Objectives: Patients surviving acute aortic dissection are at risk of developing a post-dissection thoraco-abdominal aortic aneurysm (PD-TAAA) during follow up, regardless of the type of treatment in the acute setting. Fenestrated and branched stent grafting (F/B-TEVAR) has been used with success to treat PD-TAAA, albeit reported only with short-term results. The aim of this study was to report mid-term results in a cohort of 71 patients. Methods: This was a retrospective analysis of a prospectively maintained database including all patients with PD-TAAAs who underwent F/B-TEVAR within the period January 2010 - April 2017 at two vascular institutions experienced in endovascular techniques. Results: A total of 71 consecutive patients (56 male, mean age 63.8 +/- 10.6 years) were treated. Technical success was achieved in 68/71 (95.8%) patients. In hospital mortality was four (5.6%) patients. Pen-operative morbidity was 19.6%. Three (4.2%) patients developed severe spinal cord ischaemia, one of these patients 12 months post-operatively. Mean follow up was 25.3 months (1-77 months). Cumulative survival rates at 12, 24, and 36 months were 84.7 +/- 4.5%, 80.7 +/- 5.1%, and 70.0 +/- 6.7%, respectively. Estimated freedom from re-intervention at 12, 24, and 36 months was 80.7 +/- 5.3%, 63.0 +/- 6.9%, and 52.6 +/- 8.0%, respectively. The main reasons for re-intervention were endoleak from visceral/renal arteries and iliac endoleak requiring extension. Target vessel occlusion occurred in 8/261 (3.1%) vessels (renal artery n = 4; superior mesenteric artery n = 2; coeliac artery n = 2). Mean aneurysm sac regression during follow up was 9.2 +/- 8.8 mm, with a false lumen thrombosis rate of 85.4% for patients with a follow up longer than 12 months. No ruptures occurred during follow up. Conclusion: F/B-TEVAR for post-dissection TAAA is feasible and associated with low peri-operative mortality and peri-operative morbidity. Mid-term results demonstrate a high rate of aneurysm sac regression. Rigorous follow up is required because of the significant re-intervention rate. Longer bridging covered stents for target vessels are advised.
