Abstract
OBJECTIVES: The gold standard for the treatment of pathologies of the aortic arch remains the open surgical reconstruction of the affected segments. However, endovas-cular treatment options have emerged that eliminate the need for invasive open surgery. Several endograft devices - with fenestrations or branches for the supraaortic vessels - are currently available to address different pathologies and anatomical variations. Parallel-graft techniques and in situ fenestrations expand the treatment options for emergent cases. In this selective review of the literature of 2020 and 2021, we summarize the current chances and challenges of endovascular aortic repair. CONTENT: Reported mortality rates range from 0 to 13.2 %. Although technical success rates for fenestrated and branched devices are promising (98 %), stroke rates remain a relevant issue (10 and 3 % for BTEVAR and FTEVAR respectively). The reported technical success rate for in situ fenestrations is also encouraging (94 %) and the stroke rates acceptable (5 %). Parallel-graft techniques are associated with high early and late endoleak rates (early 76 %; late 31 %), but still hold a valuable place in the treatment of emergent cases or in bail-out situations. SUMMARY AND OUTLOOK: The endovascular repair of the aortic arch expands the range of patients with pathologies of the arch eligible for treatment to those unfit for open surgery offering a minimally invasive, yet technically challenging procedure. More data and meta-analyses are needed to define the benefits and drawbacks of this promising treatment option in an aging population with increasing co-morbidities.
