[Endothoracic vascular involvement in Behçet's disease].

The observation of 3 cases has prompted the authors to review the characteristics of vascular abnormalities that may be found in Behçet's disease. These lesions, the frequency of which has diversely been estimated, involve the veins more often than the arteries. Arterial lesions occur, after a varying length of time, as occlusions or aneurysms, both treated by surgery. Phlebitis and venous thrombosis may be complicated by severe pulmonary embolism and therefore require anticoagulant therapy.
