Objective: The purpose of this multicentre study was to analyse the outcome of thoracic endovascular aortic repair (TEVAR) in patients with ruptured descending thoracic aortic aneurysm (rDTAA). Methods: This is a nationwide retrospective study including all patients who underwent TEVAR for rDTAA at six major vascular university centres in Sweden between January 2000 and December 2015. Outcome measures were analysed using Kaplan–Meier estimator and multivariable Cox regression. Results: There were 140 patients (age [mean ± SD] 74.1 ± 8.8 years; 56% men; aneurysm size 64.8 ± 19 mm), with rDTAA. In 53 patients (37.9%), the left subclavian artery was covered, and in 25 patients (17.9%) arch vessel revascularisation was performed. In total, 61/136 patients (45%) had a major complication within 30 days post TEVAR. Stroke (n = 20; 14.7%) was the most common complication, followed by paraplegia (n = 13; 9.6%) and major bleeding (n = 13; 9.6%). TEVAR related complications during follow up included endoleaks 22.1% (30/136; 14 type 1a, six type 1b, 10 not defined). In total, re-interventions (n = 31) were required in 27/137 (19.7%) patients. The median follow up time was 17.0 months (range 0–132 months). The Kaplan–Meier estimated survival was 80.0% at one month, 71.7% at three months, 65.3% at one year, 45.9% at three years, and 31.9% at five years. Age (HR 1.03; 95% CI 1.00–1.07; p = .046), history of stroke (HR 2.35; 95% CI 1.19–4.63; p = .014), previous aortic surgery (HR 2.11; 95% CI 1.15–3.87; p = .016) as well as post-operative major bleeding (HR 4.40; 95% CI 2.20–8.81; p = .001), stroke (HR 2.63; 95% CI 1.37–5.03; p = .004), and renal failure (HR 8.25; 95% CI 2.69–25.35; p = .001) were all associated with mortality. Conclusions: This nationwide multicentre study of patients with rDTAA undergoing TEVAR showed acceptable short- but poor long-term survival. Adequate proximal and distal aortic sealing zones are important for technical success. High risk patients and post-operative complications need to be further addressed in an effort to improve outcome.
