AbstractPostpartum hemorrhage (PPH) affects approximately 14 million women yearly, accounts for 25% of delivery-related deaths in the world and is the main cause of emergency peripartum hysterectomy. Traditionally, PPH is defined as at least 500 mL of blood loss after vaginal delivery or 1000 mL of blood loss after cesarean-section. However, several authors have suggested a simpler definition to include women who experience hemodynamic instability after birth regardless of amount of blood loss. Secondary PPH is defined as bleeding that occurs after 24 hours to 12 weeks from delivery, and can fail medical management. It is imperative that the clinical team recognize the signs and symptoms of secondary PPH and, if necessary, consult the interventional radiology service for a minimally invasive option of uterine artery embolization, which has shown up to 95% success rate.Published by Elsevier Inc.
