Perfusion
Consecutive patients scheduled to undergo infrapopliteal angioplasty or stenting, or both, as part of their standard treatment for Rutherford-Becker class 5 and 6 chronic limb-threatening ischemia, were included in the study. All procedures were performed using local anesthesia. An antegrade access was used in all patients followed by the deployment of a 5 or 6 Fr arterial sheaths. A semi-lateral foot projection was preferred and the pre-revascularization DSA of the foot was performed via a 5 Fr angiographic catheter placed at the distal third of the popliteal artery. Following revascularization of one or more tibial arteries, the catheter was placed at the same popliteal segment and post-procedural DSA of the foot was performed following the exact pre-revascularization injection protocol at the same semi-lateral projection. The 2D-perfusion imaging and analysis of the DICOM files was performed after revascularization.
2D perfusion digital subtraction angiography of the foot.
2D perfusion digital subtraction angiography of the foot was performed after infrapopliteal angioplasty and Perfusion Blood Volume (PBV), Mean Transit Time (MTT), and Perfusion Blood Flow (PBF) maps were extracted by analyzing Time-Intensity Curves and signal intensity on the perfused vessel mask.
