Intrauterine spiral arteries

Uterine arterial vasculature, showing spiral arteries at right. In the uterine spiral arteries, the trophoblasts interdigitate between the endothelial cells (ECs), replacing the endothelial lining and most of the musculoelastic tissue in the vessel walls. This creates a high-flow, low-resistance circulation that increases maternal blood flow to the placental villi at the maternal-fetal interface. Measurements of uterine and spiral artery impedance were taken on days 11–12, 16–17 and 21–23 of the spontaneous cycle and on days 1, 5 and 10 during gonadotropin stimulation. In addition, measurements were taken on the days of oocyte pick‐up and embryo transfer. Extravillous trophoblast remodeling of the uterine spiral arteries is essential for promoting blood flow to the placenta and fetal development, but little is known about the regulation of this process. Spiral arteries are blood vessels of the uterus arising from the uterine artery which extend from within the myometrium into the decidua in pregnancy and deliver maternal blood to the placental Introduction Uterine spiral arteries (SpAs) in decasualized endometrium and inner myometrium undergo profound morphological changes in successful human pregnancy.

The uterine artery is a branch of the anterior division of the internal iliac artery, arising below the obturator artery. It runs inferiorly and medially along the lateral wall of the lesser pelvis, coursing into the inferior part of the broad ligament of uterus called the cardinal ligament.

They demonstrated no change in RI of the cervical branch but a significant increase in RI of the spiral artery. Abnormally high impedance to blood flow in the uterine arteries has been associated with failure of physiological transformation of the spiral arteries [1,14,37,69,75,95,130,152].

Results: We found fewer spiral arteries with complete remodeling in women with preeclampsia than in the control group (21 vs. 68%; P = 0.008). Further, women with preeclampsia showed less presence of CD3 + cells in both the decidua and the myometrium.

Methods A prospective study was designed to compare the placental circulation of 30 uncomplicated pregnancies of 8–12 completed gestational weeks terminated by legal abortion and 30 pregnancies complicated with first This study concludes that high pulsatility index in uterine arteries is associated with intrauterine growth restriction. This occurs due to inadequate VEGF secretion from maternal decidua resulting inhigh velocity, low volume diastolic flow in the uterine artery supplying the spiral arterioles, that subsequently leads to the damage of fetal tertiary stem villi floating in the intervillous space. Perinatal asphyxia during labor is the most serious potential complication.
