Percutaneous Transmural Arterial Bypass | MedStar Health

Minimally invasive treatment to the superficial femoral artery

People who have long, and complex obstructive disease of the superficial femoral artery (SFA) have limited success with traditional endovascular procedures and face a prolonged recovery and the risk of complications when undergoing the surgical bypass procedure.

The Percutaneous Transmural Arterial Bypass (PTAB) procedure combines the benefits of the surgical bypass and endovascular approach. During this procedure, a vascular surgeon and interventional cardiologist detour around a long, calcified blockage of the SFA by percutaneously creating a channel through the adjacent femoral vein. A stent is inserted from the top of the SFA, into the femoral vein, and back into the popliteal artery which allows increased blood flow to the leg.



Claudication is muscle pain caused by clogged arteries that reduce blood flow to the muscles.


Computerized Tomography (CT) Scan

The cardiac computed tomography scan, or cardiac CT, uses X-rays to create three-dimensional images of your heart and blood vessels.


A fluoroscopy is an imaging technique that uses a continuous X-ray beam passed through the body to create real-time, moving images of your internal structures.

Magnetic Resonance Imaging (MRI)

Magnetic resonance imaging, better known as cardiac MRI, is a combination of radio waves, magnets and computer technology to create images of your heart and blood vessels.
