Endovascular repair of the descending aorta and the aortic arch with the Relay stent graft.

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.
