In-Vivo Optical Spectroscopy (INVOS) as a Prognostic Tool for Peripheral Artery Disease During Endovascular Intervention: A Pilot Study

An INVOS/SBP ratio fold change greater than 1.25-fold is associated with improved outcomes following endovascular intervention for PAD. In-Vivo Optical Spectroscopy may serve as a valuable intraoperative prognostic tool, particularly in IC patients. Further studies are needed to validate these findings.Clinical ImpactThe clinical impact of the current work is to improve the knowledge in the application of INVOS measurements peri operative in clinical practices and improve patients care. Post operative surveillance with INVOS could be used to confirm surgical success. INVOS ratio lower than 1.25-fold after first revascularization should be reassessed and improve blood flow towards the limb. Although limited, this pilot study shows that the use of INVOS can be an adjuvanted tool in monitoring surgical outcomes in patients with PAD.
