Abstract
One hundred fiftyfive patients underwent CAS between February 2010 and December 2012 Ninetyone open and 84 closedcell stents were used in this nonrandomized retrospective study Periprocedural complications were defined as the ones happened during the procedure or within 30 days afterwards Starting from the 6th month after the procedure instent restenosis was detected with multidetector computed tomography angiography and classified into four groups from focal restenosis to occlusionEleven complications were encountered in the periprocedural period four on the open and seven on the closedcell group Total complication rate was 63 11/175 No significant difference was detected in terms of periprocedural complications between two groups p = 0643 There was statistically significant difference between stent design groups in regard to radiological findings p = 0002 Sixteen of opencell stents and three of closedcell stents had focal restenosis One closedcell stent had diffuse proliferative restenosis and one opencell stent had total occlusionInstent restenosis was more common in opencell stent group which have larger free cell area than closedcell stents Although our radiologic findings promote us to use closedcell design if ‘possible’ no difference was detected in terms of clinical outcomes
