Simultaneous Carotid Artery Stenting and Coronary Artery Bypass Grafting in Urgent Patients: A Single Center Experience

<b>Background</b>: Coexisting coronary artery disease and critical carotid stenosis present challenges in revascularization, particularly in urgent cases requiring surgery. Combining carotid artery stenting (CAS) with coronary artery bypass grafting (CABG) has gained popularity. <b>Methods</b>: This study analyzed 36 patients who underwent simultaneous CAS and CABG from 2014 to 2024. CAS was performed first, with the patient awake for real-time neurocognitive assessment. A clopidogrel loading dose was administered three hours post-surgery. From postoperative day 1, dual antiplatelet therapy was initiated. <b>Results</b>: The median age was 72 years (64-77) and 22.2% were females. The median EuroSCORE II was 2.80 (2.06-3.58). Nine patients (25%) underwent associated procedures. The median cardiopulmonary bypass and cross-clamp times were 66 (54-89) and 51 (41-72) minutes. We observed no in-hospital mortality and no postoperative stroke. The median postoperative bleeding in 24 h was 500 mL and only one (2.8%) patient needed resternotomy for bleeding. The median ventilation time was 9 h (6-12). The median intensive care unit and postoperative length of stay were 2 (2-4) days and 8 (7-11) days, respectively. The median follow-up time was 6 years. Survival at 1, 5, and 10 years was 93.7%, 81.5%, and 60.2%, respectively, while freedom from PTCA/PCI at 1, 5, and 10 years was 100%, 96.7%, and 87.5%, respectively. <b>Conclusions</b>: Simultaneous CAS and CABG is a safe and effective procedure with low in-hospital mortality and morbidity. Our protocol carries a low risk of perioperative stroke. Antiplatelet therapy administration on the day of surgery does not increase the risk of postoperative bleeding.
