目的探讨甲状腺单发良性肿瘤行患侧腺叶切除术后甲状腺功能、对侧腺叶大小及血流量的变化。方法结合文献回顾性分析对甲状腺良性肿瘤行患侧叶切除的安全性进行临床评估。结果甲状腺患侧叶切除术后,对侧叶无包块复发,甲状腺功能基本正常(甲低发生率1.7%,均呈一过性,且无需替代治疗),对侧腺体体积较术前曾有轻度增大但差异无统计学意义(P>0.05);甲状腺上动脉血供明显增加(P<0.05)。结论甲状腺侧叶切除术后,对侧腺体可代偿甲状腺功能且体积无明显长大,其原因可能与腺体血供增加有关。
Objective To investigate thyroid function in benign thyroid tumors after thyroidectomy thyroid function, the size of the contralateral gland lobes and blood flow changes. Methods Combined with literature retrospective analysis of benign thyroid tumors underwent lateral resection of the safety of clinical evaluation. Results After the lateral lobectomy, the contralateral lobes showed no recurrence and thyroid function was normal (the incidence of hypothyroidism was 1.7%, all of which were transient and without replacement therapy). The volume of contralateral gland was significantly higher than that of the preoperative There was a slight increase but the difference was not statistically significant (P> 0.05); thyroid artery blood supply increased significantly (P <0.05). Conclusions After the thyroidectomy, the contralateral gland can be compensated for thyroid function and the volume did not significantly increase, the reason may be related to increased glandular blood supply.
