Özet
Background: Cerebral protection during aortic surgery is crucial for improving surgical outcomes and reducing neurological complications. Selective antegrade cerebral perfusion (SACP) is increasingly used, and innominate artery (IA) side graft cannulation presents an innovative alternative to conventional axillary artery cannulation, with the potential to reduce complications associated with the latter. Methods: In this retrospective study, 196 patients who underwent proximal aortic surgery with IA graft cannulation for SACP between January 2021 and June 2024 were analyzed. Demographic data, intraoperative parameters, and postoperative outcomes were evaluated. Complications such as new stroke, postoperative delirium, mortality, and acute renal failure (ARF) were assessed. Results: The median age of the patients was 63 years, and 18.37% underwent emergency surgery for Type A acute aortic dissection (TAAAD). The most frequently performed surgical procedure was ascending aorta and hemiarch replacement (36.74%). The median cardiopulmonary bypass, cross-clamp, and SACP durations were 120.5, 93, and 23 min, respectively. The postoperative mortality rate was 3.06%, stroke rate was 2.04%, delirium rate was 9.18%, and ARF rate was 3.06%. All cases of delirium resolved spontaneously within 2-3 days. The mortality rate among Marfan syndrome (MFS) patients was 4.35%, with no reported stroke cases in this group. Conclusions: IA graft cannulation is a safe and effective method for providing SACP in aortic surgery, particularly in high-risk patient groups such as those with TAAAD and MFS. This technique ensures optimal cerebral perfusion, minimizes neurological and systemic complications, and enhances surgical efficiency by reducing operative duration. However, large-scale, multicenter, and prospective studies are needed to evaluate its long-term efficacy and safety.
