Peripheral Vascular Diseases Clinical Trial
Official title:
Randomized Trial of Stenting After Dilation With or Without Paclitaxel Eluting Balloon or Atherectomy in Patients With Symptomatic Peripheral Artery Disease
The purpose of the study is to evaluate the efficacy of stenting after dilation with or without paclitaxel-eluting balloon or atherectomy in patients with symptomatic peripheral artery disease.
The superficial femoral artery is a common place for arteriosclerosis in patients
symptomatic for lower extremity vascular disease. Advances in percutaneous transluminal
angioplasty (PTA) and stenting have provided new options for the treatment of the disease in
this arterial segment. Despite the initial technical success rate of more than 95% the late
clinical failure remains an important concern.
Restenosis after PTA occurs in 40-60% within one year. Percutaneous removal of the
obstructive material through atherectomy may reduce restenosis rate. So far, data in support
of excisional atherectomy derive from registries. Another attempt to reduce restenosis is
the use of paclitaxel eluting balloons (PEB). First clinical studies suggest that the use of
PEBs during percutaneous treatment of femoropopliteal disease is associated with significant
reductions in late lumen loss and target-lesion revascularization.
There is no randomized comparison of this three different interventional strategies. Thus
the aim of this study is to evaluate the efficacy of these strategies in terms or reduction
of diameter stenosis at follow-up angiogram.
