ABSTRACT
BACKGROUND:
The management of residual aortic dissection after initial type A repair with the Frozen elephant trunk technique remains mostly unexplored. This work aimed to evaluate endovascular second-stage surgery for patients with residual aortic dissection.METHODS:
A retrospective analysis of consecutive patients that underwent Type A aortic repair with Frozen elephant trunk, followed by a second-stage endovascular procedure was done from March 2016 to December 2021. The primary outcome was aortic-related adverse events or mortality, and secondary outcomes were aortic remodeling and perioperative complications. Remodeling was assessed by comparing the difference in ratios for true lumen/total aortic diameters on pre-operative and follow-up scans.RESULTS:
Thirty-four patients underwent second-stage surgery after Type A repair during the study period (7 thoracic endovascular aortic repair extensions, 1 STABLE/PETTICOAT, and 26 STABILISE). Median follow-up was 23 months (range 2-66 months). There were no perioperative deaths or major complications and 1 reoperation for left subclavian re-embolization. At the last follow-up, there was no aortic-related mortality. There were 5 aortic-related adverse events, including another subclavian re-embolization and a preplanned open conversion. Risk factors were connective tissue disorders (P = 0.01) and aortic aneurysms >55 mm (P = 0.03). Distal remodeling reached statistical significance in all segments (P < 0.01) and was greater for patients treated with the STABILISE technique when compared to extended thoracic endovascular aortic repair (P = 0.01).CONCLUSIONS:
Second-stage endovascular management of residual aortic dissection after initial Frozen elephant trunk repair showed excellent perioperative and good midterm outcomes and induced significant remodeling of the entire aorta in most cases, particularly with the STABILISE procedure.
