Objective  To investigate the occurrence and the risk factors of stroke complicated by venous thromboembolism.

  Methods  A total of 2709 stroke patients who received treatment at our hospital between January 2018 and June 2021 were selected. The incidence of stroke complicated by venous thromboembolism was analyzed and the risk factors of stroke complicated by venous thromboembolism were investigated by logistic regression.

  Results  Among the 2709 stroke patients, 390 had venous thromboembolism, resulting in 14.39% incidence of venous thromboembolism. Among them, 383 patients (14.14%) had deep venous thrombosis (DVT), 4 patients (0.15%) had pulmonary thromboembolism (PTE), and 3 cases (0.11%) had DVT combined with PTE. According to the analysis of unconditional multivariate logistic regression model, age>60 years, concomitant hypertension, concomitant diabetes, bedrest time after admission≥3 days, D-dimer (D-D)≥0.95 mg/mL, triglyceride (TG)≥1.83 mmol/L, Barthel Index (BI) score≤9 points, and Padua score>4 points after admission were independent risk factors for stroke complicated by venous thromboembolism (P<0.05), while anticoagulation therapy was a protective factor (P<0.05).

  Conclusion  Stroke complicated by venous thromboembolism is associated, to some degree, with age, concomitant hypertension, concomitant diabetes, bedrest time, D-D, TG, BI score, Padua score, and whether anticoagulant therapy is administered or not. Interventions in line with relevant risk factors should be strengthened to effectively reduce the risk of stroke complicated by venous thromboembolism.
