2D Perfusion DSA for the Quantification of Infrapopliteal Angioplasty
Ischemia Limb

About this trial
This is an interventional diagnostic trial for Ischemia Limb focused on measuring Infrapopliteal angioplasty, Tissue perfusion, Quantification
Eligibility Criteria
Inclusion Criteria:
- Patients prescheduled for infrapopliteal angioplasty due to chronic limb-threatening ischemia.
- Written informed consent obtained
Exclusion Criteria:
- Image post-processing not feasible due to significant motion artifacts produced during DSA
Sites / Locations
- Patras University Hospital

Experimental
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.
