OBJECTIVES This study aimed to develop clinical guidelines for the management of vascular Behçet's disease (VBD) by the Behçet's Disease Research Committee of the Ministry of Health, Labor, and Welfare of the Japanese Government. METHODS A task force proposed clinical questions (CQs) concerning VBD, based on a literature search. After screening, draft recommendations were developed for each CQ and brushed up in three blinded Delphi rounds, leading to the final recommendations. RESULTS This study provides recommendations for 17 clinical questions concerning diagnosis and differential diagnoses, assessment of disease activity, and treatment. The guidelines recommend immunosuppressive treatments, for both arterial and venous involvement with active inflammation. Anticoagulation is also recommended for deep vein thrombosis except in high-risk patients. Surgical and endovascular therapies can be optional, particularly in patients with urgent arterial lesions undergoing immunosuppression. In addition, two sets of algorithms for diagnosis and treatment are shown for arterial and venous involvement. CONCLUSIONS These recommendations are expected to serve as useful tools in the daily clinical practice of Behçet's diseaseThis content has already been published in Japanese in the Guideline for the management of Behçet's disease 2020 and is submitted with permission from both the primary and secondary publishers.
