RESUMO
Since January 1982 we have combined urography in hypertensive patients with intravenous angiography of the renal arteries. In more than 80% of 163 patients the examination was of good diagnostic quality and both renal arteries were well visualised. IVDSA has a lower morbidity and cost than conventional angiography. It is more accurate than urography and therefore offers better screening of a selected group of hypertensive patients.

We describe two cases of hypervascular, endocrine tumors demonstrated by intravenous digital subtraction angiography (IV DSA), the first an insulinoma in the head of the pancreas and the second a pheochromocytoma of the left-side adrenal gland. The limitations of IV DSA to reveal these tumors is considered as well as the possible value of the modality as a screening procedure for endocrine neoplasms.
