    Abstract:
    Purpose: To analyze aortic wall penetration of Heli-FX EndoAnchors after use in seal zones in the aortic arch or descending thoracic aorta during thoracic endovascular aortic repair (TEVAR). Materials and Methods: From May 2014 to May 2019, 25 patients (mean age 70.5±10 years; 16 women) were treated with TEVAR and adjunctive use of the Heli-FX device in 3 academic vascular surgery departments. Computed tomography scans were retrospectively reviewed to determine the location [arch or descending thoracic aorta (DTA)] of the EndoAnchors and the adequacy of aortic wall penetration, defined as adequate (≥2 mm), partial (<2 mm), or inadequate wall penetration (including loss). Endoleaks, reinterventions, and mortality were assessed. Results: A total of 161 EndoAnchors were deployed (median 7 per patient, range 4-9). Twenty-two EndoAnchors were place in the arch (zones 0-2) and 139 in the DTA (zones 3-5). A larger proportion of arch deployments (27%) had suboptimal penetration compared with the DTA (6.5%; p<0.005), resulting in a 91% adequate wall penetration rate for the series overall. Three EndoAnchors were lost (and only 1 retrieved) in 3 different patients, with no additional morbidity; thus, an overall deployment success rate of 88% was achieved. At a mean follow-up of 16.6±14 months, 4 patients required 5 (successful) reinterventions, including one for a type Ia endoleak treated with chimney TEVAR. One patient died 10 months after treatment due to endograft infection, without an opportunity for surgical correction. Conclusion: EndoAnchors have a higher risk of maldeployment in the arch, though this may be attributable to the small learning curve experience in this location. The best aortic wall penetration for this series was in the DTA, where EndoAnchors proved useful for distal endograft fixation during TEVAR.
