Introduction
Lower extremity venous insufficiency is a significant health problem with economic and sociological consequences, lowering the quality of life, and sometimes leading to serious complications. The aim of this study is to evaluate the cytomegalovirus (CMV) effect on chronic inflammation in the aetiology of chronic venous insufficiency.

Material and methods
Between November 2017 and August 2018, 468 patients who underwent radio-frequency ablation therapy and phlebectomy were included in the study. PCR analyses for CMV DNA were performed on the venous tissue samples. Patients with post-thrombotic syndrome were excluded from the study. After ethical approval, the relationship between the presence of CMV DNA, gender, body mass index, and bilaterality of chronic venous insufficiency were investigated.

Results
When the relationship between CMV DNA and gender or body mass index was examined, a significant relationship was not detected. But when the patients with bilateral chronic venous insufficiency and patients with unilateral chronic venous insufficiency were compared regarding CMV DNA positivity, the patients with bilateral chronic venous insufficiency had significantly higher CMV DNA positivity (p = 0.002). Also, the incidence of venous ulcers in the CMV DNA exposed group was significantly higher.

Conclusions
In the literature there are many studies showing that CMV triggers atherosclerosis, but there is no study in which CMV directly produces chronic venous insufficiency. The high rates of positivity suggest that CMV, which is the basis of chronic inflammation, may be a significant factor in the aetiology of chronic venous insufficiency.
