Sheath-Anchoring for Rail Guidewire Technique to Advance and Deploy Thoracic Endograft in Hostile Anatomy

Background: To describe a bailout technique to advance and precisely deploy thoracic endograft in the ascending aorta in case of difficulty crossing the aortic arch.Case Reports: A 73-year-old man presented with a large ruptured aneurysms in the descending aorta. During the TEVAR, stent-graft passage through the aortic arch was impossible due to the severe tor tuosity of the aor ta. The problem has been resolved using the sheath-anchoring rail guidewire (SARG) technique.Results: Through an axillary access, a snare was used to capture the stiff wire from the femoral access. A sheath was advanced over the stiff wire to the ascending aorta and placed there. By exploiting the grip of the sheath on the stiff in the ascending aorta, it was possible to handle the tension, move the delivery system through the arch and carefully deploy the graft.Conclusion: The SARG is a simple and quick learning technique which can be useful for Physicians dealing with complex aortic arch anatomy.
