Objective: The preoperative and postoperative calcium, parathormone levels, platelet counts, mean platelet volume values of the patients were compared in order to investigate the changes in the risk of atherosclerosis and coronary artery disease in parathyroidectomy. Method: Twelve male and 43 female patients who underwent parathyroidectomy between 01.01.2008 and 01.01.2018 at the Cumhuriyet University Surgical Oncology Clinic were included in the study. On the tenth preoperative and postoperative day, blood was drawn for the platelet, mean platelet volume, calcium and parathyroid hormone levels after a fasting period of twelve hours. The preoperative and postoperative calcium, parathormone levels, platelet counts, mean platelet volume values of the patients were compared in order to investigate the changes in the risk of atherosclerosis and coronary artery disease in parathyroidectomy. Results: The mean pre-operative blood calcium levels of the patients included in the study were 10.75 ± 1.49 mg / dl, . Mean postoperative blood calcium level was 8.59 ± 1.14 mg / dl. The mean preoperative mean platelet volume of the patients was 26.1 ± 121.55 fL, Postoperative mean platelet volume was 9.36 ± 1.26 fL. The mean preoperative parathormone level was 535,08 ± 711,08, The mean postoperative parathyroid hormone level was 74.47 ± 128.02 pg / ml. The mean preoperative blood platelet count of the patients included in the study was 418000 ± 8000 / mm³, The mean postoperative blood platelet count was 252000 ± 7000 / mm³. Conclusions: In our study, we found that the decrease in serum parathormone level, serum platelet level, mean platelet volume, after parathyroidectomy was statistically significant. Mean platelet volume and platelet count were decreased after parathyroidectomy, which are indicators of atherosclerosis and coronary artery disease; Parathyroidectomy reduces the risk of atherosclerosis and coronary artery disease. Additional clinical and laboratory studies are needed to support the risk of atherosclerosis and coronary artery disease after parathyroidectomy.
