RESUMO
OBJECTIVES: Phlebosclerosis is a fibrous degeneration of the vein wall, predominantly the intima, with or without calcification. The prevalence and etiology of phlebosclerosis of the great saphenous vein are not well documented. This study aimed to estimate the prevalence and define the risk factors of phlebosclerosis of the great saphenous vein. METHODS: The study was conducted on 300 volunteers who underwent duplex ultrasound. Volunteers with symptoms and signs of acute or chronic venous disease or known varicose veins, thrombosis, chronic vein insufficiency, and any operation in the lower extremities were excluded. The imaging hallmarks of phlebosclerosis include wall brightness, calcification, and increased wall thickness. Demographics of the volunteers (sex, age, weight, and height), Body Mass Index (BMI) and the presence of smoking, hypertension, diabetes mellitus, and dyslipidemia were recorded. Data obtained were consolidated and statistically evaluated using SPSS Version 16. RESULTS: Of the 300 volunteers who underwent duplex ultrasound, 60.3% were females, and 39.7% were males. The mean age was 60 ± 13, while the mean BMI was 26.01 ± 4.76. Moreover, 66.3% were non-smokers, and 62.3%, 81.3%, and 58.7% did not suffer from hypertension, diabetes mellitus, and dyslipidemia, respectively. The prevalence of phlebosclerosis was found to be 2.3%. Hypertension was a risk factor for the development of phlebosclerosis (p = 0.045). Moreover, there was a link between phlebosclerosis and age, as volunteers with phlebosclerosis were older than volunteers without phlebosclerosis (74.2 vs 59.11 years, p < 0.001). CONCLUSIONS: The prevalence of phlebosclerosis of the great saphenous vein is low, specifically 2.3%. Hypertension and increased age are risk factors for the development of phlebosclerosis. Both sexes are equally affected, while BMI, smoking, diabetes mellitus, and dyslipidemia do not contribute to the development of phlebosclerosis.
