title: Localization of parathyroid adenomas in patients who have undergone surgery. Part II. Invasive procedures.
abstract: The authors studied intraarterial digital subtraction angiography (DSA), conventional selective angiography, parathyroid venous sampling (PVS), and intraoperative ultrasound (US) as localization procedures for parathyroid adenomas in 53 patients with proved parathyroid adenomas and previous unsuccessful parathyroid surgery. PVS had the highest overall sensitivity as a single study (80%), followed by intraoperative US (78%), angiography (60%), and DSA (49%). Invasive procedures permitted successful localization of adenomas in 41 of 43 patients studied (95%). False-positive studies were uncommon. The optimum sequence of invasive localization procedures is determined by clinical factors and not by the sensitivity of individual tests. The authors recommend DSA be performed first, followed by angiography, PVS, and intraoperative US, in that order.
