Objective: To evaluate immediate results, clinical improvement, long-term patency and predictive factors of long-term outcome after superficial femoral artery percutaneous angioplasty.
Patients and methods: Restrospective monocentric study of 101 patients (142 lesions: 105 stenoses and 37 occlusions) technical results, long-term patency (19 months), and clinical improvement (27,5 months) were analyzed. A multifactorial analysis was performed.
Results: Technical success was obtained in 99%, complications and mortality rates were respectively 3% and 2%. At the end of follow-up, 55 patients were clinically improved (20 lost to follow-up), and femoral artery remained patent in 62 patients (10 to follow-up). Statistical analyses revealed 8 significant predictive factors of a good outcome (P<0.05): female gender, non-diabetic, at least one patent artery below the knee, AHA classification <2, no stent, treatment of an occlusion, number of dilatations<3, treatment by statins for hypercholesterolemia.
Conclusion: Femoral superficial artery angioplasty is usually achieved with low complication rate. We found eight factors predictive of long-term outcome, to keep in mind when indications are discussed.
