RESUMO
Aim: To evaluate the incidence of complications, including fatal outcomes, ischemic strokes, and transient ischemic attacks, associated with carotid endarterectomy (CEA) in patients categorized as low-, medium-, and high-risk based on their CarotidSCORE (carotidscore.ru). Material and Methods: This prospective, multicenter study was conducted from January 1, 2022, to December 20, 2022, and enrolled 5,496 patients with stenosis of the internal carotid artery (ICA), who were categorized into four groups according to their risk level. Group 1 (n=1,759) included patients at low risk; Group 2 (n=2,483) included those at medium risk; Group 3 (n=429) included those at high risk, who underwent carotid angioplasty with stenting (CAS) due to the high risk of complications associated with carotid endarterectomy (CEA); and Group 4 (n=825) did not use CarotidSCORE (carotidscore.ru). Patients in Groups 1, 2, and 4 underwent CEA. Results: During the postoperative hospital stay, the highest number of complications, including fatal outcomes (p=0.0007), ischemic strokes (p<0.0001), and the combined endpoints (p<0.0001) were observed in Group 4. No complications were reported in Group 1. Conclusion: The use of CarotidSCORE (carotidscore.ru) allows for the identification of high-risk patients, enabling clinicians to opt for CAS instead of CEA and reduce the incidence of complications.
RESUMO
This review of the literature discusses the solution of unresolved issues related to carotid endarterectomy in Russia: (1) A program has been created for choosing the tactics of revascularization of patients with simultaneous atherosclerotic lesions of the coronary and carotid arteries; (2) Using the methods of computer modeling, studying the genetics and morphology of restenosis, it was found that the classic carotid endarterectomy with plasty of the reconstruction zone with a patch is an unsafe type of revascularization; (3) An eversion carotid endarterectomy with transposition of the internal carotid artery over the hypoglossal nerve has been developed, which makes it possible to prevent damage to the latter during repeated carotid endarterectomy for restenosis; (4) It has been established that carotid endarterectomy is associated with a high risk of complications in patients over 75 years of age; (5) It has been proven that emergency carotid endarterectomy in the first hours after the development of a stroke is not safe because. combined with the maximum number of all non-favorable cardiovascular events; (6) 3 new types of carotid endarterectomy with carotid glomus preservation have been developed.
