      Abstract

      To report our initial experience with total and subtotal endovascular aortic arch reconstruction combined with supra-aortic vessel transposition in high-risk patients and to present a new morphological classification of thoracic aortic lesions for patient and procedure selection. Among 80 patients treated with thoracic stent-grafts at our department between 1997 and 2003, 8 patients (6 men; mean age 71 years, range 45-81) unfit for open repair were not candidates for standard endovascular repair due to inadequate proximal landing zones on the aortic arch. Commercially available endografts (Excluder, Zenith, Endofit, Talent) were used to repair the arch after supra-aortic vessel transposition was performed. The endograft was implanted transfemorally or via an iliac Dacron conduit graft with standardized endovascular techniques and deployed during intravenous adenosine-induced asystole. The imaging data from all thoracic endograft patients was analyzed to classify thoracic and thoracoabdominal lesions according to a 4-level anatomical system. Deployment success was 100% after staged supra-aortic vessel transposition, but 1 patient died of endograft-related rupture of the proximal aortic arch. There was no neurological complication. Mean follow-up was 16 months (range 1-36). Patency of all endografts and conventional bypasses was 100%, and no migration was observed. One minor type II endoleak was demonstrated. Initial results are encouraging for endovascular aortic arch repair in combination with supra-aortic transposition in selected high-risk patients with complex aortic pathologies.
