The study evaluated the outcomes of TEVAR for aortic arch pathologies using surgeon modified fenestrated stent grafts, showing high technical success rate, low mortality, and low reintervention rate within 30 days post-operation. Follow-up data demonstrated good clinical outcomes at 24 months.
Objective: To evaluate the outcome of thoracic endovascular repair (TEVAR) for aortic arch pathologies with surgeon modified fenestrated stent grafts. Methods: A multicentre, retrospective study consisting of consecutive patients from seven centres treated with surgeon modified fenestrated stent grafts for aortic arch pathologies was conducted. A technique to align fenestrations and supra-aortic vessels was applied. Rates of technical success, mortality, complications, and re-interventions were evaluated. Results: Between February 2016 and January 2020, 513 consecutive patients with aortic arch pathologies received TEVAR with surgeon modified fenestrated stent grafts. The technical success rate was 98.6% (n = 506). In total, 626 fenestrations were created to revascularise 684 branch arteries of the aortic arch. There were 13 deaths and 15 reinterventions within 30 days of the operation. The estimated clinical success rate at 30 days was 94.4% (95% confidence interval [CI] 92.4 - 96.4), the estimated survival at 30 days was 97.5% (95% CI 96.1 - 98.9), and the estimated freedom from re-intervention at 30 days was 97.1% (95% CI 95.7 - 98.5). The median follow up was 27 (interquartile range 13 - 31) months. During follow up, there were five aortic related deaths, three non-aortic related deaths, and four deaths of unknown cause. Eighteen patients underwent re-intervention. The estimated clinical success rate at 24 months was 88.2% (95% CI 85.5 - 91.0), the estimated survival at 24 months was 94.9% (95% CI 92.7 - 97.1), and the estimated freedom from re-intervention at 24 months was 93.1% (95% CI 91.0 - 95.3). In total, 18 cases of stroke were recorded, including 12 within 30 days and six during follow up; six cases of retrograde type A aortic dissection were recorded, including five within 30 days and one during the follow up. Conclusion: TEVAR with surgeon modified fenestrated stent grafts for the treatment of aortic arch pathologies provides acceptable outcomes. Further follow up is required to confirm the benefits of this approach.
