Conditions

Parathyroid adenoma, near-infrared fluorescence imaging, methylene blue

Interventions

Standard parathyroid adenoma resectino will be performed. After opening the neck region, methylene blue will be injected intravenously to identify the parathyroid adenoma using NIR fluorenscence.

Eligibility

Inclusion criteria

Inclusion criteria: 1. Patients diagnosed with primary hyperparathyroidism; 2. Age between 18 and 80.

Exclusion criteria

Exclusion criteria: 1. Allergy for Methylene blue; 2. Patients using SSRIs, SNRIs of TCAs; 3. Pregnancy; 4. Severe renal impairment; 5. Patients with a G6PD deficiency.

Design outcomes
