Total parathyroidectomy and autotransplantation of parathyroid glands were performed in 9 patients and subtotal parathyroidectomy was performed in 7 patients with secondary hyperparathyroidism resulting from chronic renal failure. The detection rate of enlarged parathyroid glands by preoperative imaging was 38％ by computed tomography, 77％ by ultrasonography, and 44％ by MIBI scintigraphy. The removal rate of parathyroid glands by operation was 89％.
In order to remove supernumerary glands, we need to improve operation methods. It is appropriate that the resection of pre- and paratrachial tissues should be performed in addition to the simple parathyroidectomy in cases in which not all parathyroid glands can be found.
Key words : secondary hyperparathyroidism, parathyroidectomy, preoperative imaging
