‘Real Angiosome’ Assessment from Peripheral Tissue Perfusion Using Tissue Oxygen Saturation Foot-mapping in Patients with Critical Limb Ischemia

Objectives The “tissue oxygen saturation (StO2 ) foot-mapping” method was developed using a non-invasive near-infrared tissue oximeter monitor to classify the foot regions as ischemic and non-ischemic areas. The purpose of this study was to evaluate StO2 foot-mapping as a reliable method to detect i...

Description
Summary:Objectives The “tissue oxygen saturation (StO2 ) foot-mapping” method was developed using a non-invasive near-infrared tissue oximeter monitor to classify the foot regions as ischemic and non-ischemic areas. The purpose of this study was to evaluate StO2 foot-mapping as a reliable method to detect ischemic areas in the feet of patients with critical limb ischemia (CLI), and to compare the results with assessments from the angiosome model. Methods The foot areas of 20 CLI patients and 20 healthy controls were classified into four regions: (1) 0 ≤ StO2
