Uterine Artery Pseudoaneurysm After Cesarean Section: A Rare Cause of Delayed Postpartum Hemorrhage

Uterine artery pseudoaneurysm represents a rare but grave complication arising from Cesarean sections, often precipitating delayed postpartum hemorrhage. Herein, we present the intricate case of a 32-year-old gravida 3 para 2 patient who, despite initial management with tranexamic acid and blood transfusions, encountered recurrent episodes of significant vaginal bleeding one week following an emergency Cesarean delivery. Subsequent investigations unveiled the presence of a uterine artery pseudoaneurysm, accentuating the diagnostic intricacies and evolving therapeutic strategies associated with this condition. While ultrasound serves as a cornerstone in diagnosis, computed tomography angiography (CTA) emerged as pivotal in delineating the pseudoaneurysm in this instance. Timely recognition and intervention, including image-guided embolization, stand imperative in averting the potentially dire consequences of uterine artery pseudoaneurysm. This narrative underscores the necessity of incorporating UAP into the differential diagnosis of delayed postpartum hemorrhage, particularly post-Cesarean sections.
