Learning objectives
- Recognize an expanding neck hematoma
- Management of an expanding neck hematoma
Definition and mechanism
- Hematoma is caused by blunt neck trauma leading to the dissection of a major blood vessel or bleeding from a soft tissue injury
- May result from recent surgery or spontaneous as with a ruptured thyroidal cyst, thyroidal vessel, or parathyroid adenoma
- Affects the pharynx, larynx, esophagus, and trachea and results in airway compromise
- Theoretical potential for hemodynamic instability due to compression of the carotid sinus with resulting bradycardia/hypotension
Causes
- Injuries to the internal and/or external carotid arteries, external carotid artery deep branches, or internal jugular veins
- Injuries to the cervical fascial layers (barriers of deep spaces) that facilitate the pooling of blood and hematoma
Management

Keep in mind
- Intubation may be difficult and should be performed by an experienced anesthesiologist
- In case of inability to intubate, a surgical airway should be performed early
