Preoperative Cardiac Evaluation with Dipyridamole Thallium-201 Screening reduced Perioperative Mortality and Cardiovascular Complications in Secondary Hyperparathyroidism Patients undergoing Parathyroidectomy

Forty-four of the 55 patients had comorbidities such as hypertension, diabetes, and so on. In all the cases, PTX was successfully performed and the serum levels of parathyroid hormone and calcium lowered. Neuropsychiatric symptoms also improved in 14 patients after PTX. Except two cases, no severe complication occurred after PTX: one developed aspiration pneumonitis and one needed hemodialysis for acute exacerbation in chronic kidney disease.
