Acronym:
EchoPIV in SFA
Brief Summary:
Peripheral arterial disease PAD in the lower extremity is the third leading cause of atherosclerotic cardiovascular morbidity Endovascular treatment has become the principal surgical strategy in femoro-popliteal lesions Stent placement induces significant changes in the arterial geometry and thereby in the hemodynamic environment Visualization of local blood flow patterns around stents is challenging but clinically relevant Blood flow has a significant influence on the development of atherosclerosis and therefore stent patency In vivo blood flow characterization might enable the recognition prediction and explanation of in-stent restenosis This study will therefore aim to investigate the feasibility of a novel ultrasound technique echoPIV to quantify spatiotemporal blood flow near stented femoral artery lesions Furthermore the blood flow information obtained during the echoPIV measurements will be used as patient-specific boundary conditions in a computational fluid dynamics CFD simulation The tested hypothesis is that blood flow quantification using echoPIV is feasible in and around stents in the femoral artery and that it will improve CFD simulations
