Conclusions- The increased procedural stroke or death risk associated with CAS compared with CEA was caused by an excess of events occurring on the day of procedure.
Propensity-matched logistic regression revealed that symptomatic males vs females had lower odds of stroke after CEA (odds ratio [OR] 0.81; 95% CI 0.72 to 0.91) and CAS (OR 0.72; 95% CI 0.57 to 0.90).
For symptomatic and asymptomatic patient with high or intermediate risk of CEA complications, CAS with the use of EPDs has a very low rate of in-hospital stroke and death There is no statistically significant difference in ipsilateral stroke/TIA and any stroke/TIA between the different device platforms Further efforts to assess differences between EPD devices would likely need to involve a surrogate endpoint due to the very low rates of clinical events.
