目的:研究在恶性肿瘤患者合并下肢深静脉血栓中置入下腔静脉滤器预防肺栓塞并进行溶栓的效果。方法:回顾性分析2003年6月至2007年4月,经病理学或细胞学确诊为恶性肿瘤,并于治疗前存在下肢深静脉血栓的20例患者安放下腔静脉滤器后肺栓塞的发生情况,12例保留导管溶栓治疗。结果:下腔静脉滤器全部置入成功,溶栓治疗有效。随访1～24个月,滤器无移位,无肺栓塞发生。结论:对恶性肿瘤合并下肢深静脉血栓形成的患者放置下腔静脉滤器可较好地预防肺栓塞发生。
Objective: To study the effect of inserting inferior vena cava filter in the treatment of patients with malignant tumor complicated with deep venous thrombosis of the lower extremity to prevent pulmonary embolism and thrombolysis. Methods: The incidence of pulmonary embolism was retrospectively analyzed in 20 patients with pathologically or cytologically diagnosed malignant neoplasms before and after the treatment of deep venous thrombosis , 12 cases retained catheters thrombolysis. Results: Inferior vena cava filters were all inserted successfully, and thrombolytic therapy was effective. Follow-up 1 ~ 24 months, no shift of the filter, no pulmonary embolism occurred. Conclusion: The placement of inferior vena cava filter in patients with malignant tumor complicated by deep venous thrombosis can prevent pulmonary embolism.
