Endometrial blood flow distribution measured by color Doppler energy imaging in the prediction of pregnancy outcomes during in vitro fertilization and embryos transfer cycles / 中国微创外科杂志

ABSTRACT

Objective To discuss the role of endometrial blood flow screening measured by color Doppler energy(CDE) in the prediction of outcomes in patients receiving in vitro fertilization and embryos transfer(IVF-ET).Methods A total of 182 women below the age of 38 years old undergoing IVF-ET in this center from November 2005 to December 2005 were recruited in this prospective study.The endometrial thickness,echo pattern,and blood flow status were detected by transvaginal ultrasonography on the day of hCG injection(8 hours before injection).The patients were divided into three groups: Group A,the endometrial blood flow could not be detected;Group B,only sub-endometrial blood flow could be detected;and Group C,both endometrial and sub-endometrial blood flow could be detected.All the patients were re-divided into three groups according to their outcomes of IVF-ET: Group 1,no pregnancy;Group 2,intrauterine pregnancy with live fetus and Group 3,other conditions(including biochemical pregnancy,embryonic diapause,ectopic pregnancy,and spontaneous abortion) were encountered.Results The clinical pregnancy rate with live fetus and the implantation rate were significantly higher in the Group C(62.2% and 65.6%) than in the Group A(0 and 0) and the Group B(17.1% and 20.7%),respectively(P
