Retrograde Approach for Antegrade Inner Branches in a Precannulated Off-the-Shelf Multibranch Device.

PURPOSE The purpose of this technical note was to describe the application of the combination of precannulated branches and a femoral approach for bridging stent graft deployment in branched endovascular aneurysm repair. TECHNIQUE The technique is shown in a 65-year-old woman treated for thoracoabdominal aneurysm type I with endovascular repair using a multibranched device. The stent graft is an off-the-shelf device with 4 precannulated inner branches. Access to the precannulated branches is gained using a steerable sheath from retrograde femoral access instead of using access via the upper extremities. For this purpose, a 0.018" wire introduced to the precannulated tube is snared into the steerable sheath. Next, the steerable sheath is guided into a stable position inside the branch. With this technique, the implantation of this off-the-shelf multibranch device could be completed safe and quickly with a full femoral approach avoiding upper extremity access. CONCLUSION The combination of a precannulated multibranch stent graft with a full femoral approach for target vessel revascularisation is a feasible and quick method for complex endovascular repair.
