Introduction: Thoracic endovascular aortic repair (TEVAR) has rapidly developed to the primary treatment modality for most pathologies of the descending thoracic aorta. Practice patterns and short-term outcome regarding TEVAR was assessed based on an international vascular registry collaboration. Methods: Data on TEVAR procedures were retrieved from national, regional and centre-specific registries in eight countries located in Europe and Australasia. All thoracic aortic aneurysms (TAA), aortic dissections (AD), and traumatic aortic injuries (TAI) treated with TEVAR during the period 2012-2016 were included. Results: 1919 TEVAR procedures performed because of TAA n=994, AD n=692 and TAI n=233 were included. The distribution of TEVAR procedures for each pathology differed between countries (p< 0.001), Figure 1. Mean age was TAA 71.6, AD 63.5 and TAI 47.1 years (p< 0.001). The majority of the treated patients were men; TAA 64%, AD 77%, TAI 79%. The proportion of ruptured TAA varied from 9% to 39% between countries (p=0.001). Mean maximal aortic diameter varied from 60.1-69.1 mm for intact aneurysms (p=0.018). Mean maximal aortic diameter for ruptured aneurysms was 68.6 mm. 68% of AD were treated in acute and 32% in chronic phase, the proportions did not differ significantly between countries. Indications for TEVAR of acute dissection were: refractory pain 27%, visceral ischemia 24%, rupture 21%, dilatation 18%, extremity ischemia 5% or other reasons 5%. Chronic dissection was treated because of dilatation 75%, refractory pain 9%, rupture 6%, extremity ischemia 2%, visceral ischemia 1% or other reasons 7%. Mean maximal aortic diameter was 45.1 mm for acute and 61.6 mm for chronic dissection. 93% of TAI were treated emergently. The rates of perioperative mortality, stroke, paraplegia and renal failure requiring renal replacement therapy are presented in Table I. The rates of perioperative mortality and renal failure differed significantly depending on indication for TEVAR. Conclusion: The results of this broad registry-based analysis of TEVAR indicate that there are international differences in clinical practice. Short-term outcome after TEVAR depends on pathology, and is adequate compared with previous studies on endovascular and open surgical repair of thoracic aortic pathology.Table IPerioperative mortality and complicationsTable IPerioperative mortality and complications Disclosure: Nothing to disclose
