Ankle Brachial Index (ABI) for the Treated Limb	A measure of the fall in blood pressure in the arteries supplying the legs and is used to detect evidence of blockages in the peripheral vessels. It is calculated by dividing the higher systolic blood pressure in the ankle (dorsalis pedis or posterior tibial) of the one leg by the higher of the two systolic blood pressures in the arms. ABI=Highest Ankle Systolic Pressure/Highest Brachial Systolic Pressure. The ABI is the ratio of the ankle to arm pressure, and an ABI between 0.9 and 1.3 is considered normal. A reduced ABI (less than 0.9) is consistent with peripheral artery occlusive disease, with values below 0.8 indicating moderate disease and below 0.5 severe disease. A value greater than 1.3 is considered abnormal suggesting calcification of the walls of the arteries and noncompressible vessels, reflecting severe peripheral vascular disease. For patients in whom the ABI cannot be accurately measured , toe pressure measurement and toe brachial index should be used.	Pre-Procedure

Vascular Quality of Life (VascuQol) Total Scores	Vascular Quality of Life (VascuQol) : A standardized, validated questionnaire used to evaluate vascular disease-specific health outcomes. VascuQol total score includes scores of Activity Domain, Symptom Domain, Pain Domain, Emotional Domain and Social Domain. Each item is rated as a 7 point response scale, with a score of 1 being the worst and a score of 7 the best possible. The total average score is the sum of all 25 items scores divided by 25. For each separate domain an average score can be calculated (sum of all items of one domain divided by the number of items of that domain). The highest score for each domain is 7, which indicates best health outcome. There are no sub scales.	1 month
