Abstract:
Objective This study aims to evaluate the safety and efficacy of internal carotid artery(ICA)embolization for the resection of head and neck tumors invading the ICA.Methods A retrospective analysis was conducted on eight patients with ICA-invading head and neck tumors treated between August 2022 and June 2024 in Beijing Tongren Hospital,Capital Medical University.All patients underwent a preoperative balloon occlusion test(BOT),which yielded negative results before undergoing ICA embolization.Parameters from BOT,technical success rates of embolization procedures,perioperative complications,and follow-up outcomes were recorded.Results During BOT assessments,the mean reflux pressure was found to be 75.4％±10.3％of the pre-occlusion pressure.Patency of both anterior and posterior communicating arteries was observed in three cases;four cases exhibited patency solely in the anterior communicating artery,while one case showed patency only in the posterior communicating artery.The technical success rate of embolization was 100％.One patient experienced acute cerebral infarction following embolization treatment,while two patients had migraine attacks post-procedure.All patients achieved complete tumor resection without new-onset neurological deficits.Conclusion For patients with head and neck tumors invading the ICA who are negative on BOT,preoperative ICA embolization is a safe and feasible approach that enhances surgical safety during tumor resection.
