恶性肿瘤患者下腔静脉滤器的应用研究

目的研究下腔静脉滤器在恶性肿瘤患者中的应用,探讨其在预防肺栓塞发生中的作用。方法回顾性分析1998年至2004年,经病理学或细胞学确诊为恶性肿瘤,并于治疗前存在血栓栓塞性疾病的37例患者,安放下腔静脉滤器后肺栓塞的发生情况。结果下腔静脉滤器全部安全置入下腔静脉内,随访1～36个月,滤器无移位,无肺栓塞发生。结论对恶性肿瘤合并血栓栓塞性疾病的患者放置下腔静脉滤器,能安全有效地预防肺栓塞的发生。

Percutaneous transfemoral placement of inferior vena cava filter to prevent pulmonary embolism in patients with malignant tumor

Objective To evaluate the effectiveness and safety of inserting an inferior vena cava filter to prevent the pulmonary embolism (PE) due to detachment of the thrombus in the lower extremities. Methods Inferior vena cava filter were placed in 37 patients with malignant tumor and deep venous thrombosis from 1998 to 2004.Malignancy was confirmed by pathological or cellular biological examination in all cases.The episode of pulmonary embolism was monitored during a post- intervention follow- up. Results All the filters were placed in the inferior vena cava safely via a percutaneous femoral venous access. No serious complications such as pulmonary embolism occurred during the follow- up periods. Conclusion The inferior vena cava filter placement is an effective and safe procedure in preventing the pulmonary embolism in patients with malignant tumor and deep venous thrombosis. [
