Spontaneous Sublingual Hematoma Caused by Warfarin Toxicity: A Case Report.

Objective: Anticoagulation therapy is an exceptionally effective approach for preventing thromboembolic events, including both primary and secondary occurrences that can significantly affect patient health. Among the range of anticoagulants available for clinical use, warfarin is particularly prominent, having gained extensive recognition and acceptance within the medical field for its demonstrated efficacy in treating coagulation disorders. One of the main adverse effects linked to warfarin administration is the heightened risk of bleeding, which can present in various forms. However, it is important to note that sublingual hematoma remains a relatively rare complication, though it has the potential to cause serious airway obstruction if it occurs. In situations where a patient shows symptoms of an unstable airway due to such complications, performing an urgent surgical procedure, which may involve interventions such as tracheostomy-to restore airway patency and ensure sufficient ventilation is typically recommended. Case Presentation: This report outlines a clinical case involving a 69-year-old male patient who developed a sublingual hematoma as a direct result of warfarin therapy, which subsequently led to airway obstruction. Conclusion: Sublingual hematoma is a rare but potentially life-threatening complication of anticoagulation therapy. Early recognition, prompt airway management, and rapid reversal of coagulopathy using available resources are critical to preventing fatal airway obstruction in the emergency setting.
