[Carotid endarterectomy without arteriography: only dedicated to urgent procedures?]

Duplex examination is presently established as a safe non-invasive and accurate method of evaluating patients with extracranial cerebrovascular disease which usually provides complete information about the extent of carotid artery narrowing Arteriography, in this indication, is an invasive procedure with a total complication rate of 3-4% with 1% of permanent stroke. If it is currently accepted that in emergency conditions (ictus ingravescens, pre-occlusive plaque) or if iodinated contrast media are contraindicated, thrombendarteriectomy can be performed without arteriography it could be extended to most cases. The authors stress the criteria to increase the number of those patients, summarize the pre-requisites to achieve this goal, and comment on the future alternative position of MRA.
