Distal stent graft-induced new entries following frozen elephant trunk procedure

The frozen elephant trunk procedure is a well-established treatment option for patients with aortic pathologies involving the aortic arch. Planned, anticipated, and unplanned aortic reinterventions are common. In patients with aortic dissections, the comparably high risk for the development of distal stent graft-induced new entries (dSINE) has been identified as one cause. These can develop at any time following the frozen elephant trunk procedure. Endovascular treatment is generally feasible and safe. Continuous follow-up of all patients after the frozen elephant trunk treatment, ideally in a dedicated aortic outpatient clinic, is mandatory.
