Midterm Outcomes of In Situ and In Vitro Fenestrated Stent-Grafts for Endovascular Repair of Aortic Arch Pathologies

For patients with aortic arch pathologies, in situ and in vitro fenestration techniques revealed comparable early and midterm results. Further evaluation of more patients with longer follow-up is needed to substantiate these results.Clinical ImpactOur single-center retrospective cohort study conducted a comparative analysis of in-situ fenestration versus in-vitro fenestration techniques in patients with aortic arch pathologies.Comparative studies between the two approaches are still limited. Our results provide a basis for the selection of in-situ or in-vitro fenestration techniques for endovascular repair of aortic arch lesion.
