NASCET, ACAS trials remain to be gold standards for
reducing the risk of a subsequent cerebro-vascular accident. Despite several
large studies the literature remains unclear about the absolute benefit of one
procedure over the other. The recent data from CREST has showed increased risk
of CVA among the patients undergoing CAS (4.1% vs 2.3%) and decreased risk of MI in CAS compared with CEA ( 1.1% vs2.3%). In
this study Brewster et al have studied 495
procedures performed at one institute where 14 physicians participated
in 3 year study period.
