title: Upper airway obstruction induced by warfarin sodium.
abstract: I report a patient in whom warfarin sodium induced upper airway obstruction secondary to a spontaneous nontraumatic hemorrhage into the sublingual space. Treatment of this obstructive sublingual space hematoma with conservative medical management is reviewed. I discuss the role of warfarin sodium in coagulation and in the production of this pseudo-Ludwig phenomenon.
