An uncommon cause of delayed postpartum hemorrhage is a pseudoaneurysm of the uterine artery. Pelvic arterial pseudoaneurysm is generally treated by laparotomy and hemostatic sutures or by uterine artery embolization. We describe two cases of late postpartum hemorrhage following Cesarean section, attributed to pelvic arterial pseudoaneurysm, that were successfully treated by direct thrombin injection under ultrasound guidance. Percutaneous or transvaginal ultrasound-guided direct thrombin injection is a simple procedure that does not require any sophisticated surgical or radiological equipment.
