Abstract
Background and Purpose: Management of carotid stenosis remains controversial despite several trials evaluating carotid endarterectomy (CEA) and carotid angioplasty/stenting (CAS). We compared attitudes in the management of carotid stenosis between selected experts within Europe and North America. Methods: A 3-phase Delphi survey was e-mailed to select stroke experts from Europe (n = 390) and North America (n = 289). Those completing the initial survey were shown all responses after each survey round. Consensus was defined as ≥ 80% agreement. Results: For phases 1, 2, and 3, response rates were 32%, 62%, and 73%, respectively. Overall, 100 (15%) of 679 participated in all 3 phases, 19% Europeans versus 9% North Americans (P =.0007). The European group reached consensus in 6 of 15 statements; The North American group reached consensus in 4 of 15. Ninety percentage of Europeans versus 70% of North Americans (P =.017) stated CEA is superior to CAS for symptomatic carotid stenosis. This difference was not significant in the final model (adjusted odds ratio: 3.72 [95% confidence interval: 0.95- 14.5]). Sixty-nine percentage of North Americans agreed there is a stronger indication for CAS over CEA in patients younger than 65 years for symptomatic carotid stenosis, whereas 55% of Europeans (P =.023) disagreed. For asymptomatic carotid stenosis, when asked how likely they would recommend CAS, 62% North Americans said “sometimes” versus 60% of Europeans said “never” (P =.06). Conclusion: The majority of North American and European respondents did not consider the 2 procedures equivalent and seemed to indicate that CEA was preferred for the management of carotid stenosis. These findings need to be further explored to help establish evidence-based guidelines.
