Acquired Uterine Arteriovenous Malformation and Retained Placenta Increta

Uterine arteriovenous malformations are rare and have been reported to occur after uterine trauma (eg, surgery, gestational trophoblastic disease, malignancy).

A 33-year-old woman, gravida 3 para 3, presented 4 weeks post-cesarean delivery with episodic profuse vaginal bleeding. Pelvic ultrasonography and magnetic resonance imaging revealed a left uterine arteriovenous malformation. After consideration of all treatment options, total laparoscopic hysterectomy was performed.

Acquired uterine arteriovenous malformations and placental ingrowth into the myometrium are increasingly reported after surgical uterine procedures. This case of a postpartum patient with both uterine arteriovenous malformation and retained placenta increta suggests a correlation between the two complications.
