Thickening of the wall produces progressive arterial obstruction and symptoms from inadequate blood supply to the affected part (*ischaemia). The arteries to the brain are often involved, giving rise to meningovascular syphilis. Endarteritis of the aorta may obstruct the mouths of the coronary arteries, supplying the heart. Endarteritis of the arteries to the wall of the aorta (the vasa vasorum) contributes to *aneurysm formation. The syphilitic infection may be eradicated with penicillin.... endarteritis
