Outcome Measures

Primary Outcomes (2)

  • Number of Patients With Primary Patency at 12 Months Post-procedure

    Primary patency is defined as hemodynamic evidence of blood flow through an open graft that has maintained uninterrupted patency and has not previously undergone a revision to restore blood flow.

    12 months

  • Major Adverse Event Occurrences Through One Month Post-procedure

    The number of Major Adverse Event occurrences through one month post-procedure. A major adverse event requires significant therapy, including unplanned increase in the level of care, permanent sequelae, hospitalization, or death. This outcome measure presents the number of Major Adverse Event occurrences (i.e. - one patient could have multiple occurrences), and differs from the Serious Adverse Events reporting measure, which presents the number of patients that have been affected by a Serious Adverse Event.

    one month post-index procedure

Secondary Outcomes (23)

Eligibility Criteria

Age21 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patient requires below-knee bypass secondary to severe claudication, rest pain or tissue loss due to peripheral arterial occlusive disease.
  • Patient meets the disadvantaged autologous vein criteria described in Section 4.1.
  • Patient has a post-operative life expectancy greater than one year.
  • Patient is at least 21 years of age.
  • Patient is able to comply with all study requirements and be available for follow-up visits at 1, 6, 12, 24 and 36-months post-procedure.
  • Patient is willing and able to provide written, informed consent.

You may not qualify if:

  • Patient has had a previous instance of Heparin Induced Thrombocytopenia type 2 (HIT-2) or has known hypersensitivity to heparin.
  • Patient requires an infragenicular bypass for reasons other than peripheral arterial occlusive disease.
  • Patient requires sequential extremity revascularizations or other procedures that require use of additional vascular grafts.
  • Patient is in need of, or is scheduled for, a cardiac surgical procedure or a different vascular surgical procedure within 30 days of study procedure. However, inflow procedures that facilitate the bypass are permitted, as long as they are not performed at the same sitting as the bypass procedure.
  • Patient has been previously randomized for this study.
  • Patient has active infection in the region of graft placement.

Limitations and Caveats

The study was terminated prior to completion of enrollment. The primary patency and secondary endpoints were not calculated due to the paucity of data.
