Thromboangiitis obliterans

Thromboangiitis obliterans is a nonatherosclerotic inflammatory disease of small and medium arteries and veins, strongly associated with tobacco use and causing blood-vessel blockage.

Vasculitis: Inflammation of blood-vessel walls that can narrow, damage, or obstruct vessels. Thromboangiitis obliterans is a distinctive form of vessel inflammation.
Raynaud phenomenon: Episodes of reduced blood flow to the fingers or toes, often triggered by cold or emotional stress. It can accompany the disease and precede more persistent ischemia.
Atherosclerosis: A chronic disease in which plaques build up within the walls of medium and large arteries. Unlike atherosclerosis, this disease is nonatherosclerotic and typically affects distal vessels.
Tobacco cessation: Stopping the use of tobacco products and avoiding their continued use. Complete tobacco cessation is the central measure for limiting disease progression.
Leo Buerger: An Austrian-American physician who described thromboangiitis obliterans in the early twentieth century. His clinical and pathological studies established the disease as a distinct entity.
Thrombosis: Formation of a blood clot within a blood vessel. Inflamed vessels develop occlusive thrombi that restrict blood flow.
Intermittent claudication: Muscle pain caused by exertion and relieved by rest, usually due to reduced arterial blood flow. Distal arterial obstruction can cause exertional pain in the legs or arms.
Peripheral artery disease: Reduced blood flow to the limbs caused by narrowed or blocked peripheral arteries. It is the broader clinical category that includes several causes of limb ischemia.
Nicotine replacement therapy: A treatment that supplies controlled doses of nicotine to reduce withdrawal during tobacco cessation. Nicotine exposure may be problematic in this disease, so cessation options need clinical guidance.
Felix von Winiwarter: An Austrian surgeon who published an early description of a distinctive occlusive limb-vessel disease in 1879. His report preceded Buerger’s account and is part of the disease’s history.
