Venous disease progression in western Europe (VENPRO): A prospective cohort study.

Objective

A prospective cohort study aimed to determine factors which influence the progression of chronic venous disease (CVD) in an attempt to aid in the early identification of those at patients who are likely to benefit from early intervention.

Methods

A prospective cohort study of patients referred to tertiary vascular services with varicose veins over 7 years was conducted. The primary outcome measure was the rate of disease progression from time of referral to time of consultation. The secondary outcome measure was to the rate of venous complications during the same time period.

Results

1000 patients from routine varicose vein waiting lists were included in the study. The mean waiting time was 2.96 ± 1.25 years. The majority of patients were female (73% versus 27%), and the average age was 57.8 ± 14.7 years. One fifth of the cohort developed a complication or showed evidence of disease progression. Logistic regression showed that advancing age and previous episodes of cellulitis are significant risk factors for the development of CVD progression.

Conclusions

Varicose veins are more than a cosmetic issue and can be associated with substantial health and economic costs. Continuous identification of risk factors will enable clinicians to implement treatment strategies earlier for at risk patients.
