ABSTRACT:
Purpose: The aim of the study was to evaluate the risk factors for CAS with cerebral protection and the incidence of complication in patients with severe carotid stenosis. Materials and Methods: Overall, 95 consecutive patients with an average age of 64.67 years (28 - 83) (16 women (17%) and 79 men (83%)) were enrolled in the prospective monocentric study. Indication for CAS was symptomatic carotid stenosis ≥70% (n = 60 (63.16%)) or asymptomatic stenosis ≥80% (n = 35 (36.84%)) according to the NASCET criteria on DSA, which were not suitable for surgery. Results: From the selected risk factors, the most frequently found were arterial hypertension in 87 patients (91.6%), ischemic heart disease in 70 (73.7%), hyperlipidemia in 61 (64.2%), history of stroke in 43 (45.3%), diabetes mellitus in 35 (36.8%), smoking in 13 (13.7%), and age more than 75 years in 9 (9.5%). Significantly more frequent complications in elderly patients (more than the age of 75 years) were experienced: TIA (p = 0.049), early death (p = 0.049), restenosis (p = 0.04), and overall mortality (p = 0.04). Conclusion: Among the studied risk factors, only patients more than the age of 75 years were affected by the incidence of serious complications.
