[Intravenous subtraction angiography in kidney transplant patients]

Conventional arteriography in patients with kidney transplants and severe hypertension is performed principally to determine the presence of a renal artery stenosis. In patients with renal failure its use enables detection of any arterial lesions. Technological advantages provided by computerized angiography within the field of medical imaging should permit earlier diagnosis of arterial lesions, with a reduced risk and at a lower cost using a simple intravenous injection of the iodized contrast medium.
