NCT05570019

Brief Summary

In this prospective single-center observational study, arterial perfusion in patients with lower limb peripheral arterial disease will be assessed with standard diagnostic tools (toe pressure, trans-cutaneous oxygen pressure, ankle-brachial index and fluorescence angiography) before and after standard revascularization procedures (open surgery and/or angioplasty).

Outcome Measures

Primary Outcomes (1)

  • Transcutaneous oxygen pressure

    Change in transcutaneous oxygen pressure is measured before and after the revascularization procedure.

    Pre-procedural, post-procedural (within 5 days) and 3 months after the index procedure

Secondary Outcomes (8)

  • WIfI stage

    Pre-procedural, post-procedural (within 5 days) and 3 months after the index procedure

  • Rutherford category

    Pre-procedural, post-procedural (within 5 days) and 3 months after the index procedure

  • Primary patency

    Post-procedural (within 5 days) and 3 months after the index procedure

  • Secondary patency

    Post-procedural (within 5 days) and 3 months after the index procedure

  • Limb salvage

    Post-procedural (within 5 days) and 3 months after the index procedure

  • +3 more secondary outcomes

Interventions

Open surgery (arterial endarterectomy with or without bypass surgery) and/or angioplasty (with or without stent placement)
