Abstract
Head and neck surgeons hesitate to resect the carotid artery because of the postoperative risk of neurologic sequelae. However, there is no curative therapeutic option for head and neck neoplasms involving the carotid artery, with the exception of complete tumor removal. To evaluate the benefits and risks of carotid revascularization techniques in locally advanced head and neck tumors we performed a retrospective analysis in an institutional, tertiary care medical center. Seven patients (5 males, 2 females) with a median age of 58 years underwent en bloc removal of locally advanced head and neck tumors, including carotid resection and revascularization, in the University of Vienna General Hospital, over a 15-year period. In six patients carotid reconstruction was accomplished by bypass grafting (five autologous grafts, one synthetic graft) and in one patient angiopatchplasty was used. There were no perioperative neurologic complications or deaths. Survival was >12 months in 5/7 patients; the other 2 patients died within 6 months due to untractable progression of cancer. We conclude that carotid revascularization techniques offer the possibility of better local control for advanced head and neck tumors without additional risks of neuromorbidity or mortality.
