Effects of Remote Ischemic Preconditioning on Restenosis Post Lower Limb Revascularization Angioplasty

The investigators will established relation between restenosis and inflammatory response to shearing stress caused by angioplasty suggest that any mechanism that affect inflammatory response can consequently affect the restenosis rate. There is accumulated evidence that remote ischemic precondition has modifying suppressive effect on inflammatory response and the investigators hypothesized that RIPC may lead to reduction in post angioplasty restenosis rate.
