Postpartum hemorrhage (PPH) is the leading cause of maternal mortality worldwide. The common causes of primary PPH include uterine atony, abnormal placentation, retained placenta, and birth canal injury. The inferior mesenteric artery (IMA) arises from the aorta and is the main artery to supply the descending and sigmoid colon, as well as the rectum. We present a case of immediate, severe uterine bleeding after a normal vaginal delivery; angiography determined that hemorrhage originated from the IMA, and there were no anastomoses between the IMA and other pelvic arteries. The patient was successfully managed by selective embolization of a distal branch of the IMA. Our case report presents a new and interesting variation of pelvic vascular anatomy; moreover, it is the first report to present a case of postpartum uterine bleeding originating from the IMA.
