Percutaneous Transmural Arterial Bypass (PTAB)
PTAB: A Groundbreaking Alternative for PAD Patients
Peripheral Artery Disease (PAD) and the Challenge of Limb Ischemia
Peripheral Artery Disease (PAD) is a progressive vascular condition that affects millions, with critical limb-threatening ischemia (CLTI) emerging as one of its most severe consequences. The femoropopliteal arterial segment, particularly the superficial femoral artery (SFA), is often severely compromised in PAD patients, leading to pain, non-healing wounds, and the looming risk of amputation.
Traditional treatment options for advanced PAD range from angioplasty, stenting, and atherectomy to open surgical bypass, which has long been considered the gold standard. However, open bypass surgery comes with higher risks, increased costs, and longer recovery periods. This is where PTAB provides a revolutionary alternative for patients seeking a less invasive yet highly effective solution.
What is PTAB and How Does it Work?
Percutaneous Transmural Arterial Bypass (PTAB) using the DETOUR™ System (Endologix) is an innovative, minimally invasive procedure that mimics the principles of open bypass while eliminating the need for large incisions.
Key Advantages of PTAB
✅ Minimally Invasive – No large surgical incisions, reducing recovery time
✅ Restores Blood Flow – Reroutes circulation around severe blockages
✅ Reduces Risk of Amputation – A life-changing alternative for high-risk patients
✅ Lower Periprocedural Morbidity – Less stress on the body compared to traditional surgery
Using a catheter-based technique, PTAB creates an extended femoral bypass, redirecting blood flow around long-segment blockages in the superficial femoral and popliteal arteries. This approach is particularly beneficial for patients who:
-
Have long-segment (≥ 20 cm) heavily calcified chronic total occlusions
-
Have failed previous endovascular treatments
-
Are not candidates for open femoropopliteal bypass surgery

"50% of patients in the U.S. that undergo an above- or below-the-knee amputation never receive a formal vascular evaluation."
