Clinical Presentation and Treatment of Thromboangiitis Obliterans With Superimposed Osteomyelitis.

Thromboangiitis obliterans (TAO) is an autoimmune vasculitis that typically presents in male smokers between the ages of 25 and 40. Although TAO primarily affects medium-sized blood vessels, it can also infiltrate small blood vessels as well as nerves and veins. The inflammation can cause segmental thrombosing and occlusion of the blood vessels leading to gangrene and eventual amputations.
