Introduction Chronic venous insufficiency (CVI) is a common disease affecting millions worldwide. Age, obesity, female gender, sedentary life, and long-standing at work causing orthostasis have been identified as predisposing factors. Objective The visceral adiposity index (VAI) is an important indicator of abdominal obesity. Various studies in the cardiovascular field have shown that it may be more predictive than body mass index (BMI). Methods A total of 171 consecutive patients diagnosed with low-grade (C0–C3) superficial primary CVI in our clinic, between November 2021 and December 2022, were included in this prospective study. Venous Clinical Severity Score (VCSS) values were calculated. The patients were divided into two groups according to their VCSS values (Group 1: VCSS ≤6 and Group 2: VCSS >6). Results There were 110 patients in Group 1 with a median age of 42 (18–50) years. There was no difference between the groups in terms of gender, smoking, hypertension frequency, height, weight, body mass index, hemoglobin values, lymphocyte, neutrophil, mean platelet volume, urea, creatinine, high-density lipoprotein, low-density lipoprotein, triglyceride, and total cholesterol values ( p > .05). Multivariate logistic regression analysis was performed to reveal the predictive factors of high VCSS values in patients. As a result of the analysis, VAI (Odds Ratio (OR): 1.775; 95% Confidence Interval (CI): 1.389–2.269; p < .001) and CRP (OR: 2.641; 95% CI: 1.431–4.875; p = .002) values were identified as independent predictors in predicting high VCSS values. Conclusion This current study showed that high VAI values affect clinical complaints in patients with low-grade CVI. In line with our results, clinical recommendations can be made to reduce VAI values in low-stage CVI patients.
