Carotid stenting for impending carotid blowout: suitable supportive care for head and neck cancer patients?

Abstract

Carotid blowout (CB) represents a dramatic end-of-life situation for palliative head and neck cancer patients, their relatives and caregivers. Recently, endovascular therapy has been proposed for head and neck surgical patients. Preliminary reports showed a better outcome with less morbidity compared to the previous treatment modalities. However, the specific use of such techniques for palliative head and neck cancer patients has not been previously described. Retrospective review of two cases of head and neck cancer patients receiving palliative care, presenting with a CB, managed with endovascular stent placement. Bleeding was effectively stopped by the procedure in both cases. Both patients developed a post-procedure thromboembolism, which was immediately treated by appropriate anticoagulation therapy. Neurological symptoms resolved within 24 hours allowing rapid hospital discharge. One patient died at home seven months later. The second patient is alive five months after the procedure. No recurrence of CB occurred in either patient. Endovascular stent placement for CB allows a rapid arrest of bleeding and permits the use of anticoagulation therapy in order to avoid long-term neurological injury. In our view, carotid stenting should be considered as valid supportive care for palliative head and neck patients presenting with a CB.
