Abstract |
Objective The goal of this study was to compare restenosis in patients treated with carotid endarterectomy (CEA) and carotid angioplasty
and stenting (CAS) in the elderly.
Methods The study comprised 19 patients who were over 65 years and underwent 19 CEA procedures between June 2004 and July 2011, and 35 patients who over 65 years and underwent 39 CAS procedures between January 2007 and December 2011. All patients had atherosclerotic stenosis of ≥60% of the carotid artery, as determined by the North American Symptomatic Carotid Endarterectomy Trial (NASCET) method.
Results In the CEA group, 17 (89%) patients were men and 2 (11%) were women. The mean ages in the CEA group was 74.5±4.1 years. In the CAS group, 24 (69%) patients were men and 11 (31%) were women, with a mean age of 71.5±3.8 years. The mean pre-treatment stenosis in the CEA group was 70.6±7.6%, and in the CAS group was 76.4±10.4%. Whereas none of CEA patients developed severe restenosis (≥70% or occlusion), 3 (8.5%) patients of the CAS group developed severe restenosis (mean stenosis, 83.3±8.5%).
Conclusion Our study suggests that the rate of restenosis after CEA was lower than after CAS. CEA is superior to CAS with respect to restenosis rates in the elderly. |
