Abstract 2222: Acute Results and 30-Day Follow-up of Carotid Stenting in Patients with Carotid Stenoses: A Comparison Between Open and Closed Cell Stent Design
Background: It has been postulated that in symptomatic patients carotid stents with a closed cell design prevent subacute and even late embolic events better than stents with an open cell design.
Patients and Methods: 845 consecutive carotid stenting procedures were performed in 288 symptomatic stenoses (180 open cell and 108 closed cell stents) and 557 asymptomatic stenoses (354 open and 203 closed cell stents). Stents were used according to availability and operator decision, not intentionally driven by symptomatic status or lesion morphology. In both groups (asymptomatic and symptomtic), there were no statistically significant differences in baseline characteristics, lesion morphology and the use of embolic protection devices between the lesions treated with open and those treated with closed cell stent.
Results: There was no significant difference between open and closed cell stents but a trend towards worse outcome with closed cell stents in symptomatic patients.
Conclusion: The acute and subacute results of carotid stenting were not significantly different between open and closed cell stents. There was a trend towards better results with open cell stents in symptomatic patients.
