Primary hyperparathyroidism in dogs and cats.

The most common cause of primary hyperparathyroidism in dogs and cats is a solitary adenoma involving an extracapsular parathyroid gland. The prognosis is excellent if the affected parathyroid gland is removed. Nonsurgical methods are discussed, although there are no current data to support any benefit over conventional surgery. The common postoperative complication to consider is hypocalcemia. Hypocalcemia can be successfully managed in these animals if it is anticipated and treated promptly.
