Abstract:
Objective:To investigate the perioperative complications and risk factors of postoperative death in patients with acute Stanford type A aortic dissection (ATAAD).Methods:The perioperative data of 228 patients with ATAAD who underwent continuous surgery in the Affiliated Hospital of Jining Medical University from January 2013 to July 2021 were retrospectively analyzed. The complications were analyzed. According to the survival within 30 days after surgery, they were divided into death group (24 cases) and survival group (204 cases). The risk factors of postoperative death were analyzed by univariate and multivariate logistic regression. The receiver operating characteristic (ROC) curve was drawed to evaluate the predictive efficacy of various risk factors on postoperative death of ATAAD patients.Results:The first three complications before operation were hypoxemia (10.1%, 23/228), pericardial tamponade (7.9%, 18/228), renal insufficiency (5.3%, 12/228), the first three complications after surgery were hypoxemia (75.8%, 173/228), renal insufficiency (26.8%, 61/228) and liver insufficiency (26.3%, 60/228). A total of 24 patients died, the fatality rate was 10.5%(24/228). Logistic regression analysis showed that age≥55 years old ( OR=7.733, 95% CI: 1.986-30.111, P=0.003), preoperative pericardial tamponade ( OR=5.641, 95% CI: 1.546-20.577, P=0.009), cardiopulmonary bypass time (CBP)≥200 min ( OR=1.008, 95% CI: 1.002-1.014, P=0.007) and postoperative renal insufficiency ( OR=5.875, 95% CI: 1.927-17.907, P=0.002) were independent risk factors for early death after ATAAD. The area under the ROC curves of joint prediction was 0.905 (95% CI: 0.820-0.950, P<0.01). The sensitivity and specificity of joint prediction were 88.4%, 76.5%, respectively. Conclusions:ATAAD has many perioperative complications and high mortality. Age≥55 years old, preoperative pericardial tamponade, CPB time≥200 min, and postoperative renal insufficiency were independent risk factors for postoperative death in ATAAD patients.
