ABSTRACT
INTRODUCTION The widespread availability of noninvasive angiographic techniques, notably computed tomography (CT) and magnetic resonance (MR) angiography, has had a dramatic impact on the practice of routine peripheral angiography of the upper and lower extremities (1-3). Most invasive angiographic studies are now performed to confirm the findings on noninvasive studies for the purpose of performing vascular intervention or to image small diameter extremity vessels for which the resolution of CT or MR angiography is insufficient. The result is a more targeted and individualized approach to angiography that answers a clinical question or helps direct a therapy. This chapter will outline the angiographic anatomy of the arterial supply of the upper and lower extremities, and provide a practical approach to angiography of these territories.
