The t-branch stent-graft system would have been primarily suitable for implantation in half of the patients. With additional maneuvers, the assisted suitability reached 63%. Further optimization and refinement of the device will probably lead to a shift toward off-the-shelf multibranched stent-graft exclusion of TAAAs.

The t-branch device, with the unique advantage of direct implantation without any delay for manufacturing, showed 100% technical success and comparable clinical outcomes to the traditional custom-made mbEVARs. Further long-term evaluation remains mandatory.

The chimney technique in the aortic arch proved highly and predictably successful, with a low rate of reinterventions.

The 30-day clinical outcome of 100 patients treated with a dual layer micromesh carotid stent (Roadsaver) shows promising results. The Roadsaver stent is a safe and effective device for endovascular treatment of subjects at high risk for carotid endarterectomy.
