[Predictors of long-term complications after carotid endarterectomy].

AIM
To analyze the predictors of complications within 3 years after carotid endarterectomy (CEE).


MATERIAL AND METHODS
The study included 1035 patients after CEE for the period 2011-2016. Long-term follow-up period was 42.4±18.6 months (≈ 3.5 years). The endpoints were such unfavorable cardiovascular events as death, myocardial infarction, stroke/transient ischemic attack, redo revascularization. Statistical analysis was carried out by using of Statistica for Windows 8.0 software package (StatSoft Inc., USA). Stepwise logistic regression was applied to identify risk factors of adverse outcomes and death in long-term postoperative period.


RESULTS
Comprehensive analysis of numerous factors (anamnestic, instrumental-diagnostic, surgical) allowed us to identify predictors of long-term unfavorable outcomes in patients with occlusive-stenotic lesions of carotid arteries. Risk factors of long-term complications were SYNTAX score ≥33 (high risk), unstable plaque in the contralateral ICA, occlusion of contralateral ICA, LVEF <39%, ICA cross-clamping >40 min, previous CABG.


CONCLUSION
These data are extremely important and can be used to create prognostic models. The last ones are necessary to determine optimal treatment strategy in patients with occlusive-stenotic lesions of supra-aortic vessels.
