Background: Behçet’s disease (BD) is a vasculitic multisystem inflammatory disorder. It may also involve the skin, mucosa, eyes, blood vessels, joints, gastrointestinal system, and central nervous system. Objectives: In this study, we aimed to present venous involvement data in patients followed up with a diagnosis of BD. Methods: The clinical, demographic, laboratory and medication data of 394 patients who were followed up with a diagnosis of BD in our rheumatology outpatient clinic between 2000 and 2020 were retrospectively evaluated. Results: Venous involvement was detected in 17.6% (n:76) patients who were followed up with a diagnosis of BD. 75% of the patients were male, and their mean diagnosis age was 27.1±9.9, disease duration was 14.2±6.3 years. While the thrombosis of lower extremity veins, cervical veins, and vena cava were observed in 85.5% of BD patients, superficial thrombophlebitis was found in 31.6%. Cerebral venous involvement (CVI) was evaluated in cranial involvement. Oral aphthous ulcer was found in 97.4 % of the patients, genital ulcer in 65.8%, pathergy positivity in 44.7%, papulopustular lesion in 34.2%, erythema nodosum in 40.8%. 27.6% of the patients were evaluated for hereditary thrombophilia and 5.3% (n:7) had hereditary thrombophilia. Deep venous thrombosis was found in 85.7% (6/7) of these patients, renal artery occlusion in 14.3%, pulmonary artery thrombosis in 14.3%, and cerebral venous thrombosis in 28.6%. Patients with and without venous involvement were compared in terms of clinical findings. A significant difference was observed in terms of retinal vasculitis, artery occlusion, arterial aneurysm, family history for BD and gender. In logistic regression analysis, a significant relationship was observed between venous involvement and gender, family history, retinal vasculitis, artery occlusion, arterial aneurysm (Table1).

Significant correlations exist between CVI and pulmonary artery involvement (PAI), intracardiac thrombosis and PAI. It should be recalled that lower extremity venous thrombosis is often present in these associations, and even precede them (1). References: [1]Seyahi E.
