Predictive factors for hypothyroidy after hemithyroidectomy

We conducted a retrospective review of all patients who underwent hemithyroidectomy between 2004 and 2019. Hypothyroidism was defined as a serum thyrotropin level greater than 5 mIU/L. The patients were analyzed for age, sex, preoperative and postoperative thyroid stimulating hormone (TSH), state, side, and volume of the remaining lobe, and histologic diagnosis. <br> Description of the Data and file structure <br> This is an SPSS file concerning the clinical and biological data of patients having a thyroid lobectomy <br> Postoperative hypothyroidism was defined by a TSH level &gt; 5mUI/L. We calculated the remaining volume of the gland considering that the lobe has a roughly ellipsoidal shape. A mathematical formula was adopted: Volume = π / 6 x (a x b xc) with a, b, and c representing, respectively, the length, width, and depth determined by ultrasound. We studied age, sex, preoperative and postoperative TSH levels, operated side, definitive histopathological examination, state of the remaining lobe, follow-up time and the average maintenance dose of Thyroxin for patients who needed thyroid hormone replacement anytime during monitoring. <br> <br>
