Why the study?
Carotid blowout syndrome is a rare, life-threatening complication in heavily treated head and neck cancer patients where outcome depends on early diagnosis and prompt intervention.
Highlights the use of emergent endovascular treatment for managing life-threatening carotid blowout syndrome in a patient with prior irradiation.
May support endovascular repair in post-irradiation carotid blowout; leaves open need for prospective validation before practice change.
Carotid blowout syndrome is a rare but life-threatening complication in heavily treated head and neck cancer patients whose outcome depends on early diagnosis and prompt intervention. This report describes the case of a patient with prior irradiation who underwent emergent endovascular treatment after rupture of a 2.9cm external carotid artery branch pseudoaneurysm.
