Precipitous delivery may lead to serious maternal and neonatal complications. Uterine artery pseudoaneurysm is one of the causes of delayed postpartum hemorrhage. Here, we describe three cases of uterine artery pseudoaneurysm manifesting as delayed postpartum hemorrhage after precipitous delivery. Duration of second stage of labor in case 1, 2, and 3 was 15, 15, and 60 minutes, respectively. Excessive vaginal bleeding occurred 10, 9, and 31 days after delivery, respectively. Ultrasonogram and pelvic angiography revealed the uterine artery pseudoaneurysm in each case and uterine artery embolization was performed. Uterine artery pseudoaneurysm may be a complication of precipitous delivery.
