Pseudo aneurysm of the uterine artery with arteriovenous fistula after cesarean section: A rare but sinister cause of delayed postpartum hemorrhage

Abstract

Pseudoaneurysm of the uterine artery is a rare complication of cesarean section. Delayed diagnosis and management may result in rapid and catastrophic postpartum hemorrhage and may necessitate hysterectomy or can even be fatal. A 28-year-old woman (gravida I, para I) presented with delayed postpartum hemorrhage 10 days after emergency cesarean section. Using transabdominal and transvaginal Color Doppler sonography, we detected a pseudoaneurysm in the posterior uterine wall, which was successfully treated with selective embolization distal and proximal to the lesion with platinum coils. In patients with delayed postpartum hemorrhage-especially after cesarean section-the rare possibility of uterine artery pseudoaneurysm must be kept in mind.
