Mazzaccaro D, et al. - Researchers examined 473 patients older than 80 years undergoing either carotid endarterectomy (CEA) or carotid artery stenting (CAS) for carotid stenosis, to determine preoperative risk factors affecting their long-term survival and the occurrence of stroke. Patients older than 80 years showed low 30-day mortality and any-stroke rates on undergoing CEA or CAS. In the long term, significantly better survival was observed after CAS. Deaths after CEA and CAS were, however, not related to the procedure in the majority. The occurrence of any stroke was not significantly different in the long term. A significant effect of the presence of preoperative AF as well as being classified as American Society of Anesthesiologists class 3 at evaluation of the preoperative anesthesiology risk on long-term survival after CAS was observed. Long-term risk of stroke after both CAS and CEA was also significantly affected by the presence of preoperative AF.
