[Thyroid phlebography and selective venous sampling for parathormone estimations in primary hyperparathyroidism (author's transl)].

Selective venous sampling for parathormone estimations has become an important method in the diagnosis of primary hyperparathyroidism and, together with thyroid phlebography, is an accurate means for localising hormone active parathyroid tissue. Thirty-three patients were examined by this technique and in 25 of these an exploration was carried out subsequently. Twenty-one had primary hyperparathyroidism. In one case hormone analysis lead to a false positive finding. In 18 of these 21 patients, the hormone-active parathyroid tissue was correctly localised. Phlebography showed evidence of an adenoma in five patients, but is of most use for localising the source of the hormone.
