Abstract
Introduction
Lower Extremity Extracorporeal Distal Revascularization (LEEDR) is a novel, preclinically tested technique designed to provide temporary limb perfusion in cases of acute limb ischemia when immediate revascularization is not feasible.
Methods
LEEDR employs an extracorporeal pump and circuit to draw arterial blood from a proximal inflow site and deliver it to an outflow artery within the ischemic limb. The system is designed for bedside initiation using percutaneous access.
Results
ALI from embolism, thrombosis, or trauma rapidly leads to irreversible tissue damage. Delays in revascularization are associated with high rates of limb loss and systemic complications. LEEDR offers a time-sensitive intervention aimed at mitigating these risks and preserving limb viability until definitive treatment is available.
Conclusion
LEEDR is a promising temporary perfusion strategy for limb salvage in ALI. This manuscript outlines its procedural components, technical considerations, and anticipated role in bridging patients to definitive revascularization.
