This study aims to assess the role of infrapopliteal angioplasty (PTA) as an important tool for limb salvage in patients with critical limb ischemiaInfrapopliteal angioplasty has been increasingly applied to patients with critical limb ischaemia (ischemic rest pain, ulcers, &/or gangrene) Patients with CLI are typically elderly with multiple co-morbidities and the typical pattern of disease includes multiple stenoses and occlusions in the arterial tree from the superficial femoral artery (SFA) to the pedal arch. However, in 25% of patients with CLI, the lesions are Confined to the infrapopliteal arterial territory.
