Subtotal Versus Total Parathyroidectomy with Forearm Autograft for Secondary Hyperparathyroidism in Chronic Renal Failure

Forty-three patients with chronic renal failure and secondary hyperparathyroidism underwent parathyroidectomy; 20 of the 43 underwent subtotal parathyroidectomy (Group A) and 23 patients underwent total parathyroidectomy and parathyroid autotransplant in the forearm (Group B). Postoperative clinical improvement was similar in both groups. In the immediate postoperative period eight patients in Group A who had severe bone changes and 21 patients in Group B needed supplemental calcium administration. The grafted tissues in all cases functioned well; reimplantation of the cryopreserved parathyroid tissues was unnecessary. One case in each group showed a recurrence. One patient in Group A was submitted to reexploration of the neck with a lateral approach. The other patient in Group B underwent excisions of the transplanted parathyroid tissues on three separate occasions under local anesthesia. The second operation was definitely easier and safer to manage after a total parathyroidectomy with autotransplantation to the forearm.
