Postoperative hypoparathyroidism after thyroid surgery

摘要: Postoperative hypocalcaemia, secondary to hypoparathyroidism, is the most common complication observed in patients who undergo bilateral thyroid resection. Although hypocalcaemia self-limiting and does not require treatment, symptomatic of particular concern. The cause postoperative hypoparathyroidism has commonly been attributed devascularization injury parathyroid glands or their accidental Depending on extent gland devascularization, may be transient, resolving a few months, it permanent, requiring lifelong oral calcium vitamin D supplementation. degree functional reduction parenchyma seems directly related severity earlier onset hypocalcaemic symptoms. Early monitoring serum concentration demonstrated useful identification whom will develop. However, even though slope correlate with development hypocalcemia, these results are often until 12 24 hours after operation. This delay can postpone therapy prolong hospitalization. On other hand, many studies have usefulness perioperative parathormone measurement at risk developing hypocalcaemia. These that absolute levels percentage decline PTH measured minutes thyroidectomy accurately predict identify supplementation those safely discharged without any treatment. Moreover, combining could result an accurate prediction
