下肢深静脉血栓高危因素分析

Discussion of the risk factors of deep vein thrombosis in lower limbs

目的:探讨下肢深静脉血栓(LDVT)形成的危险因素。方法:选取解放军总医院2010年11月—2011年2月下肢深静脉血栓住院患者484例,采取完全随机抽样方法选取同期无血栓及血栓史的患者462例作为对照组。分析下肢深静脉血栓发生的相关因素,进行多因素非条件Logistic回归分析。结果:Logistic回归分析结果表明,肺部肿瘤(u=4.399)、盆腔肿瘤(u=1.986),近期接受骨关节手术(u=2.041)、盆腔手术(u=2.052),骨折或软组织损伤(u=2.147)、关节炎症(u=1.976)是下肢深静脉血栓的高危因素(P<0.05)。结论:对具有上述高危因素的患者要积极采取措施,预防下肢深静脉血栓的发生。

Objective：To analyze the risk factors associated with lower limbs deep venous thrombosis（LDVT）. Methods.. The data of 484 cases with LDVT visited General Hospital of PLA from November 2010 to February 2011 were analyzed, and a cohort of 462 cases without thrombosis or thrombosis history in the same period served as controls by complete random sampling method. A survey of the related risk factors of LDVT was performed, and a multivariate and unconditioned logistic regression analysis was performed. Result： The high-risk factors of LDVT were lung tumor（u=4. 399）, pelvic tumor（u=1. 986）, joint surgery（u=2. 041）, pelvic surgery（u=2. 052）, bone fracture or soft tissue injury（u=2. 147）, joint inflammation（u=1. 976）, all P〈0.05. Conclusion： It is necessary to take preventive measures to prevent LDVT in the patients with the above risk factors.
