【摘要】 目的：探讨甲亢术后复发原因、术后复发率、提高再次手术疗效和减少合并症的方法。方法：对１２例术后复发甲亢行再手术治疗的资料进行了回顾性分析。结果：复发主要因首次手术保留腺体过多、椎状叶未切除或末切断甲状腺动脉。再手术的困难是解剖模糊、粘连严重、渗血明显。再手术前要控制好甲亢症状，防止损伤甲状旁腺和喉返神经及颈部动静脉，采用甲状腺前内侧和前外侧之间囊内切除可防止损伤，屎留组织控制在４～８ｇ，保证术后引流通畅，必要时预防性气管切开。结论：甲亢术后复发再手术是治疗的重要方法。更多还原

【Abstract】 Objective : To investigate the couses of recurrence of hyperthyroidism after subtotal thyroidectomy and expect to reduce the possibility of relapse, improve the curative effect and reduce complications of reoperation. Methods:Retrospectively analyzed 12 cases of hyperthyroidism after subtotal thyroidectomy. Results:The main couses of relapse were too much tissue of thyroid was reserved, pyramidal lobe was not ablated and the artery of thyroid was not ligated. It was vital to control the symptoms of hyperthyroidism preparatory to reoperation. The difficulties of sdreoperation were vagal nerve anatomic structure and serious hemorrhage when dissection. The injuries of parathyroid,recurrent laryngeal nerve and cervical vessal must be avoided. To prevent injuries, it was better to ablate in sack of thyroid, expeoring between front-medial and front-lateral of gland. It was recommended to reserve 4-8 grams enyroid tissue it was vital to drain smoothly and prophylatic tracheotomy when necessary. Conclu-sion : it is valuable to undertake second subtotal thyroidectomy in order to eliminate hyperthyroi- dism after subtotal thyroidectomy.更多还原
