Withdrawn study sought to predict which legs could be saved
NCT ID NCT06014242
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study was designed to see if measuring blood flow resistance in tiny leg vessels could predict whether a limb could be saved after artery-opening procedures in people with critical limb ischemia. It planned to enroll patients with severe leg artery disease and use a special measurement technique during angiography. However, the study was withdrawn before any participants were enrolled, so no results are available.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Chronic critical limb ischemia (Rutherford 4-6). * Age ≥18 years * Ability and willingness to sign the IRB approved Informed Consent form Exclusion Criteria: * Non-reconstructable chronic total occlusive disease of the proximal inflow vessels that would make flow reserve measurements impossible. * Non-salvageable lower extremity due to infection or overwhelming per-existing tissue loss (most critical Rutherford 6 patients). * Inability to understand the study or a history of non-compliance with medical advice; * History of any cognitive or mental health status that would interfere with study participation; * Currently enrolled in any pre-approval investigational study. * Female subjects who are pregnant or nursing or planning to become pregnant within the study period; * Known sensitivity to contrast media, which can't be adequately pre-medicated; * Expected life span less than 6 months. * Unable to read/understand/sign the English Language consent form
