The aim of this study was to use three-dimensional (3D) ultrasound to detect ultrasound parameters related to the uterine artery and endometrium, evaluate endometrial receptivity, and investigate the predictive value of each parameter for ectopic pregnancy (EP) after in vitro fertilization-embryo transfer (IVF-ET).
Fifty-seven cases of pregnancy following IVF-ET in our institution were collected and split into EP and intrauterine pregnancy (IP) groups based on the location of pregnancy, with 27 cases in EP and 30 cases in IP. Endometrial thickness, type, volume, endometrial blood flow parameters, and uterine artery blood flow parameters were all measured one day before transplantation in both groups, and the differences between the two groups were examined.
There were differences in endometrial blood flow typing between the two groups, with type III endometrium accounting for the highest proportion in both; the uterine spiral artery pulsatility index PI was significantly higher in the EP group than in the IP group; there were no statistical differences in uterine volume, uterine artery resistance index mRI, or uterine artery resistance index S/D between the two groups; there were no statistical differences in uterine volume, or uterine artery.
Intracavitary 3D ultrasound can assess endometrial tolerance and may predict pregnancy outcome after IVF-ET.
本研究旨在使用三维（3D）超声检测与子宫动脉和子宫内膜相关的超声参数，评估子宫内膜容受性，并探讨各参数对体外受精-胚胎移植（IVF-ET）后异位妊娠（EP）的预测价值。
收集了我院 57 例 IVF-ET 后妊娠病例，根据妊娠部位分为 EP 组和宫内妊娠（IP）组，其中 EP 组 27 例，IP 组 30 例。两组均于移植前一天测量子宫内膜厚度、类型、体积、子宫内膜血流参数和子宫动脉血流参数，并比较两组间的差异。
两组子宫内膜血流类型存在差异，均以 III 型子宫内膜为主；EP 组子宫螺旋动脉搏动指数 PI 明显高于 IP 组；两组子宫体积、子宫动脉阻力指数 mRI、子宫动脉阻力指数 S/D 无统计学差异；子宫体积、子宫动脉无统计学差异。
腔内 3D 超声可评估子宫内膜容受性，可能预测 IVF-ET 后妊娠结局。
