Imaging in Uterine Artery Pseudoaneurysm: A Rare, Potentially Fatal Cause of Secondary Post-partum Hemorrhage

Abstract

Secondary postpartum hemorrhage is one of the important cause of postpartum morbidity and mortality. Uterine artery pseudoaneurysm is a rare, potentially fatal but treatable cause of secondary post-partum hemorrhage. If not diagnosed timely, it can lead to life-threatening hemorrhage. We report the case of a 41-year-old woman who presented with profuse vaginal bleeding on 32nd day of cesarean section. On imaging a left uterine artery pseudoaneurysm was found in the uterine wall with blood clots in the uterine cavity. Patient was managed with aggressive fluid resuscitation and immediate interventional radiology procedure of selective embolization of pseudoaneurysm. High index of suspicion is needed to search for rare vascular causes like pseudoaneurysm.
