PURPOSE: The aim of this study was to evaluate the efficacy and safety of thoracic endovascular aortic repair with a newly designed Relay thoracic stent graft (Bolton Medical, Sunrise, FL). DESCRIPTION: Between 2005 and 2007, 22 patients (71.8 +/- 8.5) received 24 stent grafts. Indications were aneurysms (n = 13), penetrating atherosclerotic ulcers (n = 7), and dissections (n = 2). Due to the proximity of the lesions to the aortic arch, rerouting procedures (ie, subclavian transposition [n = 1], double transposition [n = 12], and total arch rerouting [n = 6] were performed pre-interventionally; three patients did not undergo rerouting). All patients were followed-up with a computed tomographic scan of the entire aorta at discharge, 3 months, 6 months, and annually thereafter (mean follow-up, 13 months). EVALUATION: Primary technical success was obtained in 20 of 22 patients, with one persisting type I endoleak and one asymptomatic type II endoleak. One patient died due to malignant arrhythmia 3 days after stent-graft placement. During follow-up, 1 nonaortic related death was observed. No additional endoleaks were observed. Finally, all supra-aortic rerouting procedures remained patent. CONCLUSIONS: In the treatment of degenerative disease of the descending aorta and the aortic arch, the Bolton Relay stent graft offers acceptable efficacy and safety in short-term follow-up.
