Details and patient eligibility

About

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.

Inclusion criteria

Patients with chronic atherosclerosis obliterans aged over 18 years
Patients presenting Rutherford classification from 2-5
Patients is willing to follow-up on time
Patient has a life expectancy of at least 24 months
Prior to enrolment, the guidewire has crossed target lesion
De novo lesions located in the femoral artery bifurcation (5mm between distal CFA and proximal SFA), need for primary bare metal stent implantation
There is a patent deep femoral artery demonstrated by angiography
If the first-time endovascular treatment is failure, patients undergo endovascular treatment successfully at the second time, the patients can still be enrolled （9）For patients with aortoiliac artery lesions, they can be enrolled after the successful reconstruction of aortoiliac artery .

(10) The lower extremity artery needs to have a healthy runoff of no less than 10 cm above the ankle, and at least one healthy dorsalis pedis artery, medial or lateral plantar artery connected with the digital artery below the ankle (11) Informed consent signed by patients
