Synopsis
Dr. Sean Lyden serves as the Chairman of Vascular Surgery at Cleveland Clinic. Sean starts off the discussion by conveying the severity of SFA chronic total occlusion (CTO) and walks us through what PTAB therapy is. We then cover the steps and general principles of using the DETOUR technology.
Throughout the episode, Sean and Sabeen discuss the structure and key takeaways of both the DETOUR 1 and DETOUR 2 trials, held in Europe and the United States respectively. They also cover major questions, such as DVT and PE risk, patency of femoral vein following DETOUR intervention, and overall device cost.
We conclude the episode with future directions of the now FDA-approved DETOUR device, and when and how vascular and interventional physicians can incorporate the new technology into their practice. Sean and Sabeen also contrast prior treatment options with the recent DETOUR trials to highlight how longer calcified / occluded SFA lesions now have a viable, effective, and safe endovascular treatment option.

[Dr. Sean Lyden]
The easiest way to think of the Detour System is it's a way to create a percutaneous femoral to popliteal bypass. You're going to start in the arterial side, you need basically just enough opening in the origin of the SFA to get a catheter or wire in at least 3 centimeters. Then it uses a spring loading proprietary crossing device which will puncture out of the superficial femoral artery into the femoral vein, and then travel down the femoral vein, and then use that same crossing device to cross back from the femoral vein into the popliteal artery. Then you're basically lining that segment with a PTFE stent graft, usually two or three stent grafts to cover that segment.
