Solfrini S, Rossi M, Tarsitano F, Giampalma E, Antonazzo P. What to learn from a case of short-term pregnancy after uterine artery embolization for acquired uterine arteriovenous malformation. J Case Rep Images Obstet Gynecol 2022;8: 100105Z08SS2022.ABSTRACT
Introduction: Acquired uterine arteriovenous malformations are rare causes of bleeding occurring after uterine curettage, gestational disease, abortion, or delivery. Uterine artery embolization is a safe and effective procedure to treat bleeding, although outcomes on fertility and subsequent pregnancy are yet to be defined.
Case Report: A 34-year-old nulliparous woman underwent medical treatment with misoprostol for first trimester miscarriage. After two weeks a transvaginal ultrasound found a round myometrial lesion with hypoechoic spaces, abundant vascularization suggestive of an acquired uterine arteriovenous malformation. A conservative management was adopted with ultrasound follow-up. Twenty days later a severe bleeding occurred and the patient was treated with bilateral uterine artery embolization. After three months the patient got pregnant and gave birth at term to a healthy and normal weight baby. Third stage of labor was complicated by placental retention requiring manual removal and postpartum hemorrhage managed with uterine hemostatic balloon positioning and blood transfusion.
Conclusion: In this case uterine artery embolization was followed by a very short-term pregnancy with vaginal birth and excellent neonatal outcome. Uterine ischemic changes could predispose to placental adhesion anomalies and contraction dysfunctions. An accurate ultrasound screening for placenta accreta spectrum disorders and an active management of third stage could be suggested.
