甲状腺动脉栓塞治疗甲亢的初步临床研究

目的 探讨新的导管技术行甲状腺动脉栓塞治疗甲亢的临床价值。材料与方法 采用自塑形软头导管超选择甲状腺动脉栓塞治疗甲亢，其中8例已追踪2－4个月，6例栓塞双侧甲状腺上动脉和一侧甲状腺下动脉，2例栓塞双侧甲状腺上动脉。结果 8例症状及体征明显改善或消失，甲状腺功能明显降低或已正常，4例已停用抗甲状腺药物，4例少量服药即保护甲状腺功能正常，无严重并发症。结论 介入治疗甲亢是一种安全，有效的新方法。自塑形软头导管技术能提高超选择插管及栓塞成功率，降低并发症。

Preliminary experience on thyroid artery embolization for hyperthyroidism.

Objective To evaluate the clinical effects of the thyroid artery embolization for hyperthyroidism with new catheter technique.Material and methods 17 cases were undergone super-selective thyroid arteries embolization with flexible-head catheter shaped by ourselves.The first 8 cases were followed up by 2-4 months.Bilateral superior thyroid arteries were embolized in 2 cases.Additionally unilateral inferior thyroid arteries were embolized in 6 cases.Results Symptoms and signs of hyperthyroidism were controlled in 4 patients and were effectively controlled through low dose antithyroid medication in another 4 patients.There was no severe complication. Conclusion Interventional therapy for hyperthyroidism is a safe and effective method,and new catheter technique may increase success rates.
