14 By ∼gd 10.5, the thin-walled, large diameter, coiling spiral arteries in the decidua have formed, and they supply blood flow to trophoblast tubes, called maternal arterial canals, 10 arising near the central region of the junctional zone 10 (Figure 4). One year later, they conducted another study comparing the Doppler flow of the spiral arteries and cervical branch of the uterine artery 1–2 and 4–6 months after LNG‐IUS insertion in 36 women who were using it for contraception. 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]. Vascular effect of levonorgestrel intrauterine system on heavy menstrual bleeding: is it associated with hemodynamic changes in uterine, radial, and spiral arteries? Published June 24, 2020. Abstract.

A perhaps understudied aspect of the spiral arteries in the basal decidua is their appearance when they underlie lesions of placental infarction, retroplacental hematoma, subchorionic thrombohematoma, and infarction hematoma. Perinatal asphyxia during labor is the most serious potential complication.

It is a risk if intrauterine growth restriction is caused by placental insufficiency (with marginally adequate placental perfusion) because each uterine contraction slows or stops maternal placental perfusion by compressing the spiral arteries. Se hela listan på academic.oup.com For the diagnostic purpose, biochemical serum markers, ultrasound and Doppler study of uterine and spiral arteries, placental volume and vascularization, first trimester growth pattern are object of assessment today. Modern evaluations propose combined algorithms using these strategies, all with the goal of a better prediction of risk pregnancies. When complete, the UPCS includes spiral arteries and decidua on the maternal side, placental villi on the fetal side and, in between the two, the intervillous space where oxygen and nutrient exchange occurs.

Similar sections were stained for trophoblastic and vascular antigens. Spiral arteries in endometrium from ectopic (tubal) and intrauterine pregnancies were compared also. Uterine spiral arteries are the conduits for delivering maternal nutrients to the fetus.

In normal pregnancies, the resistance index of spiral artery flow velocity waveforms decreased significantly with advancing gestation (r = -0.256, p < 0.001). In abnormal pregnancies complicated by pregnancy-induced hypertension and/or intrauterine growth 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 Of these, six (75%) and three (50%), respectively, proceeded to delivery (not significantly different). We found no differences in uterine or spiral artery PI or PSV when comparing women that conceived with IVF‐ET with women who did not. One woman with tubal infertility had absent spiral arteries on the day of ET, and she did not conceive. arteries exhibiting varying degrees of luminal occlusion in placentae from cases of intrauterine growth retardation.

Vascular effect of levonorgestrel intrauterine system on heavy menstrual bleeding: is it associated with hemodynamic changes in uterine, radial, and spiral arteries? Published June 24, 2020 Abstract Enlarged hyalinized spiral arteries and fibrinoid matrix are suggestive Decidual reaction, gestational hyperplasia (glandular secretion, stromal edema) and Arias-Stella reaction are suggestive of pregnancy (not necessarily intrauterine) but are nonspecific (also occur with hormones) 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. Objective. Evaluate if different bleeding patterns associated with the use of the levonorgestrel intrauterine system (LNG-IUS) are associated with different uterine and endometrial vascularization patterns, as evidenced by ultrasound power Doppler analysis.
