History of Uterine Artery Occlusion and Subsequent Pregnancy

OBJECTIVE. During mature placenta formation, select fetal trophoblasts invade maternal decidual arterioles and junctional zone arteries and change them into low-resistance uteroplacental arteries. Consequently, physicians performing vascular procedures that occlude the uterine arteries should understand their effects on miscarriage rates, the various toxemias of pregnancy, gross and microscopic placental anatomy, and invasive placentation. Thus, the objective of this article is to review the effects of vascular occlusion on pregnancy. CONCLUSION. In the long run, placental abnormalities may be the canary in the mine shaft to globally judge the effect of uterine artery embolization on pregnancy.
