[A case of aneurysmal dilatation of a saphenous vein graft for subclavian aneurysm in a patient with Behçet disease].

The autogenous saphenous vein is the preferred conduit for repair of occluded arteries in the limb and coronary arteries. The aneurysmal dilatation of the vein graft is a unusual complication in the long-term period. A case of aneurysmal formation of the vein graft for the subclavian aneurysm 5 years after grafting with classic Behçet disease was reported. The etiology of this rare complication and the special surgical problem were also discussed.
