Physician-Modified and In Situ Fenestrated Stent Grafts in Zone 0 for Aortic Arch Pathology After Ascending Aortic Replacement

Our experience of using different total endovascular techniques for selective patients with arch pathologies who may be unfit or too risky for reopen surgery revealed favorable initial results. In addition, these techniques are promising options for urgent arch pathologies without availability of custom-manufactured devices. Durability concerns will need to be assessed in additional studies with long-term follow-up.Clinical ImpactThe use of physician-modified and in situ fenestrated stent grafts in zone 0 landing for aortic arch pathologies in patients with prior open ascending aortic replacement is effective in endovascular therapy. This innovation enables clinicians to offer an alternative option to high-risk patients, potentially reducing morbidity and mortality. It underscores the feasibility of tailored endovascular therapy in complex aortic diseases, where customized devices may not be available.
