514例下肢深静脉血栓形成的发病因素分析

Etiologic Factors Analysis in 514 Cases of Lower Extremity Deep Venous Thrombosis

目的:了解下肢深静脉血栓形成(DVT)发病的临床特点及相关的危险因素。方法:对514例DVT患者的临床资料进行回顾性分析。结果:DVT易累及左侧肢体,女性20～30岁发病率大于同年龄段男性(P<0.01),常见的危险因素有年龄≥40岁(74.9%)、吸烟(47.86%)、手术(21.21%)、长期卧床或少活动(17.12%)、外伤或骨折(14.4%)、肥胖(9.53%)、妊娠/产后(8.95%)、肿瘤(6.03%)等。结论:DVT是一种多因素协同参与的疾病,早期发现危险因素和早期预防可以降低DVT的发病率。

Objective To understand the clinical characteristics of deep venous thrombosis （DVT） and its associated risk factors Methods Retrospective analysis of the clinical data of 514 cases of DVT. Results DVT usually involved the left limbs of people between 20 to 30 years old. The incidence of women was higher than that of men in the same age （P 〈 0.01）. The common risk factors contains： age≥40 years （74.9%）, smoking （47.86%）, surgery（21.21%）, prolonged bed rest or little activity（17.12%）, trauma or fractures（14.4%）, obesity （9.53%）, pregnancy or postpartum（8.95%）, tumor（6.03%）,etc. Conclusion DVT is a disease implicating many synergistic factors, early detection and prevention of risk factors can reduce the incidence of DVT.
