Introduction: We compared the incidence of intraprocedural bradycardia and hypotension during carotid artery stenting in patients with primary carotid artery stenosis and those with prior ipsilateral carotid endarterectomy. Methods: A total of 213 carotid stenting procedures were performed in our institution in a 4-year period. The mean degree of stenosis was 78% (range 60-99%). Of these 213 procedures, 43 were performed for carotid restenosis, 9 after stenting and 34 after endarterectomy, and 170 for primary stenosis. Atropine was selectively administrated if patients suffered bradycardia (a decrease in heart rate to < 50% or an absolute heart rate of < 40 bpm) or hypotension (systolic blood pressure < 90 mmHg). We compared the group of patients with primary stenosis (n=170) and the group of patients with restenosis after carotid endarterectomy (n=34) in relation to intraprocedural hypotension or bradycardia/need for atropine administration. Results: Hypotension occurred in 49 patients with primary stenosis and 2 patients with restenosis. The difference was statistically significant. Atropine was administered for bradycardia to 58 patients with primary stenosis and 3 patients with restenosis. The difference was statistically significant. Conclusion: Intraprocedural bradycardia and hypotension occur more frequently in patients with primary carotid artery stenosis.
