI), flow index (FI) and vascular blood flow index (VFI)] were recorded and compared, as well as menstruation and uterine cavity shape 3 menstrual cycles after treatment;All the two groups were followed up for one year, and one year pregnancy rates in the two groups were recorded.Results After treatment, the total efficiency in the observation group was 92.3% significantly higher than 69.2% in the control group ( P <0.05 ) .After treatment, in the two groups endometrial thickness, PI, RI, VI, FI and VFI were significantly improved compared with before treatment (P<0.05), but the observation group improved more obviously (P<0.05).Within one years in the observation group the pregnancy rate was 57.1%higher than that in the control group 26.5%(P<0.05) .Conlcusions Application of aspirin can significantly improve the endometrial thickness on the basis of estrogen and progesterone sequential therapy , increase the endometrial blood flow and improve the pregnancy rate, which mechanism may be related to promoting endometrial repair and improving blood perfusion of the uterus.
