摘要子宫动静脉瘘（uterine arteriovenous fistula，UAVF）是一种比较罕见的血管异常疾病，可导致危及生命的严重出血，在基层医院第一时间诊断和处理较为困难。本文报道了2023—2024年诸暨市妇幼保健院妇科应用屈螺酮炔雌醇片治疗的4例UAVF的诊疗情况，结合文献回顾，系统分析了该病的病因机制、临床特征及诊疗策略，重点探讨药物保守治疗的疗效与安全性，旨在为UAVF的早期识别、精准诊断及合理干预提供临床依据，以降低大出血风险及远期并发症发生率，改善患者预后。

abstractsUterine arteriovenous fistula (UAVF), a relatively rare vascular anomaly, may lead to life-threatening hemorrhage and poses diagnostic and management challenges for primary hospitals during initial encounters. This article reports four cases of UAVF treated with Drospirenone and ethinyl estradiol tablets at Department of Gynaecology, Zhuji Maternal and Child Health Hospital between 2023 and 2024. Combined with literature review, we systematically analyzed the etiological mechanisms, clinical characteristics, and diagnostic-therapeutic strategies of this condition, with particular focus on evaluating the efficacy and safety of conservative pharmacological management. By summarizing case features and individualized treatment protocols, this study aims to provide clinical references for early identification, accurate diagnosis, and rational intervention of UAVF, thereby reducing risks of massive hemorrhage and long-term complications while improving patient prognosis.
