Aortic Stent Graft Treatment in a Medium-Size Aortic Center Performed by a Cardiac Surgeon Only-The 9 Years Experience in Poland.

Background: The incidence of thoracic aortic aneurysms is estimated at 3.0-8.3/100,000 persons per year. There is a lack of reports in the literature on the outcomes of small- and medium-sized thoracic endovascular aortic repairs. The aim of this study is to present the results of thoracic endovascular aortic repairs at a single medium-sized center performed exclusively by a cardiac surgeon. Methods: Ninety patients who had undergone aortic stent graft implantations for the treatment of thoracic aortic anomalies were comprehensively, retrospectively evaluated. The detailed preoperative, surgical, and postoperative parameters of the patients, including the survival rate up to five years, were recorded and further analyzed. Results: The patients' Euroscores were four (2.1-9). The 30-day mortality rate was 8.9%, the 1-year mortality rate was 15.6%, and the 5-year mortality rate was 38.9% for all causes. Postoperative complications were observed in 10% of the patients. Statistically significant differences were observed between the urgency of surgery at 30 days and survival at one year, but not at five years. The most common complications were related to respiratory (4.4%), renal (3.3%), and neurological (3.3%) dysfunction. Conclusions: Thoracic endovascular aortic repair can be safely performed in small- and medium-sized centers with optimal long-term results.
