From Angiosome to Woundosome: An Interdisciplinary Approach to Personalized Revascularization in Chronic...

Background/Objectives: Chronic limb-threatening ischemia (CLTI) is the most advanced stage of peripheral arterial disease and is associated with high rates of major amputation and mortality. The angiosome concept has become an important tool for planning targeted revascularization. However, its clinical value may be limited in patients with complex arterial disease, impaired collateral circulation, and microvascular dysfunction. This review explores the relationship between angiosome-guided revascularization and the emerging woundosome concept, which focuses on functional wound perfusion. Methods: A narrative review with a structured literature search was performed using PubMed/MEDLINE, Scopus, and Web of Science. Studies evaluating angiosome-guided revascularization, direct versus indirect revascularization, collateral circulation, pedal arch integrity, and perfusion-related outcomes in CLTI and diabetic foot disease were included. Results: Most observational studies and meta-analyses suggest that direct angiosome-targeted revascularization may improve wound healing and limb salvage in selected patients. However, clinical outcomes are also influenced by collateral circulation, anatomical variability, infra-malleolar perfusion, pedal arch integrity, and microvascular function. The woundosome concept expands the traditional angiosome model by emphasizing effective perfusion of the wound bed through direct arterial inflow, collateral pathways, and functional perfusion assessment. Conclusions: Combining the angiosome and woundosome concepts may provide a more practical and individualized approach to revascularization planning in CLTI by integrating anatomical vascular mapping with functional wound perfusion assessment.
