Purpose To compare endometrial and subendometrial morphological changes
and vascularity as measured by 3D Power Doppler sonography, based on a
specific scoring system between women subjected or not to oxytocine
receptor antagonist (OTRa) during IVF cycles.
Methods Twenty-six women were divided into groups according to OTRa
(Atosiban tractocide) administration. The first group (control n = 13
women) was examined with 3D Power Doppler 3 days after embryo transfer.
The second group (n = 13 women) was administered 7.5 mg intravenous
tractocide 2 days after embryo transfer and a 3D Power Doppler was
performed after a day.
Results The control group presented the following ultrasonographic
characteristics: (a) echogenic endometrium in all cases, (b) endometrial
thickness >7 mm in all cases (84.6%), (c) endometrial volume >2.31
cm(3) in 5 cases (38.5%), (d) abnormal sub-endometrial halo in 3 cases
(23.1%), (e) endometrial blood flow in 6 cases (46.2%) and (f) complex
vessel’s architecture in 2 cases (15.4%). In women who underwent OTRa
administration were observed: (a) echogenic endometrium in 1 case
(7.7%), triple line endometrium in 12 cases (92.3%), (b) endometrial
thickness >7 mm in all cases, (c) endometrial volume >2.31 cm(3) in 11
cases (84.6%), (d) abnormal sub-endometrial halo in 3 cases (23.1%),
(e) endometrial blood flow in 11 cases (84.6%) and (f) complex vessel’s
architecture in 6 cases (46.2%).
Conclusions Women who have taken OTRa presented an endometrium with
characteristics more predictive of implantation.
