AIMS: Distal embolisation during carotid artery stenting (CAS) is the main cause of cerebral complications; thus, the amount of embolisation occurring during CAS can be considered as a surrogate endpoint of cerebral complications. Our aim was to find patient characteristics which are associated with a higher risk of embolisation during CAS. METHODS AND RESULTS: From January to December 2010 all consecutive patients undergoing CAS with embolic protection at three medium- to high-volume Italian centres were prospectively enrolled in this multicentre study. After CAS, the embolic debris was classified by visual inspection into two groups: "scarce" (no debris or hardly visible debris), and "relevant" (visible embolic debris) embolisation. Two hundred and thirty-six consecutive patients (79% males, 32.7% symptomatic) were enrolled. Open cell stents were used in 52.7% of the patients, distal filters were employed in 85.5% and proximal protection in 14.5%. Procedural success was achieved in 100% of procedures. Relevant embolisation was observed in 16.1% of patients, including those who suffered all the periprocedural complications (4.2%). At multivariate statistical analysis, high circulating LDL cholesterol and C-reactive protein levels were the only factors associated with relevant embolisation. CONCLUSIONS: In this study, high circulating LDL cholesterol and C-reactive protein levels were associated with relevant embolisation after CAS, opening up the hypothesis that therapy with statins before elective CAS may reduce plaque embolisation and improve outcome.

Abstract

AIMS: Distal embolisation during carotid artery stenting (CAS) is the main cause of cerebral complications; thus, the amount of embolisation occurring during CAS can be considered as a surrogate endpoint of cerebral complications. Our aim was to find patient characteristics which are associated with a higher risk of embolisation during CAS. METHODS AND RESULTS: From January to December 2010 all consecutive patients undergoing CAS with embolic protection at three medium- to high-volume Italian centres were prospectively enrolled in this multicentre study. After CAS, the embolic debris was classified by visual inspection into two groups: "scarce" (no debris or hardly visible debris), and "relevant" (visible embolic debris) embolisation. Two hundred and thirty-six consecutive patients (79% males, 32.7% symptomatic) were enrolled. Open cell stents were used in 52.7% of the patients, distal filters were employed in 85.5% and proximal protection in 14.5%. Procedural success was achieved in 100% of procedures. Relevant embolisation was observed in 16.1% of patients, including those who suffered all the periprocedural complications (4.2%). At multivariate statistical analysis, high circulating LDL cholesterol and C-reactive protein levels were the only factors associated with relevant embolisation. CONCLUSIONS: In this study, high circulating LDL cholesterol and C-reactive protein levels were associated with relevant embolisation after CAS, opening up the hypothesis that therapy with statins before elective CAS may reduce plaque embolisation and improve outcome. (EudraCT number: 016737-95).
