Abstract
Introduction. Although surgical endarterectomy remains the treatment of choice for carotid artery stenosis, carotid artery stenting (CAS) with use of proximal protection systems (PPS) plays an important role as alternative treatment modality, especially in high risk patients. This study was aimed at the assessment of safety of CAS with use of the PPS and also at identification of risk factors associated with this procedure.
Material and methods. This was a post hoc analysis, with 30-day follow-up. We analysed results of treatment of 94 patients who underwent 97 CAS with PPS, 47 such procedures in asymptomatic, and 50 in symptomatic individuals.
Results. There were 0 strokes during 30-day follow-up. Transient ischaemic attacks occurred in 2 patients (2%) in symptomatic group. Risk factors of these adverse events comprised: tortuosity of the managed artery, chronic obstructive pulmonary disease, long lesion of the internal carotid artery and history of myocardial infarction.
Conclusions. CAS with the use of PPS seems to be a relatively very safe procedure in high risk patients.
