ABSTRACT
Carotid blowout often tends to be to occur in patients with HNC, recurrent tumors, and post-radiotherapy-induced necrosis or pharyngocutaneous fistulas. The reported incidence is 40% for neurologic morbidity and 60% for mortality rates associated with this complication. Patients with carotid blowout syndrome (CBS) can have a wide variety of clinical presentations due to the rupture of carotid artery, leading to acute hemorrhage or exposure of the carotid artery. The reported incidence is 4.3% for carotid rupture after radical neck dissection (RND). Ligation of the internal carotid artery or common carotid artery surgically is the traditional management for carotid body syndrome.
