Intraoperative Simultaneous Pressure Guided Revascularization Study

Secondary analyses will examine the Ankle-Brachial Index, and the absolute limb pressures. In addition, the changes in flow rate of contrast before- and after- intervention will be examined as an indicator of perfusion.

A secondary analysis will examine the rate of contrast flow during pre-intervention and post-intervention angiograms, and correlate these findings with hemodynamic measurements recorded during surgery.
