Vascular manifestations on Behcet's disease (BD) vary from 25 to 65% according to different series. Affects both arteries as veins, but superficial thrombophlebitis is the most frequent disorder. Disorders with higher morbidity like deep venous thrombosis, and arterial aneurisms can appear, even in the lungs. In our series of 30 patients we found an incidence of 46% of vascular manifestations, mainly (92%) superficial thrombophlebitis. We highlight the presence of a femoral aneurism, which was resected, and discuss its evolution and response to treatment with prednisone and cyclophosphamide. We review in-depth the vascular manifestations in the Spanish and International scientific literature, paying special interest to aneurism dilatations.
