Orthotopic branched endovascular aortic arch repair in patients who cannot undergo classical surgery.

OBJECTIVES

Our goal was to assess the results after orthotopic branched endovascular aortic arch repair using a new double-branch endoprosthesis in patients with thoracic aortic disease affecting the aortic arch who cannot undergo classical surgery.

METHODS

Within a 4-year period, 15 patients with thoracic aortic disease affecting the aortic arch were treated with the Bolton Relay plus double-branch endoprosthesis (Bolton Medical, Sunrise, FL, USA). We assessed clinical outcome, occurrence of endoleaks and the need for secondary interventions. The median logistic EuroSCORE I level was 13.6 (4.2; 22.8).

RESULTS

The in-hospital mortality rate was 6.7%. A disabling stroke was observed in 1 (6.7%) patient, whereas non-disabling strokes occurred in 2 (13.3%) patients. Type I and III endoleaks occurred in 6.7%. The median follow-up period was 263 (1st quartile 84; 2nd quartile 564) days. Four patients died during the follow-up period. Aortic-related survival was 100%.

CONCLUSIONS

Orthotopic branched endovascular aortic arch repair using the Bolton Relay Plus double-branch endoprosthesis is a safe and feasible technique enriching the armamentarium to treat patients with thoracic aortic disease who cannot undergo classical surgery. Aortic-related survival is excellent, and the occurrence of disabling stroke and endoleaks warranting treatment is low. Further studies are needed to assess the long-term durability of this new method.
