Introduction/Objective: Deep vein thrombosis (DVT), once rare, has become frequent in Africa. The aim of this study was to identify factors associated with the recurrence of deep vein thrombosis.

Methodology: We conducted a descriptive and analytical cross-sectional study from 01 January 2020 to 31 December 2024 at the Bogodogo University Hospital in the cardiology department. Patients admitted to the department for deep vein thrombosis on venous echodoppler were included. Epidemiological, clinical and paraclinical parameters were crossed in a univariate and then multivariate analysis.

Results: During the study period, 164 cases of deep vein thrombosis were recorded out of 2637 hospitalised patients, giving a hospital prevalence rate of 6.22%. The mean age was 51.4 years. There was a predominance of women, 90 (55%), with a sex ratio of 0.8. Recurrences occurred in 27.44% of cases (n=45). A sedentary lifestyle, a personal history of DVT, and obesity were the most frequent thromboembolic risk factors. Multivariate analysis showed that personal history of DVT (OR=3; p=0.03), obesity (OR=3.8; p=0.005) and femoral location of thrombus (OR=2; p=0.004) were significantly associated with recurrence of deep vein thrombosis.

Conclusion: Recurrences of deep vein thrombosis are becoming increasingly frequent, and their management requires accurate identification of the risk factors.
