Abstract:

Postpartum uterine necrosis is a rare condition, with only a few cases reported in the literature. It is closely associated with uterine ischemia and bacterial infections, with a poor prognosis, often necessitating hysterectomy. Uterine artery embolization, uterine compression suturing, and pelvic vessel ligation are important methods for managing refractory postpartum hemorrhage, primarily by interrupting uterine blood flow to achieve hemostasis. However, the combined use of multiple hemostatic techniques can often lead to uterine ischemia. If the patient also has concurrent genital tract inflammation, the infection may be exacerbated, leading to uterine necrosis and posing a potential risk of mortality. Currently, there is no standardized treatment protocol for postpartum uterine necrosis. Multidisciplinary team management can facilitate early identification and timely control of the condition, thereby preventing severe complications. Improving uterine blood flow and actively controlling infections are critical for preventing uterine necrosis. This article discusses the risk factors, preventive strategies, and clinical management approaches for postpartum uterine necrosis. The aim is to enhance obstetricians ' abilitity of identifying

risks and manage complications, thereby protecting maternal reproductive function and ensuring life safety.
