To compare efficacy, safety, and short-term follow-up of thoracic endovascular aortic repair (TEVAR) with a newly designed stentgraft in patient subgroups with and without metachroneous aortic rerouting procedures.

Basis of the analysis is a prospective European multicenter monitored clinical registry (RESTORE) of patients treated with acute or elective TEVAR with the Relay stentgraft (Bolton Medical, Sunrise, FL, USA). Patients were assigned to one of two groups without (n=115) or with (n=80) a debranching procedure before stentgraft placement. Debranching procedures included: left subclavian transposition (n=47); subclavian and left carotid transposition (n=21); triple rerouting (n=12). For each group, endpoints were: technical success, complication rate, occurrence of endoleaks and mortality.

For the groups without and with debranching procedures, respectively, technical success was 98.3% and 97.5% (p=1.00). Complication rates were 19.1% and 16.3% (p= .71). Early endoleaks (within 30 days) occurred in 5.8% and 6.3% (p=1.0). Late endoleaks occurred in 8.2% and 11.1% (p= .58). Overall mortality was 11.3% and 11.7% (p= .77).

In the RESTORE dataset, no significant differences and, more importantly, similar outcome can be observed in the patient groups without and with supraaortic debranching procedures before TEVAR with the Relay stentgraft. The data support the hypothesis that debranching procedures are a safe option to extend TEVAR treatment into the aortic arch.
