title: Novel pathophysiological cause for post-partum hemorrhage: Case report of post-partum hemorrhage with occult abnormal artery diagnosed on pelvic angiography.
abstract: To the best of our knowledge, this is the first report of post-partum hemorrhage (PPH) caused by an occult abnormal artery detected shortly after delivery on pelvic angiography (PAG). Initially, a diagnosis of uterine atony was made because the apparent cause of hemorrhage was not detected via the usual obstetrical examination. An abnormal artery, however, was suspected on PAG and confirmed on pathology. This case suggests a novel cause of persistent PPH resistant to obstetric management. Obstetricians should be aware that an abnormal artery may cause PPH, and that radiology may be required for diagnosis.
