thromboangiitis obliterans

Etymology: Gk, thrombos + angeion, vessel, itis, inflammation; L, obliterare, to cancel

an occlusive vascular condition, usually of a leg or a foot, in which the small and medium-sized arteries become inflamed and thrombotic. Early signs of the condition are burning, numbness, and tingling of the foot or leg distal to the lesion. Phlebitis and gangrene may develop as the disease progresses. Pulsation in the limb below the damaged blood vessels is often absent. The goal of therapy is to avoid all factors that decrease the blood supply to the extremity, such as cigarette smoking, and to use all means possible to increase the supply. Amputation may be necessary if the condition progresses to gangrene with chronic infection and extensive tissue destruction. Men are affected more often than women; most affected men smoke and are between 20 and 40 years of age. Also called Buerger's disease.
