- Accepts Healthy Volunteers
- No
Inclusion Criteria
- •Chronic Limb-Threatening Ischemia as defined by presence of Peripheral Artery Disease (PAD) in combination with rest pain, gangrene, or a lower limb ulceration>2 weeks duration (ref Global Guidelines)
- •Atherosclerotic infra-popliteal PAD
- •Adequate distal anastomotic target (crural, tibial or popliteal below the knee with one single run-off) between knee and ankle distal to the stenotic/occluded segment.
- •Available autogenous vein conduit based on preoperative vein mapping.
- •Understand the nature of the procedure and willingness to comply with protocol. Attend follow-up appointments and provide written informed consent.
Exclusion Criteria
- •Bypass with artificial conduit or cryopreserved allografts
- •Bypass for non-atherosclerotic lesions
- •Life-expectancy less than 2 years
- •Any psychological, developmental, physical or emotional disorder that the investigator believes would interfere with surgery or follow-up.
- •Any condition that the investigator believes should exclude participation.
- •Excessive risk for adverse events during open surgery as judged by the investigator.
