Study Details

Study Description

Brief Summary

The stent-FP study investigates the impact of coverage of profound femoral artery (PFA) by bare metal stent deployed in proximal superficial femoral artery (SFA) lesions. 300 patients with femoral bifurcation lesions will be included and divided into 3 groups according to the location of proximal stent edge. The primary endpoint of the study is major adverse events and freedom from target lesion revascularization at 48 months. Secondary endpoints include primary patency of PFA and bare metal stent at 1,6, 12,24,36and 48 month, MAE and F -TLR at 1,6, 12,24,36 month.

Arms and Interventions

Arm Intervention/Treatment
PFA slightly jailed by proximal SFA stent(100 pts)

Procedure: endovascular treatment
The bare metal stent covers the deep femoral artery lower than 50%

PFA moderately jailed by proximal SFA stent(100 pts)

Procedure: endovascular treatment
The bare metal stent covers the deep femoral artery in 50-90%

PFA totally jailed by proximal SFA stent (100pts)

Procedure: endovascular treatment
The bare metal stent totally covers the deep femoral artery

  3. F -TLR [post-interventional 1,6, 12,24,36 month]

    freedom from target lesion revascularization at 1,6, 12,24,36 month
