BACKGROUND: The aim of the study was to analyze the clinical characteristics of patients with Stanford type B aortic dissection (TBAD) and risk factors for poor prognosis after thoracic endovascular aortic repair (TEVAR).
METHODS: Clinical records for patients with TBAD presenting to a medical center between March 1, 2012 and July 31, 2020 were reviewed. Clinical data including demographics, comorbidities, and postoperative complications were obtained from electronic medical records. Comparative analysis and subgroup analysis were performed. A logistic regression model was used to analyze prognostic factors in patients with TBAD after TEVAR.
RESULTS: TEVAR was performed on all 170 patients with TBAD, and poor prognosis was identified in 28.2% (48/170) of cases. Patients with a poor prognosis were younger (38.5 [32.0, 53.8] years vs. 55.0 [48.0, 62.0] years, P < 0.001), had higher systolic blood pressure (SBP) (138.5 [127.8, 152.8] mm Hg vs. 132.0 [120.8, 145.3] mm Hg, P = 0.013) and more complicated aortic dissection patients (19 [60.4] vs. 71 [41.8], P = 0.029) than those without a poor prognosis. According to the results of binary logic regression analysis, the possibility of a poor prognosis after TEVAR decreased with each 10 years increase in age (odds ratio: 0.464, 95% confidence interval: 0.327-0.658, P < 0.001).
CONCLUSIONS: There is an association between younger age and a poor prognosis after TEVAR in patients with TBAD, with the condition that those with poor prognoses have higher SBP and more complicated cases. In younger patients, postoperative follow-up should be more frequent, and complications should be managed in time.
