摘要


目的:研究新型冠状病毒(coronavirus disease2019,COVID-19)感染患者发生下肢深静脉血栓(deep vein
thrombosis,DVT)的危险因素。方法:本研究采用单中心回顾性病例对照研究方法,纳入重庆医科大学附属永川医
院2022年12月5日-2023年1月19日入院的COVID-19患者,以发生DVT为研究终点,根据下肢血管彩超将患者分
为DVT组与非DVT组,分析与患者发生DVT相关的可能危险因素。结果:单因素相关性检验结果显示,DVT组较
非DVT组更高龄,且更多入住监护室,住院日显著延长,PT活动度、白蛋白明显降低,白细胞计数、中性粒细胞数、
降钙素原、凝血酶原时间、D-二聚体、国际标准化比值显著升高。多元logistic回归分析显示,年龄、住院日、白细
胞计数、D-二聚体是新冠感染患者发生DVT的独立危险因素,年龄(OR,1.184;95% CI 1.091-1.286,P<0.001),
住院日(OR,1.141;95% CI 1.038-1.253,P=0.006),白细胞计数(OR,1.272;95% CI 1.007-1.606,P=0.043),D-
二聚体升高(OR,1.279;95% CI 1.055-1.550,P=0.012)。结论:高龄、长住院日、高D-二聚体、白细胞计数升高
是新型冠状病毒感染患者发生DVT的独立危险因素,为预防DVT提供一定的指导意义。
