Percutaneous coronary intervention and carotidal endarterectomy: hospital and long-term outcomes of hybrid interventions and predictors of complications

Abstract

Goal. Analysis of hospital and long-term results with the identification of predictors of complications after combined interventions on the coronary and carotid arteries in the volume of percutaneous coronary intervention + carotid endarterectomy (PCI + CEE). Materials and methods. From 2010 to 2016, 64 patients underwent hybrid revascularization of the brain and myocardium in the volume of PCI + CEE. Initially, PCI was performed, then the patient was transported to the vascular operating room, where he underwent CEE was performed according to the classical technique with modeling the reconstruction zone with a patch made of diepoxy-treated xenopericardium. Brain protection was achieved by invasive measurement of retrograde pressure. After CEE, the patient received a loading dose of clopidogrel 600 mg. The average follow-up period in the long-term period was 53.04 ± 17.1 months. Results. In the hospital period, only hemorrhagic complications were noted (n = 3; 4.68 %) while taking double antiplatelet therapy (acetylsalicylic acid + clopidogrel) and intraoperative heparin. In the long-term period, the leading position was occupied by a lethal outcome (n = 9; 16.6 %). Despite taking double antiplatelet therapy, in 6 (11.1 %) cases, stroke development was noted, in 1 (1.8 %) — MI. In 3 (5.5 %) patients, repeated unplanned revascularization was performed — CABG as a result of restenosis in the stent. The combined endpoint (death + stroke + myocardial infarction) was 29.6 % (n = 16). Significant risk factors for the development of complications in the hospital postoperative period were chronic renal failure (OR 3.7165; 95 % CI 1.2032–11.4800), III–IV functional class of angina (OR 21.9; 95 % CI 2.29–208, 8), a history of stroke (OR 6.82; 95 % CI 1.04–44.7). In the long term, the predictors of adverse events were bleeding (OR 2.02; 95 % CI 1.15–3.55), ejection fraction less than 50 % (OR 2.9; 95 % CI 1.47–5.7) and lesion trunk of the left coronary artery and more than three additional coronary arteries (OR 2.67; 95 % CI 1.27–5.59), and two or less affected coronary arteries (OR 0.34; 95 % CI 0.19–0.62). Conclusion. The efficiency and safety of hybrid revascularization in the volume of PCI + CEE has been proven in view of the minimum number of complications at different stages of follow-up.
