Hybrid repair of aortic arch aneurysm in high-risk patients.

Objectives: Morbidity and mortality after conventional surgery of aortic arch aneurysms remain high. Alternative techniques are the subject of this report.

Methods And Results: Open surgery requires cardiopulmonary bypass and hypothermic circulatory arrest. Thoracic endovascular aneurysm repair has a less invasive therapeutic alternative. The number of high-risk patients has considerably increased over the past decade. The proximity of the aneurysm to the supraaortic vessels makes it difficult to achieve a satisfactory proximal landing zone for endovascular stenting. Two methods have been proposed to address this issue: branched stent grafts and extraanatomic bypass, defined as a hybrid approach, which combines aortic debranching and endovascular procedures. Experience with hybrid repair is limited. Today there are no formal guidelines for the management of aortic arch aneurysm in high-risk patients.

Conclusion: Hybrid repair of aortic arch aneurysm in high-risk patients is a feasible and safer option.
