Ischemic Foot Ulcers: Is Intervention Better Than Wound Care Alone

You are being asked to take part in this study because your doctor has determined that you have an ischemic foot ulcer. This research study will compare two approved standard of care treatment modalities for the management of ischemic foot ulcers. The ischemic foot ulcer (wound) on your foot is a result of a blocked artery in your leg. The wound can sometimes be healed with wound care alone, which includes dressing changes with creams and removing (debriding) the dead tissue. Alternatively, the significant narrowing or blockage in one of the arteries in your leg can be treated with several endovascular treatment techniques including: * angioplasty, also called percutaneous transluminal angioplasty (PTA) and/or * stent placement * atherectomy The hypothesis of this study is that early endovascular or surgical intervention in subjects with moderate arterial insufficiency and a non-healing foot ulcer results in a higher overall incidence of wound healing in a significantly shorter period of time.
