Upper airway obstruction secondary to warfarin-induced sublingual hematoma.

Sublingual hematoma is a rare but potentially fatal complication of oral warfarin sodium. Less than ten cases are reported in the English-language literature with only two of these appearing in the otolaryngologic literature. Spontaneous bleeding into the sublingual and submaxillary spaces creates a "pseudo-Ludwig's" phenomenon with elevation of the tongue and floor of mouth and subsequent airway compromise. Two new cases, along with a review of the literature are presented. Management is directed at prompt control of the airway and reversal of the coagulopathy. Sore throat is a uniform, early complaint that should be taken seriously in any patient receiving oral anticoagulation therapy.
