parathyroidectomy is the surgical elimination of 1 or more parathyroid glands. this technique is used to dispose of number one tumors or hyperplasia of the glands, in particular when they produce immoderate parathyroid hormone (hyperparathyroidism). the location of the glands is typically in the back of the thyroid, but there is a lot of variation. typically, the location of an enlarged gland has been confirmed by means of a sestamibi scan or on ultrasound.
the main indication for parathyroidectomy is primary hyperparathyroidism, in which one or extra of the parathyroid glands produce excessive parathyroid hormone. no longer all instances of primary hyperparathyroidism require surgical treatment, but it's far advocated if the circumstance reasons full-size signs or if it affects the kidneys (nephrocalcinosis) or bone health (osteoporosis), and additionally in humans under 50 even if they do no longer have signs. it isn't usually possible to expect if a parathyroid tumor is malignant (i.e. capable of invading other tissues or spreading someplace else). any suspicion of parathyroid carcinoma is therefore additionally an indication for surgical treatment.
parathyroidectomy may also be required in secondary hyperparathyroidism. this situation arises specially in human beings with severe persistent kidney sickness in which the parathyroid glands are overactive to compensate for the low calcium and nutrition d ranges frequently found in ckd. in lots of instances, the parathyroid hormone production improves while these abnormalities are treated with medicine.
a small percentage, but, have consistently raised hormone ranges six months after remedy has started, idea to be autonomous production of hormone with the aid of the glands and loss of feedback mechanisms. in this situation surgical parathyroidectomy can be required, specifically if calcium and phosphate levels continue to be elevated, there's calcium deposition at the blood vessels (calciphylaxis in excessive instances) or there's worsening bone disorder. in human beings on dialysis, parathyroidectomy can improve their survival. it does seem that the manner can be underused.
at the same time as slight hypocalcemia is not unusual after parathyroidectomy, some human beings revel in chronic prolonged low calcium degrees as osteoclast cells inside the bones get rid of huge amounts of calcium from the bloodstream whilst the continuous presence of pth is all at once eliminated. this is known as hungry bone syndrome. extended calcium supplementation can be required. hungry bone syndrome is particularly commonplace in folks who are on lengthy-term normal dialysis.
