OBJECTIVES: The aim of this study was to assess risk factors for early neurological complications following thoracic endovascular aortic repair (TEVAR) for multiple thoracic aortic diseases using an aggregated dataset.
METHODS: The Study to Assess Outcomes After Endovascular Repair for Multiple Throacic Aortic Disease dataset included data from 6 studies evaluating Zenith thoracic endografts. Post hoc analysis identified early (30-day) neurological complications by TEVAR indication and corresponding risk factors.
RESULTS: The study included 594 TEVAR patients (67% male; mean age 66 ± 15 years) with thoracic aortic aneurysm (n = 329), ulcer (n = 56), acute (n = 126) or non-acute (n = 33) type B aortic dissection (TBAD) or blunt injury (n = 50). Overall early stroke rate was 3.5% (n = 21). Overall early paraplegia and paraparesis rates were 1.3% (n = 8) and 2.5% (n = 15), respectively. Multivariable analysis identified acute TBAD [versus others, odds ratio (OR) = 3.47, 95% confidence internal (CI): 1.41-8.52) and longer procedural time (OR = 1.33, CI: 1.02-1.73) as early stroke risk factors. Risk factors for paraplegia or paraparesis included more endografts deployed (OR = 2.43, CI: 1.30-4.55), older age (OR = 1.05, CI: 1.01-1.10) and higher preoperative serum creatinine (OR = 1.31, CI: 1.05-1.64). Endografts landing proximal to the left subclavian artery (LSA) increased stroke rate (versus distal to the LSA; 6.8% vs 2.3%, P = 0.014). Intraoperative LSA revascularization was performed in 20.9% of patients with endografts proximal to the LSA; revascularization did not significantly alter stroke rate (8.1% with revascularization vs 6.4% without, P = 0.72).
CONCLUSIONS: Acute TBAD and prolonged procedure time increased early stroke risk, while more endografts placed, age and preoperative renal impairment increased early paraplegia or paraparesis risk. For acute TBAD, endograft placement proximal to the LSA, but not LSA patency, increased stroke risk.
