Sensors that implement laser speckle image streaming provide real-time, noninvasive assessment of peripheral blood flow during endovascular revascularization.This single-center feasibility study evaluated a laser speckle-based peripheral blood flow Exercise ball monitoring system in 24 patients with peripheral arterial disease.System-quantified blood flow values showed improvement at the conclusion of the procedure in 20 of 24 patients (83.

3%).Of the four patients without improved flow values, waveform morphology improved in three.Waveforms Horn Bags graded as moderate to severe peripheral arterial disease decreased from 71% before the procedure to 25% after the procedure, with improvement in 19 of 24 patients.

In this limited population, laser speckle imaging could offer a highly sensitive method of detecting intraprocedural pedal blood flow changes.
