Key result
Uterine artery embolization is linked to placental abnormalities in two subsequent pregnancies.
Why the study?
Complications during pregnancy after uterine artery embolization for uterine arteriovenous malformation have not been clearly described.
Does uterine artery embolization for uterine arteriovenous malformation increase the risk of placental abnormalities in subsequent pregnancies?
Case Report (n=2)
No
Does uterine artery embolization for uterine arteriovenous malformation increase the risk of placental abnormalities in subsequent pregnancies?
While successful pregnancy is possible after uterine artery embolization for uterine AVM, clinicians must be vigilant for placental abnormalities such as placenta accreta and abruption.
Placental abnormalities may complicate post-UAE pregnancies; case report leaves open true incidence and causality.
Uterine arteriovenous malformation (AVM) is generally associated with uterine trauma such as dilatation and curettage, therapeutic abortion, uterine surgery and uterine malignant tumors(1)). Uterine artery embolization (UAE) is performed on patients with uterine AVM who have desire for future pregnancy(2)). Some successful pregnancies were reported after UAE for uterine AVM(5,6)), however complication during pregnancy has not been described clearly. We herein for the first time report two cases of successful pregnancy and spontaneous delivery after UAE for uterine AVM who had placenta accreta and placental abruption respectively. Although successful pregnancy is possible after UAE for AVM, placenta abnormalities have to be considered during pregnancy and after delivery.

Soeda et al. (2014) conducted a case report in Uterine arteriovenous malformation (n=2). Uterine artery embolization was evaluated on Placental abnormalities in subsequent pregnancy. Uterine artery embolization for uterine arteriovenous malformation was followed by successful pregnancies but complicated by placental abnormalities, specifically placenta accreta and placental abruption, in two cases.
