Study type | Observational |
Endovascular treatment with stenting is currently used in the treatment of femoro-popliteal lesions. This technique tends to extend to lesions for which the gold standard remains until now the open surgery treatment (lesions TASC C and D). The primary objective of the study was to evaluate the clinical efficacy at 12 months of the SuperA stent (Abbott) in the treatment of long de novo atherosclerotic lesions TASC C and D in patients with symptomatic peripheral arterial disease. The secondary objectives are to evaluate the clinical effectiveness of the SuperA stent at 24 months, according to clinical, morphological and haemodynamic criteria, the possible influence of calcifications and the quality of life of patients. The SuperA stent treatment is not specifically provided for by the Protocol but is carried out within the framework of the care. This study is an observationnal study.
