A comparison of endometrial and subendometrial vascularity assessed by three-dimensional ultrasonography and power Doppler angiography between healthy fertile women and women with unexplained primary recurrent miscarriage.

摘要

We compared the characteristics of endometrial-subendometrial vascularity 7 days after ovulation of a natural cycle by transvaginal three-dimensional ultrasonography and power Doppler angiography between 88 patients with unexplained recurrent miscarriage and 46 healthy fertile women. Endometrial vascularization index, flow index, and vascularization flow index, as well as subendometrial vascularization index and vascularization flow index, were reduced significantly in the group with unexplained recurrent miscarriage.
