Behçet's disease is an uncommon systemic process generally developing during the third or fourth decade of life. Recurrent inflammatory lesions are characteristic. Cardiovascular involvement, which may be arterial or venous, is rare but with particularly severe prognosis. One case of concomitant aortic and iliac aneurysms is reported. The patient underwent emergency surgery for acute rupture. Surgical revascularization was performed, mainly with prosthetic grafts, and patch aortoplasty. On the basis of this case and cases reported in the literature, it can be concluded that morbidity and mortality are high because of the etiology underlying vascular involvement in Behçet's disease.
