Parathyroid adenomas studied by digital subtraction angiography

|November 1, 1984
Summary
Digital subtraction angiography (DSA) may help locate parathyroid adenomas. However, this imaging technique showed low sensitivity, limiting its use for screening patients with high calcium and parathormone levels.
Area of Science:
- Endocrinology
- Radiology
- Surgical Oncology
Background:
- Elevated serum calcium and parathormone levels often indicate parathyroid adenomas.
- Accurate preoperative localization of parathyroid adenomas is crucial for successful surgical intervention.
Purpose of the Study:
- To prospectively evaluate the utility of intravenous digital subtraction angiography (DSA) in identifying parathyroid adenomas.
Main Methods:
- Eighteen patients with hypercalcemia and hyperparathyroidism underwent intravenous DSA of the neck and mediastinum.
- DSA was performed in multiple projections and considered positive for adenoma if abnormal vascularity was detected.
Main Results:
- Fourteen patients were diagnosed with parathyroid adenomas upon surgical confirmation.
- Preoperative DSA correctly identified adenomas in only five of these 14 patients (35.7% sensitivity).
- Three of four medically managed patients had negative DSA, while one had a positive DSA finding.
Conclusions:
- Intravenous DSA may offer some guidance for neck exploration in suspected parathyroid adenomas.
- The low sensitivity of DSA suggests it is not a reliable primary screening tool for parathyroid adenoma detection.
