Vascular Behçet's disease (BD) would keep risk of anastomotic pseudoaneurysm due to deterioration of the disease even after vascular surgery was successfully done. Therefore, it is one of the least-welcome diseases for vascular surgeons. There still exist several points on a concept and criteria of the vascular BD which not only general practitioners but also the vascular surgeons do not understand. Clinical findings strongly suspecting vascular BD are follows; saccular aneurysms without atherosclerosis developed in younger than 50-year-old patients, superior vena cava syndrome or deep vein thrombosis in bilateral legs without apparent causes, and multiple superficial thrombophlebitis, etc. It is very difficult to make a diagnosis of BD in the patients whose onset of the disease is a vascular lesion, because vascular BD combines few ocular lesions. In such case, it is very important to find out not only oral and genital ulceration, but also past history of arthritis. To establish the vascular BD, we vascular surgeons have to collect cases of the vascular BD and to revise criteria of the disease. (This is a translation of Jpn J Vasc Surg 2017; 26: 19-23.).
