Perioperative Complications and Postoperative Mortality in Patients of Acute Stanford Type a Aortic Dissection with Cardiac Tamponade

Abstract

Abstract Objective The aim of the study was to analyze perioperative complications and postoperative mortality in patients of acute Stanford type A aortic dissection(ATAAD)combined with cardiac tamponade (TMP). Methods In this study, we identified a total of 242 ATAAD patients who underwent surgery from January 2016 to December 2020. Of the 242 patients, 44(18.2%) patients were combined with TMP and 198(81.8%) patients without TMP. We compared perioperative complications and postoperative mortality between the two groups. Results The postoperative mortality was significantly higher in patients with TMP (29.5% vs 14.1%, p = 0.014). The incidence of postoperative acute kidney injury (75.0% vs 51.5%, p = 0.005), acute hepatic injury (45.5% vs 20.7%, p = 0.001), cerebral infarction (27.3% vs 13.1%, p = 0.020), low cardiac output syndrome (50.0% vs 33.3%, p = 0.038) and respiratory failure (36.4% vs 22.2%, p = 0.049) in patients with TMP was significantly higher than those without TMP. Binary logistic regression analysis showed that age [odds ratio(OR) 1.063, 95% confidence interval (CI) 1.023∼1.105; p = 0.002], surgical time[odds ratio(OR)1.393, 95% confidence interval (CI) 1.006∼1.929; p = 0.046], cardiac tamponade[odds ratio(OR)3.010, 95% confidence interval (CI) 1.166∼7.767; p = 0.023], circulatory arrest time[odds ratio(OR)1.044, 95% confidence interval (CI) 1.001∼1.088; p = 0.045] were independent risk factors for postoperative mortality in ATAAD patients. Conclusions Cardiac tamponade increases the difficulty of perioperative management in ATAAD patients, the incidence of postoperative complications and postoperative mortality, which requires the cooperation of anesthesiologists, intensivists and surgeons to save and improve patients’ lives.
