Abstract
Aim. Analysis of hospital and long-term results of carotid endarterectomy (CEA) in different periods of acute cerebrovascular event (ACVE). Materials and Methods. The given study was retrospective and was conducted using the method of patients sampling. In the period from 2010 to 2019, 1113 patients with ACVE in history who were later conducted CEA, were selected. Depending on the time interval between the last ACVE and CAE, all the patients were divided into 4 groups: the 1st group – in the acutest period of ACVE (1-3 days) (n=24; 2.2%); the 2nd group – in the acute period of ACVE (up to 28 days) (n=493; 44.3%); the 3rd group – in the early rehabilitation period of ACVE (up to 6 months) (n=481; 43.2%); the 4th group – in the late rehabilitation period of ACVE (up to 2 years) (n=115; 10.3%). The long-term period was 34.8±12.5 months. Results. In the hospitalization period of observation the following complications were found: lethal outcome ((group 1 – 0%; group 2 – 0.4% (n=2); group 3 – 0.2% (n=1); group 4 – 0%; р=0.16)); myocardial infarction ((group 1 – 0%; group 2 – 0.4% (n=2); group 3 – 0%; group 4 – 0.9% (n=1); р=0.35)); ACVE/transient ischemic attack (TIA), ((group 1 – 4.2% (n=1); group 2 – 0.4% (n=2); group 3 – 0.2% (n=1); group 4 – 0%; р1-2=0.01; р1-3=0.009; р1-4=0.01)). By the end of hospitalization period the composite endpoint consisting of lethal outcome + myocardial infarction + ACVE/TIA made in group 1 – 4.2% (n=1), in group 2 – 1.2% (n=6), in group 3 – 0.4% (n=2), in group 4 – 2.6% (n=3), р=0.08. Complications of the long-term follow-up period were: lethal outcome from all causes ((group 1 – 25% (n=6); group 2 – 5.5% (n=27); group 3 – 7.3% (n=35); group 4 – 14% (n=16); р1-2=0.002; р1-3=0.008; р2-4=0.012)); lethal outcome from cardiovascular causes ((group 1 – 4.2% (n=1); group 2 – 3.6% (n=18); group 3 – 4.8% (n=23); group 4 – 5.2% (n=6); р=0.79)), myocardial infarction ((group 1 – 12.5% (n=3); group 2 – 3.6% (n=18); group 3 – 5.4% (n=26); group 4 – 6.1% (n=7); р=0.15)), ACVE/TIA ((group 1 – 16.6% (n=4); group 2 – 6.3% (n=31); group 3 – 6% (n=29); group 4 – 11.3% (n=13); р=0.05)); composite endpoint including lethal outcome + myocardial infarction + ACVE/TIA ((group 1 – 54.2% (n=13); group 2 – 15.4% (n=76); group 3 – 18.7% (n=90); group 4 – 31.3% (n=36); р1-2=0.0001; р1-3=0.0001; р1-4=0.005; р2-4=0.0006; р3-4=0.012)). Conclusion. Application of CEA demonstrated effectiveness and safety in the acute and early rehabilitation period of ACVE.
