This study is a comparison of two different ways to treat blockage in the artery of the
thigh. The first is an older way with incisions in the groin and just above the knee. A
plastic tube is then inserted to make a bypass from the groin to the knee. The second
treatment offered is through a needle hole in the groin. A thin plastic tube covering a
metal stent is inserted into the artery and released to bypass the blockage from inside the
artery. No incisions are needed. Patients are enrolled and then selected for one treatment
method or another by chance. The patients will be followed for two years to see how the two
different treatment methods work compared to each other.
Inclusion Criteria:Patients that had atherosclerotic stenotic or occlusive lesions of the

to be acceptable surgical candidates in the event they were randomized to the surgical
Exclusion Criteria:Non-operative candidate,Contraindication to IV contrast use, Planned
