title: Rare treatment of radiation induced carotid pseudoaneurysm and ensuing carotid blowout syndrome with placement of multiple contiguous endovascular stents: a case report.
abstract: Cervical radiotherapy for treatment of head and neck cancer can result in the delayed carotid vasculopathy. Surgical management for an ensuing hemorrhage is challenging due to the associated high mortality and morbidity. We present a case of a relative rapid formation of common carotid pseudoaneurysm formation with subsequent carotid blowout syndrome in previously irradiated neck. Successful treatment in our patient is highlighted by the fact that multiple, contiguous endovascular stents were placed emergently to obtain control of pseudoaneurysm rupture.
