There have been few reports of vasodepressor carotid sinus syncope, as opposed to the cardioinhibitory type, and no definitive treatment has been described. A 58 year old man developed episodes of syncope after surgery and radiotherapy for a laryngeal tumour. The episodes were characterised by hypotension, sharp pain in the right neck, dizziness, and bradycardia. A temporary pacemaker failed to prevent the symptoms, but ephedrine and fludrocortisone produced substantial improvement. Of the four types of treatment used in carotid sinus syncope, irradiation was ruled out because the patient had had irradiation before developing syncope, surgery was inappropriate because of the laryngeal tumour, and pacing failed. Combined drug treatment with a vasoconstrictor and plasma volume expander produced an improvement in symptoms but did not eliminate them.
与心脏抑制型相反，血管减压型颈动脉窦晕厥的报道较少，且尚无明确的治疗方法。一名58岁男性在喉肿瘤手术及放疗后出现晕厥发作。发作的特点是低血压、右颈部剧痛、头晕和心动过缓。临时起搏器未能预防这些症状，但麻黄碱和氟氢可的松使症状有了显著改善。在用于治疗颈动脉窦晕厥的四种方法中，由于患者在出现晕厥之前已经接受过放疗，所以排除了放疗；由于存在喉肿瘤，手术不合适；起搏治疗失败。使用血管收缩剂和血浆扩容剂联合药物治疗使症状有所改善，但并未消除症状。
