Introduction and importance: Elderly and frail patients with thoracic aortic aneurysms (TAAs) near to origins of cervical arteries present facing challenges with aortic arch replacement with cardiopulmonary bypass, and traditional tube-type stent-grafts are also inadequate for transcatheter endovascular aortic repair (TEVAR). Thus, necessitating precise treatment with fenestrated stent-grafts from zone 0. This approach is crucial for achieving favorable postoperative outcomes without compromising activities of daily living (ADL).
Case presentations: An 85-year-old-man admitted to the hospital for treatment of a large TAA. While arch replacement is a definitive procedure, it is highly invasive, and the postoperative ADL are expected to be significantly lower than preoperative levels. Therefore, we performed a debranching TEVAR from Zone 0 with fenestrated stent-graft. The patient was discharged from the hospital on the 11th postoperative day.
Clinical discussion: In frail and elderly patients for whom conventional surgery may not be viable, TEVAR emerges as a preferred alternative. However, TEVAR of TAA proximal to the aortic arch continues to pose challenges, necessitating meticulous attention to the cervical branches in the intervention strategy. While surgical intervention in these patients necessitates careful consideration of its suitability, including the potential for postoperative enhancement in ADL, the use of fenestrated stent-grafts from Zone 0 emerges as one of the treatment modalities.
Conclusion: The authors present a very elderly case in which fenestrated stent-grafts were used to avoid aortic arch replacement for a large aortic arch aneurysm, resulting in a good postoperative course with no decline in ADL.
