The involvement of the aortic arch in thoracic aortic aneurysms (TAA), or acute aortic dissections (AAD), represents a challenging clinical entity, mandating a meticulous surgical plan, tailored to each individual case. The advent of endovascular techniques and the introduction of modern arch protheses have led to the implementation of the frozen elephant trunk (FET) technique. This one-step hybrid operation consists of a total aortic arch replacement combined with an antegrade delivery of a stent–graft for the descending aorta, which acts as a proximal landing zone facilitating a potential distal endovascular reintervention. In this manner, this technique addresses acute and chronic arch disease with an acceptable morbidity and mortality. Several FET prosthetic devices are available on the global market and have exhibited favourable outcomes, although with some disadvantages in complex cases; similarly, the hybrid procedure described in this review has also been associated with complications, such as coagulopathy and neurological and graft-related events. The purpose of this review is to thus provide key insights into successful hybrid aortic arch replacements and to discuss useful tips and relevant considerations regarding its use.
