The role of venous digital subtraction angiography of the carotid bifurcation in the evaluation of patients with reversible ischemic attacks or stroke.

The development of Computed Tomography and Magnetic Resonance has reduced the diagnostic role of Digital Subtraction Angiography (DSA) in the neuroradiological evaluation of intracranial tumors. DSA is currently an important pre-surgical examination, able to offer important information regarding the type and the entity of neoplastic vascularization. Moreover the development of endo-vascular interventional practices (pre-surgical embolization of meningiomas and endo-arterious chemotherapy of gliomas) has widened the applications of angiography.

Demonstrated in this report is an example of arteriovenous shunting and early venous filling in an area of cerebral infarction recorded on digital subtraction angiography. This angiographic appearance is largely of historical interest given the current use of sectional imaging (CT and MR) and altered role of angiography in the imaging of stroke, but should nevertheless still be considered amongst the differential causes of cerebral arteriovenous shunting.

Abstract Advances in digital subtraction angiography (DSA) have allowed the evaluation of a number of pathological conditions involving the extra-and intracranial vasculature. In addition to its role in diagnosis. DSA has been used for the postoperative assessment of endarterectomy, aneurysm clipping, and vascular bypass and for the follow-up of arteriovenous fistulas or malformations. This paper describes the theory and anticipated improvements in the digital processing of radiological information and presents our initial assessment of its clinical utility.
