compare between GLASS and WIFI Staging in predicting limb salvage in patients with chronic limb threatening ischemia ( CLTI) undergoing endovascular revascularization.
Peripheral arterial disease (PAD) is estimated to affect over 200 million people worldwide. These rates are expected to rise as increasing life expectancies continue to shift the population toward older age. At the most severe end of the disease spectrum, chronic limb-threatening ischemia (CLTI) affects 11% of patients with PAD and is associated with high rates of limb loss and mortality as well as high costs of care.(1) The Society for Vascular Surgery's WIfI (Wound, Ischemia, foot Infection) staging system was developed to classify threatened limbs using factors that affect amputation risk and clinical management in patients with chronic limb threatening ischemia . These include the extent of the wound, degree of ischemia, and severity of any foot infection. It has been validated as a predictor of limb salvage in peripheral artery disease.(2,3)
The Global Vascular guidelines 'GVG "proposes a new Global Anatomic Staging System (GLASS), which is a new method of quantifying the anatomic severity of infrainguinal disease in patients with chronic limb-threatening ischemia. But it has not been used for predicting limb salvage apart from use as a tool in deciding the mode of intervention for patients with chronic limb-threatening ischemia (CLTI).
