Background |
The evaluation and treatment of hyperfunctioning mediastinal parathyroid gland(s) (MPG) is evolving. This study reports our overall experience with MPG in a tertiary referral center.
Methods |
A prospective database of 922 patients undergoing parathyroidectomy by 2 surgeons from 1982 to 2005 was reviewed.
Results |
Thirty-two of 922 (3.5%) patients had MPG. Nine (28%) patients had a prior failed parathyroidectomy. Sestamibi and computed tomography scans were correctly positive in 24/28 (86%) and 6/7 (86%) patients, respectively. MPGs were removed via cervical approach in 22 (69%). Eleven of 22 patients had a focused cervical approach. Nine MPGs required a limited sternotomy (n = 3) or a successful radioguided video-assisted thoracoscopic approach (VATS, n = 4) for removal. Two VATS were converted to a full sternotomy. One patient refused surgery. All patients who required sternotomy/VATS had MPGs caudal to the innominate vein. Twenty-nine of 31(94%) patients were cured. Two are stable on calcimimetics. One patient has permanent hypoparathyroidism.
Conclusions |
Most MPGs can be removed through a cervical approach. Preoperative Sestamibi and computed tomography scans can help the surgeon plan the best initial surgical approach. Those below the innominate vein require a thoracic procedure, preferably a radioguided probe-assisted thoracoscopic resection with intraoperative parathyroid hormone (ioPTH). An alternative to surgical removal is medical treatment.
