Measure
Enrolled and Treated Patients
All patients enrolled in the DETOUR1 Clinical study to evaluate the PQ Bypass Detour System for Femoropopliteal Bypass to complete percutaneous fem-pop bypass. All patients were enrolled in the cath lab with a single procedure using the PQ Bypass Detour System, comprised of the PQ Crossing Device and the Torus Stent Graft System. Patients were followed to 24 months.

Enrolled and Treated Patients
n=78 participants at risk
All limbs enrolled in the DETOUR1 Study of the enrolled and treated patients. Some subjects had bilateral enrollment (the Detour Procedure was performed on both legs), because of this, the all-cause mortality rate has a different denominator than the other limb related adverse events. A total of 78 participants were enrolled (82 lesions), and one patient was enrolled but not treated due to technical failure of the device. The all-cause mortality denominators (at Risk values) are different from the other limb related adverse events. The all-cause mortality rate is reported at 1/77.
