Abstract

Objective: To assess practice patterns and short-term outcome after thoracic endovascular aortic repair (TEVAR), based on an international vascular registry collaboration.

Summary background data: TEVAR has become the primary surgical treatment modality for descending aortic pathologies, and has expanded to new patient cohorts, including the elderly.

Methods: Data on thoracic aortic aneurysms (TAA), type B aortic dissections (TBAD), and traumatic aortic injuries (TAI) treated with TEVAR from 2012 to 2016 were retrieved from registries and centers in 13 countries.

Results: Nine-thousand five-hundred eighteen TEVAR for TAA ( n = 4436), TBAD ( n = 3976) and TAI ( n = 1106) were included. The distribution of TEVAR procedures per pathology varied, with TAA repair constituting from 40% of TEVARs in the US to 72% in the UK ( P < 0.001).Mean intact TAA (iTAA) diameter varied from 59 (US) to 69 mm (Nancy, France) ( P < 0.001), 25.3% of patients having a diameter of <60 mm. Perioperative mortality after iTAA repair was 4.9%; combined mortality, stroke, paraplegia, and renal replacement therapy outcome was 12.8%. 18.6% of iTAA patients were ≥80 years old. Mortality was higher in this group (7.2%) than in patients <80 (3.8%) ( P < 0.001). After rTAA repair, perioperative mortality was 26.8%.Mortality was 9.7% after acute (within 14 days from onset of dissection) and 3.0% after chronic TBAD repair ( P < 0.001). Mortality after TAI was 7.8%, and depended on injury severity (grade IV (free rupture) 20.9%).

Conclusions: This registry collaboration provides a unique platform to evaluate cross-border patterns of use and outcomes of TEVAR. A common core dataset is proposed, to achieve harmonization of registry-based quality outcome measures for TEVAR.
