Abstract:
The off-the-shelf t-Branch device (Cook Medical, Bloomington, Ind) significantly advanced the endovascular treatment of ruptured thoracoabdominal aortic aneurysms. Improved techniques for expeditious implantation of the t-Branch may improve clinical outcomes for this emergent procedure. Currently, implantation is described using axillary and femoral access. We describe the repair of a ruptured thoracoabdominal aortic aneurysm exclusively through femoral access aided by a steerable sheath and newer generation, low-profile bridging stents.
