简要总结
Lower extremity peripheral artery disease (PAD) is a major health problem leading to significant morbidity and even mortality. Patients with superficial femoral artery stenosis make up an important proportion of patients with PAD, and since this type of involvement was reported to be most commonly associated with intermittent claudication, this patient population has been subject to intensive research on methods to prevent disease progression and further complications.
Endovascular treatment has become the first-line treatment for low-complexity femoropopliteal (FP) lesions classified as TASC (Trans Atlantic Inter-Societal Consensus) A and B. Conversely, in case of more extensive lesions (TASC C), this treatment is still under debate because of a primary permeability that is difficult to maintain over time. Recently, studies have shown the interest of drug eluting technologies in the treatment of TASC A & B femoral-popliteal lesions, by significantly improving patency rates compared to uncoated balloons or stents.
In this context, the endovascular treatment of FP complex lesions (TASC C) continues to develop widely.
During endovascular treatment, the quality of the artery preparation has recently been identified as a factor improving outcomes. The dilatation of the artery with an uncoated balloon or POBA (Plain Old Balloon Angioplasty) is the reference method performed before stent placement or drug-coated balloons. However, some new alternatives to prepare the artery have emerged, using no more dilatation but atherectomy (Jetstream™ system).
Atherectomy appears to reduce the risk of dissections and bailout stenting and improve the acute procedural results. Its long term outcome, when associated with drug coated balloons (DCB), has recently been demonstrated in the USA to be superior to angioplasty in a single center study JET-SCE.
The purpose of this study is to evaluate the efficacy and the feasibility of atherectomy, using the Jetstream™ artery preparation associated to DCB treatment (Ranger™ Paclitaxel-Coated balloon), in symptomatic patients with claudication (Rutherford 2 and 3) and with complex de novo FP arterial lesions (TASC C).
