Objectives: The main purpose of this study was to identify the risk factors, including gender, comorbidities, and seasonal correlation, with the development of aortic dissection. We also aimed at determining the most common postoperative complications. Materials and methods: We conducted a retrospective study analyzing the records of 38 patients who had been admitted postoperatively to the Department of Anesthesiology and Intensive Care Unit at the University Hospital of Split during the period of January 2019 to December 2021. The collected data was analyzed using Microsoft Excel for the descriptive data, while for the statistical analysis, we have used MedCalc Statistical Software version 20.013 (MedCalc Software Ltd, Ostend, Belgium). Results: Most of the patients were male (81.6%). The mean deviation for age was 66 years. The mean deviation for the length of stay in the ICU was 5 days. The correlation between the age of the patient and the length of stay in the ICU was statistically significant (p<0.0001). The majority of patients (84.2%) had a history of arterial hypertension. The seasonal correlation was found to have uneven distribution. The most common postoperative complication was found to be acute kidney injury occurring in 26.32% of patients. Conclusion: We concluded that males present more often with aortic dissection. Patients more often have a history of comorbidity such as arterial hypertension. Acute kidney injury is the most common postoperative complication. The age of the patient correlates with the length of hospital stay. However, the sample size was to small to determine the statistical significance between the risk factors and the postoperative outcomes, a larger study is needed for further evaluation.
