title: Case of three delayed complications of radiotherapy: bilateral vocal cord immobility, esophageal obstruction and ruptured pseudoaneurysm of carotid artery.
abstract: We report the first case of three delayed complications following irradiation for laryngeal carcinoma: bilateral vocal cord immobility, obstruction of esophagus and spontaneously ruptured pseudoaneurysm of common carotid artery. Medial fixation of bilateral vocal cords and stenosis of cervical esophagus were noted at 28 years after radiotherapy. Spontaneous rupture of a pseudoaneurysm bulging into the hypopharynx and obstruction of the esophagus occurred at 35 years after irradiation. The life-threatening hemorrhage was successfully treated by microcoil embolization of the common carotid artery. The relationship between these complications and irradiation is also discussed.
