Abstract:

Aim: was to identify risk factors of early adverse cerebral events after carotid artery stenting anc endarterectomy

Materials and methods: 908 patients who underwent isolated carotid stenting (N = 522) and carotid endarterectomy (N = 386) were included in this retrospective analysis. Patients with simultaneous cardiac surgery and patients with symptomic stenosis of CA were excluded from research. The primary end point was ipsilateral perioperative ischemic stroke, proved by neurologist and CT/MRI data. To identify predictors, multivariate regression was used, with factors that could influence endovascular and surgical methods of treatment.

Results: patients from two groups were similar in main clinical and demographic characteristics. There were no deaths and cerebral hemorrhagic complications. The stroke rate in the endovascular and surgical groups was 1.7% and 1.04% respectively (p = 0.5). The total rate of strokes and transitory ischemic attack (TIA) using two methods was 1.4%. The TIA rate was higher in the endovascular group without statistically difference (1.3% vs. 0.3%, p = 0.1). The regression analysis showed that predictor of the adverse cerebral events was the degree of carotid artery stenosis in endovascular group (OR 1.318, 95% CI: 1.131-1.535, p <0.001). There were no any predictive factors of TIA or stroke in the surgical group.

Conclusions: the independent predictor of early TIA and stroke in endovascular group, unlike endarterectomy, was the degree of carotid stenosis.
