Parathyroidectomy (PTX) is an effective way to correct calcium and phosphorus metabolic disorders and decrease aortic calcification in hemodialysis patients with secondary hyperparathyroidism (SHPT), new findings suggest. PTX also can improve arterial stiffness.

Researchers at Air Force General Hospital Beijing, China, studied 20 hemodialysis patients who underwent PTX. They compared calcium, phosphorus, calcium-phosphorus product, and parathyroid hormone (PTH) values and coronary artery calcification (CAC) scores and before and 1 year after the procedure.

All patients had CAC. Mild (score 11–100), moderate (101–399), and severe CAC (400 or more) were present in 1, 11, and 8 patients, respectively. Mean serum calcium levels decreased from 2.44 mmol/L before PTX to 2.15 mmol/L at 1 year post-procedure, a team led by Lide Lun, MD, reported in the Asian Journal of Surgery. Mean serum phosphorus levels decreased from 2.50 to 1.67 mmol/L. Mean serum calcium-phosphorus product decreased from 73.30 to 43.31. Mean intact PTH decreased from 1708.72 ng/L to 110.11 ng/L.
