Carotid artery angioplasty is a preventive measure to decrease a risk of cerebral ischemia due to stenosis of the internal carotid artery bifurcation. To achieve this purpose, it is crucial that the procedure has a minimal risk of complications and its effect is long-lasting. The purpose of our study was to verify safety of carotid angioplasty and its long-term effect in clinical practice.

Material and method:
The study included 450 patients with 442 carotid artery stents and 8 plain carotid angioplasties since 1997. Complications occurring during the first three days after the procedure (periprocedural complications) and during long-term clinical and ultrasonographical follow-up (median 33 months) were recorded.

The risk associated with carotid angioplasty was low: in hospital mortality due to intracerebral hemorrhage was 0.5%, minor stroke occurred in 1.0%, transient ischemic attack in 2.4%. > 70% restenosis was found in 3.6% of the 76% of all patients who had long-term follow-up. Asymptomatic restenoses were 81%.

Our results confirmed that carotid angioplasty is a safe method with beneficial long-term effect if it is done for appropriate indication and performed by a skilled intervention radiologist.

Key words:
carotid stenting – periprocedural complication – long-term follow-up – restenosis
