Editor's Choice - Single Centre Midterm Experience with Primary Fenestrated Endovascular Aortic Aneurysm Repair for Short Neck, Juxtarenal, and Suprarenal Aneurysms.

Objective: The use of fenestrated stent grafts to treat short neck, juxta- and suprarenal aortic aneurysms is increasing worldwide, but midterm outcome reports are scarce. This study aimed to report peri-operative results and midterm outcomes after five years from a single centre.
Methods: Patients treated with primary fenestrated endovascular aortic aneurysm repair (FEVAR) for short neck, juxta- or suprarenal aortic aneurysms within the period January 2010 to May 2020 with follow up in the centre were included. Early (technical success, operative mortality, spinal cord ischaemia) and five year outcomes (cumulative survival, freedom from aortic related death, target vessel patency, target vessel instability [TVI], re-interventions) were analysed.
Results: A total of 349 patients (313 male, mean age 72.3 ± 7.7 years) were included in the study. Technical success was 98% (342/349). The thirty day mortality rate was 0.9% (3/349). Estimated survival at five years was 69.3 ± 3.1%. Freedom from aneurysm related death at five years was 98.8% ± 0.7%. Estimated target vessel patency at five years was 98.7 ± 0.4%. Estimated freedom from TVI at five years was 97.2 ± 0.6%. Estimated freedom from re-intervention at five years was 86.5 ± 2.3%. Survival did not differ significantly between patients with and without re-interventions (p = .088).
Conclusion: Midterm results of FEVAR remain good as indicated by sustained target vessel patency and low aortic related mortality rates. An important proportion of patients require re-interventions, which do not have a negative impact on midterm survival.
