Embolization of a Uterine Arteriovenous Malformation Followed by a Twin Pregnancy

Abstract

In Brief BACKGROUND Uterine arteriovenous malformation is a lesion that can cause recurrent pregnancy loss. Very few successful pregnancies have been reported after selective embolization of an arteriovenous malformation. CASE A 42-year-old gravida 6 para 0 with a history of four first-trimester spontaneous abortions was found to have a uterine arteriovenous malformation by hysterosalpingogram, which was confirmed by magnetic resonance angiography. She underwent selective transcatheter embolization of the arteriovenous malformation. A twin gestation was later conceived via in vitro fertilization. The twins were delivered by cesarean at term. CONCLUSION Uterine arteriovenous malformation can be successfully treated with selective embolization, with good obstetric outcome. In a patient with prior pregnancy losses, embolization of auterine arteriovenous malformation was followed by a successful twin gestation.
