Two year follow-up results of thoracic endovascular repair with Relay Bolton endoprosthesis: the experience of the Italian participants of RESTORE I registry

Aim. endovascular procedures for thoracic aorta are widely used in different pathologies: aneurysms, acute and chronic dissections, penetrating aortic ulcers, intramural hematomas, blunt trauma. The aim of this study is to present the Italian experience in the RESTORE I Registry. Methods. RESTORE is a perspective, non randomized, European multicentric Registry designed to evaluate technical and clinical outcome from patients treated with Relay (TM) stent-graft. Threre hundred and four patients were enrolled all over Europe. Italy contributed with 146 patients (48%) in 8 major referral centres. The purpose of the registry was to collect data about patients undergoing thoracic graft endoprosthesis with Relay (TM) Bolton. Including indications were degenerative acute and chronic aneurysm, type B acute and chronic dissections, intramural hematomas, penetrating aortic ulcers, pseudoaneurysms and blunt trauma. Results. Patients were 120 males (82.2%) and 26 females; 102 patients (70.3%) were classified as ASA class III or more. The most common aortic pathology treated was aneurysms (63.0%), followed by dissection (22.6%). Technical success was achieved in 144 patients (98.6%); 139 patients (95.21%) reported no endoleaks at discharge. No neurologic complications were found in 136 patients (93.15%): a overall spinal cord ischemia rate of 5.48% and a overall stroke rate of 1.37%. The 30-day mortality rate was 18.6% (8/43) in the acute group and 9.7% (10/103) in the chronic one. At 2 years the overall survival rate due to any cause was 68.54%. Conclusion. Realy (TM) is a safe and accurate graft to treat different thoracic aorta pathologies with acceptable mortality and morbidity and with low stroke rate.
