Results of intravenous digital subtraction angiography (IVDSA) as a screening method for renovascular hypertension.
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.
