The frequency, risk factors and long term consequences of reflexive postprocedural hypotension (PH) following carotid artery stenting (CAS) are not well known. Prospective analysis of 30 patients with 6-month follow-up undergoing CAS with an emboli-protection device was performed. A validated 24-hour ABPM was taken 24 hours before and after CAS. PH was defined as systolic blood pressure (SBP) <90 mm Hg, or decrease in mean arterial BP (MAP) of ≥20% or systolic BP (SBP) of ≥30 mm Hg of baseline BP reading. Neurological assessments were performed 24 hours after CAS and at 6 month follow-up visit. Median age was 69 years, 70% were male, 86% of patients had symptomatic carotid stenosis. Twenty patients (67%) experienced PH, 43% had transient bradycardia, 30% had both PH and bradycardia. The cumulated postprocedural mean SBP and DBP decreased from baseline 128/67 mm Hg to 108/54 mm Hg (p <0.01), mean day (69/min) and night HR (58/min) decreased to respectively 58/min and 49/min (p <0.01). We found no association of PH with age, ischemic heart disease, bifurcation involvement, balloon size, inflation pressure, longer lesion length. Patients with PH significantly (p <0.05) less often were treated with Ca-antagonist (25% vs 70%), more often had ipsilateral ulcerated plaque (85% vs 50%) and had hemodynamically significant stenosis of contralateral ICA (60% vs 30%). During 6 month follow-up only 1 case of neurological deterioration was noticed. PH was a common phenomenon after CAS, however it did not result in neurological complications. Patients at risk can be possibly identified through clinical and angiographic variables.
