Abstract

ChEVAR. Angiología [online]. 2022, vol.74, n.2, pp.86-87.  Epub Apr 25, 2022. ISSN 1695-2987.  https://dx.doi.org/10.20960/angiologia.00396.

The chimney technique for endovascular aneurysm repair (ChEVAR) emerged as a rescue technique to revascularisation or preserving covered critical branches during aortic endografting. ChEVAR adoption grew steadily over the years, but suffered a notorious absence of strong scientific evidence to underpin the technique. This all changed in 2015 with the publication of clinical results in the landmark PERICLES Registry, which demonstrated excellent outcomes in a wide range of complex-anatomy aneurysm patients treated by parallel-graft experts at key medical centres in Europe and the USA.

Critically important (and often overlooked) is the observation that the majority of ChEVAR gutter endoleaks detected on completion angiography have resolved spontaneously by the time the first postoperative computed tomography angiography is performed.

It is encouraging to see that ChEVAR has been included in the latest 2019 Abdominal Aortic Aneurysm Treatment Guidelines from the European Society for Vascular Surgery, where the technique is recommended in urgent cases and when fenestrated repair is unfeasible or contraindicated.
