Abstract: Hyperthyroidism, as an endocrine disease that may affect blood coagulation, is not commonly associated with cerebral venous sinus thrombosis in clinical practice. This paper reports the diagnosis and treatment process of a 21-year-old male patient with hyperthyroidism complicated by cerebral venous sinus thrombosis. Following comprehensive treatment, including thiamazole and anticoagulation therapy, the patient experienced significant relief from symptoms such as headaches, particularly after undergoing the crucial treatment step of endovascular interventional thrombectomy. This case emphasizes the importance of a thorough assessment of patients with hyperthyroidism and also suggests the potential value of interventional treatment in specific circumstances. Future broader research will contribute to clarifying the management and preventive measures for such complications.

摘要： 甲状腺功能亢进作为一种可能影响血液凝固的内分泌疾病，与颅内静脉窦血栓形成的关联在临床上并不常见。本文报道1例21岁男性甲状腺功能亢进并发颅内静脉窦血栓形成患者的诊治过程。患者在接受包括甲巯咪唑、抗凝治疗在内的综合治疗后头痛等症状得到明显缓解，特别是经历了血管内介入取栓这一关键性治疗步骤。本病例强调了对甲状腺功能亢进患者进行全面评估的重要性，同时也提示了在特定情况下介入性治疗的潜在价值。未来更广泛的研究将有助于制定这些并发症的管理和预防措施。
