Abstract

Inferior thyroid artery (ITA) rupture is rare and may progress to life-threatening conditions. We present a patient who visited the emergency department after an episode of syncope and dizziness in which he had a mechanical fall that resulted in abrasions and a hematoma to his left forehead. The patient presented with dysphagia and anterior neck swelling that progressed rapidly into airway compromise requiring endotracheal intubation. Emergent computed tomography revealed a large retropharyngeal hematoma, with active arterial extravasation that was thought to be arising from the thyrocervical trunk on the left. The hematoma measured approximately 6.7 cm transversely and 3.2 cm anteroposteriorly and extended from the level of the lower nasopharynx, down the neck into the retropharyngeal and danger space and into the mediastinum posterior to the esophagus, overall approximately 25 cm. The larynx was deviated anteriorly and there was esophageal compression. An emergent arteriogram and catheterization confirmed bleeding from branches of the ITA, and successful embolization was performed. It is important to recognize the ITA rupture as a potential etiology of an acute airway compromise. In emergent situations, while securing an airway is a priority, rapidly initiating diagnostic testing to confirm the diagnosis and arranging for arterial embolization can be life-saving.
