•Diagnosis: Patients with an ABPI of 0.7 or above, but not exceeding 1.2 will be considered to have moderate peripheral vascular disease and will be included in the study. The presence of chronic venous hypertension will be on clinical examination and confirmed by Photoplethysmograhy (PPG).
•Patients who have had significant peripheral vascular disease and have had successful revascularisation with an ABPI of 0.7 or above.
•The ulcer size will be between more than 1 cm2 and not exceeding 100cms2.
