Development of chronic venous disease

Abstract

Development of chronic venous diseaseIntroduction: Chronic venous disease is known to gradually worsen in the course of years. However, little clinical data is available.The patient group and methods: We used the set of our patients with completed clinical examination, duplex sonography and photoplethysmography and selected 160 patients examined at our office after 10 and more years. Females represented 79% in the group. The mean age was 54 years (range 18-82 years). Venous varices in lower limbs in the family were reported by 49% patients. Venous sclerotization had been undergone by 6.3% and venous surgery by 10.6% patients. The mean body mass index was 27. We used CEAP classification. The clinical class C1 included 50 patients, C2 included 81, C3 included 15 and C4 included 14 patients. Regurgitation in superficial veins was found in 43%. The mean venous return time after physical activity was 24.5 s. Results:The last examination was performed after 13 years on average (range 10-28 years). Deterioration of the clinical condition and progression to a higher class were observed in 36% patients in class C1, in 23.5% patients in C2, in 13% patients in C3 and in 7% patients in C4. We did not demonstrate any statistically significant effect of the followed parameters on the progression of the disease. Conclusion:The progression rate of the disease in our patient group followed at the vascular office for 10 and more years is lower compared to population studies.
