Celiac Artery Coverage During TEVAR for Dissection and Acute Aortic Injury is Not Associated with Worse Outcomes

Published:December 15, 2022DOI:


      Studies have previously identified increased morbidity and mortality with celiac artery coverage during thoracic endovascular aortic repair (TEVAR) for aneurysmal disease. This study aimed to delineate the risks associated with celiac artery coverage in all patients undergoing TEVAR for dissection, trauma, or aneurysmal disease.


      Using the Vascular Quality Initiative database, we identified all patients undergoing TEVAR from 2012 to 2020 and categorized them based on the underlying pathology (aneurysm, dissection, or acute/trauma). Patients were excluded if their endograft was deployed distal to aortic zone 6 or if they had any preoperative/operative celiac revascularization procedure. Univariate, regression, and Kaplan–Meier analysis were performed for all 3 groups, focusing on postoperative complications and survival.


      There were 8,265 patients who underwent TEVAR over the 8-year study period with 142 (1.7%) having celiac artery coverage during their index procedure. Of those patients, the celiac artery was covered during TEVAR in 1.2% of patients with dissection, 1.3% with aneurysm, and 0.7% with trauma. On unadjusted analysis, celiac artery coverage in TEVAR for aneurysmal disease was associated with increased in-hospital mortality (16% vs. 5%, P < 0.001), 30-day mortality (33% vs. 23%, P = 0.029), any postoperative complication (excluding death) (42% vs. 25%, P < 0.001), and postoperative bowel complication (3% vs. 0.7%, P = 0.003). There were no differences in outcomes for patients treated with celiac coverage versus those without celiac coverage during TEVAR for dissection or trauma on univariate analysis. After risk adjustment, celiac artery coverage remained predictive of worse postoperative outcomes in patients with aneurysmal disease: in-hospital mortality (odds ratio [OR] = 3.6, confidence interval [CI] 1.8–6.9), 30-day death (OR = 1.6, CI 1.0–2.4), any postoperative complication (OR 2.2, CI 1.4–3.5), and bowel-specific postoperative complication (3.3, CI 1.0–10.8). There were no differences in patient outcomes for those treated with celiac coverage versus those without celiac coverage during TEVAR for dissection or trauma on multivariate analysis. Kaplan–Meier curves show a significant difference in overall survival based on pathology, specifically lower survival rates for patients with celiac coverage treated for aneurysmal disease. Cox regression analysis showed that celiac artery coverage for aneurysmal disease was associated with significantly increased hazard ratio affecting overall survival (hazard ratio = 2.6, P < 0.001), but there was no impact on survival in patients who underwent TEVAR with celiac coverage for dissection or trauma.


      Celiac artery coverage for patients with aneurysmal disease was correlated with a significant increase in postoperative morbidity, mortality, and lowers overall survival. However, for patients with dissection or acute/traumatic aortic pathology, celiac artery coverage does not portend worse outcomes.
