Detailed Description:

This will be a nonrandomized, nonblinded, prospective observational study to correlate the results obtained with the traditional measures of success of endovascular revascularization of peripheral arteries for the treatment of chronic limb ischemia; i.e., ABPI, PVR with oxyhemoglobin (OxyHb) and deoxyhemoglobin (DeoxyHb) measurements obtained with a new imaging device manufactured by HyperMed Inc (OxyVu) that uses hyperspectral technology.


Ages Eligible for Study:   50 Years to 85 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

Patients who have chronic limb ischemia and present with the symptoms of claudication, rest pain or having minor non-healing ulcers or gangrene (Rutherford category 1 to 6) who also require percutaneous endovascular revascularization.


Inclusion Criteria:

  1. Patients with established diagnosis of lower limb ischemic based on their symptoms of claudication, rest pain, non-healing ulcers or gangrene and other vascular laboratory tests that are currently used to make this diagnosis and have been scheduled for endovascular revascularization.
  2. Age group between 50-85
  3. Gender - Male or Female
  4. Race - all race and ethnicities

Exclusion Criteria:

  1. Patients with known cardiac disease - new MI (within 3 months).
  2. Patients with hypertension with the systolic BP >200 or diastolic BP>110 on the day of testing
  3. Patients on supplemental O2 for chronic obstructive lung disease
  4. Bed-ridden subjects - either due to chronic disability or neurological problems
