Upper-airway obstruction as a complication of oral anticoagulation therapy.
We treated a patient for warfarin-induced sublingual hematoma causing upper-airway obstruction. This complication of oral anticoagulation therapy is rare; only three other cases have been reported in the English literature. All reported patients developed acute respiratory embarrassment necessitating emergency airway establishment. Sublingual hematomas usually resolve spontaneously, and surgical drainage is rarely necessary.
