Study The Relevance Between The Blood Stream Of The Spiral Artery Under The Endometrium And Pregnancy Using Transvaginal Color Doppler Sonography

Objective:The present paper is for the purpose of discussing the womanof child-bearing age in the course of the menstrual cycle endometrial proliferative changes in the uterine artery blood flow parameters particularly uterine artery resistance index spiral pregnancy and the relationship.Method:Through to 76 examples sterility patient after the vaginacolored B ultra monitor,observes it with the clinical coordination tobecome pregnant the situation,then according to becomes pregnant it,has not become pregnant the woman to divide according to the group,and from clinical stochastically extracts 30 examples to give birththe normal embryo's child-bearing age time woman to take thecomparison, counts its each parameter value.Results:In normal pregnancy group and the group of women with follicular development of endometrial thickening were positively correlated;spiral ovulation period uterine artery blood flow was rich continuous wave of high-amplitude, low resistance index.Pregnant women's group did not follicular development and the lack of endometrial thickening cyclical,ovulation period spiral uterine artery blood flow was slim non-continuous wave of low-amplitude,the resistance index increased significantly.The results were significantly different,P＜0.01.Conclusion:Follicular development and cyclical changes and uterine endometrium spiral artery resistance index synergies between the three,and the closely related with pregnancy.
