Background. To determine whether adequate trophoblastic migration and maternal
placental perfusion occurs in cases of early pregnancy loss, we compared vessels in …

Abstract Spontaneous pregnancy loss affects 15–18% of couples, and a number of potential
causes are being discussed. The purpose of the present study was to assess if angiogenic …

In many cases of early spontaneous abortion (ESA), no reasonable etiology can be
documented. However, some of these cases show abnormal decidual vessels that could be …

Objective: To determine whether maternal placental perfusion occurs in the first trimester,
this study compared veins in endometrium with those in decidua. We hypothesize that veins …

During the first trimester in normal human pregnancy, endovascular trophoblast migrate
along the decidual spiral arteries and invade their walls to produce physiological change …

Transvaginal color Doppler was used to investigate blood flow in the fetomaternal circulation
of 60 women with threatened abortion and 90 women with normal intrauterine pregnancy …

Objective: To assess uteroplacental circulation in patients with first-trimester threatened
abortion with a living embryo. Design: Prospective, cross-sectional study. Setting: Tertiary …

STUDY QUESTION Do extravillous trophoblasts (EVTs) invade non-arterial decidual vessels
in healthy and pathological pregnancies? SUMMARY ANSWER Our results reveal that …

The chorionic villous vascularization of 40 patients with first trimester spontaneous abortion
was compared with that of 10 patients undergoing legal abortion (control group). The …

Pregnancy-induced structural changes in spiral arteries seem to be a prerequisite for
successful fetal outcome in humans. It is unknown whether these changes also occur in …
