Treatment of Buerger disease (thromboangiitis obliterans) with bosentan: a case report

Abstract
Buerger disease (thromboangiitis obliterans) is a non-atherosclerotic segmental inflammatory disease strongly associated with tobacco use, and it affects small and medium-sized blood vessels in the upper and lower extremities. The only known treatment for this disease is complete discontinuation of tobacco use. This report describes the case history of a woman with Buerger disease treated with the oral dual endothelin receptor antagonist bosentan. It is believed that this is the first description in the literature of this use for bosentan.
