What is the risk of stroke/death associated with CEA and CAS in patients who underwent the procedure within 1 week of a stroke or TIA?
The Carotid Stenosis Trialists Collaboration evaluated 4138 patients randomly assigned to CEA or CAS. In patients who received the procedure within 1 week of the last symptomatic event, the stroke/death rate was 8.3% with CAS versus 1.3% with CEA (RR, 6.7; P=0.002).
