tissue loss
Ulceration, gangrene, or non-healing wounds indicating severe ischemia and advanced peripheral arterial disease requiring urgent intervention.
Full Definition
Tissue loss represents the most severe manifestation of peripheral arterial disease, characterized by ulceration, gangrene, or non-healing wounds resulting from inadequate tissue perfusion. This finding indicates chronic limb-threatening ischemia and typically necessitates urgent revascularization or amputation to prevent progression and systemic complications. Tissue loss may present as dry gangrene (mummified tissue), wet gangrene (infected necrotic tissue), or ischemic ulcerations that fail to heal despite optimal wound care. The presence and extent of tissue loss significantly influence treatment urgency, procedural approach, and ultimate functional outcome in patients with peripheral arterial disease.
Usage
Usage note: Specify type (dry/wet gangrene, ulceration) and anatomical extent in documentation.
