Evaluation of Perfusion and Oxygenation in Muscle of Patients With PAD Undergoing LER

October 16, 2024 updated by: Medical University of Graz

During this IIT, the MSOT (Multispectral Optoacoustic Tomography ) Acuity Echo will be used to scan participants with Peripheral Arterial Disease assess MSOT Multispectral Optoacoustic Tomography (single-wavelength and hemoglobin-related parameters) in the Tibialis Anterior, and flexor hallucis brevis, at multiple time-points before, during and after interventional Lower Extremity Revascularization (LER ).

Primary aim of the study ist the Comparison of the difference between oxygenated, deoxygenated hemoglobin and oxygenation in the tibialis anterior, and flexor hallucis brevis, at multiple time-points before, during and after interventional Lower Extremity Revascularization.
