Background and Clinical Significance: Postpartum hemorrhage (PPH) is a leading cause of maternal mortality worldwide. Among its various etiologies, uterine atony accounts for approximately 70% of cases, while other causes include genital tract trauma, pathologic placentation, and intrapelvic arterial injury. Uterine artery embolization (UAE) has emerged as a preferred management option for severe PPH due to its high success rates of 89-98% and fertility preservation benefit. Despite its efficacy, UAE can lead to complications, such as pain, re-bleeding, infection, persistent vaginal discharge, ovarian insufficiency, and uterine necrosis-a rare but serious complication occurring in 1.4-2.7% of cases. Case Presentation: We present three cases of uterine necrosis following UAE from a single center (CHA Bundang Medical Center) between 2003 and 2024. All patients developed persistent high-grade fever approximately two weeks after the procedure, despite an initial response to antibiotic therapy. Imaging studies, including contrast-enhanced CT and MRI, revealed uterine ischemia and necrosis, and all patients ultimately required total hysterectomy. Conclusions: Uterine necrosis is a rare but potentially life-threatening complication of UAE that should be suspected in patients with persistent high-grade fever beyond the typical post-procedural course. Early imaging evaluation, particularly with contrast-enhanced modalities, is essential for prompt diagnosis. Timely surgical intervention, including hysterectomy, may be required to prevent severe morbidity.
