新型冠状病毒肺炎（COVID⁃19）严重危害人类的健康。随着研究的深入，COVID⁃19 患者中异常的凝血功能和静脉血栓栓塞（VTE）并发症逐渐引起重视。本文将综述COVID⁃19患者D⁃二聚体升高的临床价值和VTE并发症的研究进展，同时我们结合现有研究总结新型冠状病毒（SARS⁃CoV⁃2）诱导血栓形成的可能机制，以期为预防COVID⁃19患者严重血栓事件的发生提供帮助。

Coronavirus disease 2019（COVID⁃19）caused a global pandemic and seriously endangeredhuman health. With the deepening of research，the abnormal coagulation function and venous thromboembolism（VTE）complications in COVID⁃19 patients have attracted the attention of many researchers. We review，in thisarticle，the clinical value of elevated D⁃dimer in COVID⁃19 patients and related research on VTE and summarizethe possible mechanism of thrombosis induced by SARS⁃CoV⁃2，hoping to provide reference for the prevention ofthrombosis in COVID⁃19 patients.
