A wound on the foot or toe that does not heal can be concerning and may indicate an underlying circulation condition. One of the most serious causes of non-healing wounds is Critical Limb Ischemia (CLI), an advanced stage of Peripheral Artery Disease.
Healthy circulation delivers oxygen and nutrients necessary for tissue repair. Reduced circulation may result in wounds that remain open for weeks or months, ulcers on toes or feet, skin discoloration, increased sensitivity, or delayed healing.
Symptoms of CLI may include persistent foot pain at rest, non-healing wounds on toes or feet, skin discoloration, cool temperature in the foot, thickened toenails, and reduced sensation.
Limb salvage focuses on improving blood flow to support healing and reduce complications.
Treatment options may include angioplasty, stenting, plaque removal procedures, and comprehensive circulation evaluation.
Signs that indicate need for evaluation include wound not healing after several weeks, persistent pain in foot or toes, darkened skin around wound, history of diabetes or smoking, and decreased sensation in feet.
Vascular Institute of Chattanooga provides advanced vascular evaluation and minimally invasive treatment options designed to improve circulation and support healing.
