Background and Purpose-Protection devices are increasingly used in carotid artery stenting. However, no randomized trial has been conducted to evaluate the efficacy of such devices, and arguments have also been formulated against their routine use. We set out to investigate the complication rates associated with carotid artery stenting performed without protection devices. Applicability of covered stents in the carotid system was also evaluated. Methods-Between

Covered stents provide efficient peri- and post-procedural protection against neurological complications due to embolisation from high-risk plaques during carotid artery stenting. Restenosis of covered stents appears to be infrequent during long-term follow-up.
