What this trial studies

This observational study aims to assess the early safety and effectiveness of a novel procedure called percutaneous deep foot venous arterialization in patients with 'no-option' chronic limb-threatening ischemia (CLTI). The study will enroll patients who have previously undergone unsuccessful revascularization attempts and are at high risk for amputation. By utilizing the venous plexus of the foot as an alternative conduit for arterial flow, the study seeks to provide a potential solution for those with critical lower limb ischemia. Data will be collected on enrolled patients' demographics and medical history to evaluate outcomes.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with non-revascularizable critical limb ischemia and active trophic lesions.

Not a fit: Patients with revascularizable critical ischemia or those unable to comply with follow-up may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the risk of amputation and improve limb salvage in patients with no other treatment options.

How similar studies have performed: While this approach is innovative, existing literature indicates that similar techniques have shown promise, but this specific application is less commonly tested.
