Abstract
Background. Neck reexploration for primary hyperparathyroidism has a lower success rate and greater
morbidity than initial exploration because of scarring and distortion of tissue planes
and the possibility of a parathyroid neoplasm located in an ectopic or unusual position.
Although the use of standard noninvasive imaging studies for reoperative parathyroid
surgical procedure is well accepted, the use of invasive studies to localize parathyroid
neoplasms, particularly percutaneous aspiration of potential lesions, is controversial.
In this report we analyze the results and morbidity in patients undergoing fine-needle
aspiration before neck reexploration.
Methods. From 1982 to 1993, 255 patients underwent reexploration for persistent or recurrent
hyperparathyroidism at the National Institutes of Health. Of these 255 patients 42
underwent 44 preoperative fine-needle aspirations by ultrasonography or computed tomography
guidance in an attempt to localize a parathyroid neoplasm. The aspirated contents
were then analyzed for parathyroid hormone content.
Results. Of the 44 aspirations 26 (59%) were true positives with no false positives. Of 18
negative fine-needle aspirations, 11 (25%) were false negatives, and seven (16%) were
true negatives. The specificity and sensitivity of percutaneous fine-needle aspiration
were 100% and 70%, respectively.
Conclusions. Percutaneous fine-needle aspiration for parathyroid hormone is a safe, well-tolerated
technique that is highly specific and allows a directed surgical resection avoiding
further invasive workup when the aspirate is positive.
