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. Description of the Data and file structure This is an SPSS file concerning the clinical and biological data of patients having a thyroid lobectomy Postoperative hypothyroidism was defined by a TSH level > 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.
