Overview
To assess safety and feasebility of the "safe-line" technique in a multicenter international collaboration.
Description
To assess safety and efficacy of a technique for temporary aneurysm sac re-perfusion (TASreP) after total endovascular exclusion of TAAA, using a guide-wire left into the aneurysm sac. The technique can be applied both in elective that urgent cases.
The guide-wire aim to be a "safe-line" for fast temporary trans-sealing aneurysm sac re-perfusion in case of SCI occurring in the early post-operative period (48-to 72h).
Before completing exclusion, from the percutaneous femoral access, a second buddy-wire (V-18 guidewire; Boston Scientific) is advanced and left posterior to the endograft into the aneurysmal sac; through the main guide-wire, the final aneurysm exclusion is completed with distal stent-graft deployment and the femoral access sealed with Proglide leaving in place the sole V.018 draped in a sterile fashion. In the case of SCI occurrence in the post-operative period up to 48-72 hrs, the trans-sealing V.18 "safe-line" can be rapidly exchanged with a 6F/65 cm long Destination cm guiding sheath (Terumo) and positioned into the aneurysmal sac; this can be connected to a 6F introducer from the contralateral femoral artery and the sac perfused in a retrograde fashion.
