{"pk":941,"title":"Extensive Upper Airway Hematoma Secondary to Supratherapeutic Warfarin Anticoagulation","subtitle":null,"abstract":"Case Presentation:\n A 63-year-old female presented to the emergency department complaining of cough, neck swelling, dysphagia, and dysphonia for two days, with a past medical history of atrial fibrillation managed with warfarin. Investigations revealed a supratherapeutic international normalised ratio (greater than 10). Imaging and endoscopic examination showed an extensive retropharyngeal hematoma with significant mass effect on the airway.\nDiscussion:\n A rare but potentially fatal complication of warfarin anticoagulation is upper airway hematoma, with violent coughing described as an inciting cause. Signs of airway compromise necessitate specialist consultation and definitive airway management, while mild cases without airway concerns can be managed conservatively with medical anticoagulation reversal.","language":"en","license":{"name":"Creative Commons Attribution 4.0","short_name":"CC BY 4.0","text":"Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.
