卵巢静脉血栓（ovarian vein thrombosis, OVT）是一种罕见的静脉血栓栓塞症，多发生于剖宫产术后，因症状不典型易被漏诊或误诊。本文报道两例剖宫产后OVT病例，一例血栓延伸至下腔静脉，另一例合并肺动脉栓塞。两例患者均采用下腔静脉可回收滤器置入联合静脉溶栓及新型口服抗凝药的综合治疗策略，滤器均在两周内成功取出，规范抗凝治疗持续至少三个月，最终血栓完全吸收且无严重并发症。针对高危复杂卵巢静脉血栓病例（如下腔静脉受累及肺栓塞），本研究通过个体化介入治疗方案的探索，证实滤器置入联合抗凝与溶栓治疗可有效预防肺栓塞并促进血栓清除，为临床实践提供了新的综合干预方案。

Ovarian vein thrombosis (OVT) is a rare form of venous thromboembolism, predominantly occurring after cesarean section, and is frequently underdiagnosed or misdiagnosed due to its nonspecific clinical manifestations. This article reports two cases of postpartum OVT following cesarean delivery: one with thrombus extension into the inferior vena cava (IVC) and the other complicated by pulmonary embolism (PE). Both patients received a comprehensive therapeutic regimen involving retrievable inferior vena cava filter implantation, systemic thrombolysis, and novel oral anticoagulants (NOACs). The filters were successfully removed within two weeks, and standardized anticoagulation therapy was maintained for at least three months, resulting in complete thrombus resolution without severe complications. For high-risk, complex OVT cases (e.g., IVC involvement or PE), this study explored individualized interventional strategies, demonstrating that filter placement combined with anticoagulation and thrombolysis effectively prevents pulmonary embolism and enhances thrombus clearance. These findings propose a novel integrated therapeutic approach for clinical management.
