Abstract
Purpose To describe a technique that can preserve renal perfusion in failed bridging stent implantation of renal arteries or as intentional procedure in emergency cases, when the (thoraco)abdominal aneurysm anatomy does not meet the criteria for instructions for use of an “off-the-shelf” graft. The technique is based on reversed or antegrade integration of a standard iliac side branch graft into the aortic stentgraft system, which allows cannulation of (accessory) renal vessels. Technique A standard iliac side branch prosthesis is deployed and re-sheathed in reversed direction on the back table. The endograft is then implanted in the unibody in analogy to an iliac limb. The iliac side branch is cannulated followed by target vessel cannulation and covered bridging stents are deployed for completion. Furthermore, an iliac side branch prothesis can also be used to preserve relevant accessory renal arteries, when implanted in delivered antegrade loading position. Conclusion The use of a reversed and antegrade iliac side branch technique to revascularize renal vessels is feasible and safe in selected patients. This technique may also allow to extend the range of an “offthe- shelf” (multibranch) stentgraft, when immediate treatment is required.
