Mean Pressure Gradient and Fractional Flow Reserve at A Superficial Femoral Artery Dissection after Drug-Coated Balloon Angioplasty.

This is the first report of hemodynamics at a SFA dissection. The results suggest that low-grade dissection (types A or B) does not affect MPG and FFR at a SFA lesion. This indicates that a bailout stent may be unnecessary for patients with dissection of types A or B. A further investigation is needed to determine whether a scaffold is required for a SFA lesion with type C dissection.
