Purpose Parathyroid venous sampling (PAVS) is usually
reserved for patients with persistent or recurrent hyper-
parathyroidism after parathyroidectomy with inconclusive
noninvasive imaging studies. A retrospective study was
performed to evaluate the diagnostic efficacy of super-se-
lective PAVS (SSVS) in patients needing revision neck
surgery with inconclusive imaging.
Materials and Methods Patients undergoing PAVS
between 2005 and 2016 due to persistent or recurrent
hyperparathyroidism following surgery were reviewed.
PAVS was performed in all patients using super-selective
technique. Single-value measurements within central neck
veins performed as part of super-selective PAVS were used
to simulate selective venous sampling (SVS) and allow for
comparison to data, which might be obtained in a non-
super-selective approach.
Results 32 patients (mean age 51 ± 15 years; 8 men and
24 women) met inclusion and exclusion criteria. The sen-
sitivity and positive predictive value (PPV) of SSVS for
localizing the source of elevated PTH to a limited area in
