Management of aortic arch pathologies remains challenging. Open total arch replacements have been associated with significant morbidity and mortality owing to the need for cardiopulmonary bypass and circulatory arrest. On the other hand, aortic arch branched stent grafts are not widely available. In this context, hybrid techniques combining open arch debranching with endovascular graft placement have been identified as an attractive option in select patients. However, there still is a paucity of literature on their application and outcomes. A case is presented of an elderly frail patient diagnosed with a pseudoaneurysm of the aortic arch and who was successfully treated by an off-pump arch debranching followed by endovascular arch repair. This case highlights (i) the feasibility of hybrid debranching techniques, (ii) their technical challenges, and (iii) the need for long-term follow-up data.
