The aim of the work: to evaluate the surgical outcomes of aortic arch correction in patients with concomitant cardiac pathology.
Materials and Methods. Between 2019 and 2023, surgical treatment was performed on 40 patients with aneurysms of the ascending aorta and aortic arch (or the arch alone). Coronary artery disease (CAD) was diagnosed in 8 (20.0 %) patients. The study participants were divided into two groups based on the scope of interventions. Group A (n=20, 50.0 %) included patients who underwent isolated correction of aortic arch aneurysms or dissecting aneurysms without concomitant cardiac interventions. Group B (n=20, 50.0 %) comprised patients who underwent additional cardiac surgical procedures, including coronary artery bypass grafting (CABG) in 3 (15.0 %) patients with CAD. Surgical interventions in Group B were characterized by longer duration (597.2 minutes vs. 465.4 minutes in Group A), extended cardiopulmonary bypass time (304.5 minutes vs. 264.6 minutes), and longer aortic cross-clamping time (175.0 minutes vs. 138.3 minutes).
Results. A total of 52 postoperative complications were recorded among the study cohort. The incidence of ischemic spinal cord complications was significantly higher in Group B (5 cases) compared to Group A (1 case). Patients who underwent CABG required special attention, as this subgroup demonstrated a significantly higher risk of postoperative ischemia of the spinal cord. The shorter duration and single-stage nature of these procedures significantly reduce the risks of complications and mortality, which is particularly crucial for patients with comorbidities that complicate the clinical course of the disease. Analysis of the obtained data revealed significantly longer operative time, cardiopulmonary bypass duration, aortic cross-clamping time, and higher blood loss in patients with concomitant pathologies compared to those with isolated aortic arch pathology (p<0.05).
Conclusions. The frequency of postoperative ischemia of the spinal cord correlates with the duration of the operation and blood loss. Patients with concomitant pathologies, especially in the presence of coronary artery disease requiring surgical correction, have a higher risk of postoperative complications.
