下肢深静脉血栓(DVT)形成是指血液在深静脉内不正常凝结形成凝血块(血栓),阻塞管腔导致静脉回流障碍~([1]),与肺动脉栓塞(PTE)同属于静脉血栓栓塞症(VTE),是临床常见的周围血管疾病。其致病和诱发因素多样,具有远期危害性~([2]),如诊治不及时,容易导致下肢静脉血管完全闭塞,造成肢体溃烂,重者引起肺栓塞而危及生命~([3])。了解下肢DVT形成的相关因素及高发人群,对于早期预防、及早诊治,获得良好预后
The formation of lower extremity deep venous thrombosis (DVT) refers to the blood in the deep vein coagulation clot formation (thrombosis), obstruction of the lumen caused by venous reflux disorder [1], and pulmonary embolism (PTE) belong to the same venous thromboembolism Disease (VTE), is a common clinical vascular disease. Its pathogenesis and induced factors are diverse, with long-term hazards ~ ([2]), such as diagnosis and treatment is not timely, easily lead to complete occlusion of venous blood of the lower extremities, resulting in limb ulceration, severe cases of pulmonary embolism and endangering life ~ ([3] ). Understand the lower limb DVT related factors and high incidence of the crowd, for early prevention, early diagnosis and treatment, access to good prognosis
