Uterine artery pseudoaneurysm is a rare but serious complication of pelvic surgery (although there are some cases reported following normal delivery), which can manifest as a severe bleeding in the postoperative period. Doppler ultrasound has an important role in the differential diagnosis of the causes of postpartum hemorrhage, and should guide us to this rare complication that can benefit from treatment by uterine artery angiographic embolization. Pseudoaneurysm is typically diagnosed by symptoms associated with the rupture, causing hemorrhage. It can also be asymptomatic, may thrombose, or may cause pain. We report the case of a uterine artery pseudoaneurysm diagnosed in the second episode seven weeks after cesarean delivery.
