Summary

This study looks at whether using special tools to measure blood flow and take ultrasound images during leg bypass surgery can help predict how well the graft will work over time. It involves 450 people with severe leg artery disease who are having a vein bypass below the knee. The goal is to see if these checks can spot problems early and improve long-term outcomes.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

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.
