Abstract/OtherAbstract:
OBJECTIVE: Although rare, aortic dissection is one of the most devastating, but least studied, intraoperative complications. The objective of this study was to assess risk factors of aortic dissection and assess outcomes in patients with aortic dissection experience. METHODS: A study from a 10-year hospitalization cohort (N = 12,907) with prospective data collection was conducted. Patients without aortic dissection were matched to 33 aortic dissection patients 3:1 on the type of procedure. The study examined 24 potential confounding risk factors and 12 outcome variables. RESULTS: Univariate analysis on potential confounding risk factors revealed two significant risk factors. There was a significant difference between aortic dissection and nonaortic dissection patients with New York Heart Association (NYHA) functional class (p = 0.03). Patients with aortic dissection were more likely to be in Class I or II. Patients with aortic dissection had significantly longer perfusion time (p = 0.008). There was a significant difference between patients with and without aortic dissection on four outcome variables. Patients with an aortic dissection were more likely to need prolonged ventilation (p = 0.046), have renal failure (p = 0.005), require intraaortic balloon pump (IABP) (0.043), and have a higher mortality rate (p < 0.001). CONCLUSION: Aortic dissection occurs infrequently during coronary artery bypass grafting, but is a devastating complication and greatly increases morbidity. Although few patients dissect intraoperatively, this study attempted to identify predictors that may label a patient as high risk for possible aortic dissection. Although two factors in this study were statistically significant, they are not reliable preoperative predictors of high-risk patients that can be used to screen patients and help prevent aortic dissection and its sequela.
