NCT03085524

Brief Summary

The presence of foot symptoms at rest or tissue necrosis in patients with peripheral artery disease is a medical urgency and represents a state of critical limb ischemia (CLI) where the risk of amputation, in the absence of revascularization, is high. No trial conducted to date in peripheral revascularization has determined the effect of diabetes on mechanism of revascularization failure. Therefore, this trial represents a unique opportunity to investigate the mechanisms by which diabetes affects surgical and endovascular revascularization procedures with the long-term goal of improving outcomes in CLI.

Outcome Measures

Primary Outcomes (2)

  • Major Adverse Limb Event - free survival

    The combination of amputation, surgical revascularization, thrombectomy, thrombosis, interposition graft, or death

    1 year

  • Restenosis

Study Population

This ancillary study is an observational study design examining the effects of diabetes mellitus on restenosis following surgical or endovascular revascularization in CLI patients. Eligible patients will be screened according to the specified exclusion and inclusion criteria of the BEST-CLI trial.

You may qualify if:

  • Male or female, age 35 years or older
  • Atherosclerotic, infrainguinal PAD
  • CLI, defined as arterial insufficiency with gangrene, non-healing ischemic ulcer, or rest pain, consistent with Rutherford classes 4-6
  • Candidate for either open or endovascular infrainguinal revascularization as judged by the treating investigators
  • Adequate inflow into the index femoral artery
  • Adequate popliteal, tibial, or pedal revascularization target
  • Willing to comply with protocol, attend follow-up appointments, complete all study assessments, and provide informed consent
  • Endovascular revascularization with a stent
  • Surgical revascularization with a vein graft-

You may not qualify if:

  • Femoropopliteal disease pattern consistent with TASC IIA
  • Complete occlusion of the iliac artery
  • Aortoiliac occlusive disease or severe common femoral artery disease
  • Presence of a femoral, popliteal or tibial aneurysm of the index limb
  • Life expectancy less than 2 years
  • Deemed excessive risk for surgical bypass
  • A vascular disease prognosis that includes an anticipated above ankle amputation on index limb within 4 weeks of index procedure
  • Renal dysfunction defined as MDRD eGFR ≤ 30ml/min/173 m2 at the time of screening
  • Currently on dialysis or history of a renal transplant
  • A documented hypercoagulable state
  • Nonatherosclerotic occlusive disease
  • Any prior infrainguinal revascularization
  • Current immuno-suppressive medication, chemotherapy or radiation therapy
  • Absolute contraindication to iodinated contrast

Data Sharing

IPD Sharing
Will not share

The proposed research will include data from approximately 500 subjects enrolled in the BEST-CLI clinical trial. The final dataset will include self-reported demographic, ultrasonographic, and laboratory data from the subjects. The investigators will be collecting identifying information, but the final dataset will be stripped of identifiers prior to release for sharing. Thus, the investigators will make the data and associated documentation available to users only under a data-sharing agreement that provides for: (1) a commitment to using the data only for research purposes and not to identify any individual participant; (2) a commitment to securing the data using appropriate computer technology; and (3) a commitment to destroying or returning the data after analyses are completed.
