摘　　要：目的探讨膝上和膝下深静脉血栓与发生肺栓塞的相关性。方法回顾性分析2016年1月~2017年12月于我院彩色多普勒超声发现下肢深静脉血栓住院患者910例,并依据解剖位置分为膝上组和膝下组,分别比较两组下肢深静脉血栓的肺栓塞发生率。并依据影像学分型将肺栓塞分为大面积肺栓塞和小面积肺栓塞,分别比较两组深静脉血栓发生大面积肺栓塞的发生率。结果膝上深静脉血栓肺栓塞发生率高于膝下深静脉血栓,两者差异有统计学意义(P<0.05)。膝上深静脉血栓大面积肺栓塞(影像学分型)发生率高于膝下深静脉血栓,两者差异有统计学意义(P<0.05);其中,孤立小腿肌间静脉血栓也可以发生致死性肺栓塞。结论膝上深静脉血栓形成较膝下深静脉血栓形成更易发生肺栓塞,特别是发生大面积肺栓塞。不能忽视的是孤立的小腿肌间静脉血栓也可发生致死性肺栓塞。Objective To evaluate the correlation between the pulmonary embolism （PE） and deep vein thrombosis （DVT）. Methods We retrospectively reevaluated CTPA and color doppler ultrasound data sets for 910 patients with DVT of lower extremity during hospitalization in affiliated Hospital of Taishan Medical University from January 2016 to December 2017. DVT was divided into Above-knee deep vein thrombosis （AKDVT） and Below-knee deep vein thrombosis （BKDVT）. The PE was divided into massive pulmonary embolism （MPE） and non-massive pulmonary embolism. Chi-squared tests were performed. Results The incidence of PE and MPE was significantly higher in patients with AKDVT than with BKDVT （ P 〈0.05）. The isolated calf muscle vein thrombosis can also lead to fatal pulmonary embolism. Conclusion The incidence of PE in patients with AKDVT is higher than with BKDVT, and MPE is more likely to occur in patients with AKDVT. However, the risk of fatal pulmonary embolism in isolated calf muscle vein thrombosis should not be ignored.
