Parathyroidectomy in chronic renal failure.

A M de Francisco, H A Ellis, J P Owen

    The Quarterly Journal of Medicine
    |June 1, 1985
    PubMed
    Summary

    Parathyroidectomy improved ectopic calcification in renal failure patients, but did not prevent peripheral arterial calcification. Bone histology showed persistent woven bone and occasional osteomalacia post-surgery.

    Area of Science:

    • Nephrology
    • Endocrinology
    • Pathology

    Background:

    • Secondary hyperparathyroidism is common in chronic renal failure.
    • Ectopic calcification is a significant complication in these patients.
    • The impact of parathyroidectomy on ectopic calcification requires further investigation.

    Purpose of the Study:

    • To determine if parathyroidectomy alters the natural history of ectopic calcification in patients with chronic renal failure and secondary hyperparathyroidism.

    Main Methods:

    • Analysis of 62 patients with secondary hyperparathyroidism undergoing parathyroidectomy.
    • Collection of biochemical and radiological data before and after surgery.
    • Examination of transiliac bone biopsies pre- and post-parathyroidectomy.

    Main Results:

    • Parathyroidectomy controlled hyperparathyroidism in most patients, though relapse occurred in 11%.
    • Non-visceral soft tissue calcification decreased in 60% of patients.
    • Peripheral arterial calcification developed or progressed in 56% despite improvements in bone disease.
    • Osteomalacia was observed in two patients with excess bone aluminum.

    Conclusions:

    • Parathyroidectomy can improve soft tissue calcification and bone disease in renal failure patients.
    • It does not prevent the progression of peripheral arterial calcification.
    • Bone histology reveals persistent changes, including woven bone, for extended periods post-surgery.
