Lower-Limb Wound Care

Why do lower-limb wounds heal slowly?

Chronic lower-limb wounds are common in patients with diabetes, peripheral arterial disease, venous insufficiency, or prolonged bed rest. Poor circulation, impaired sensation, repeated pressure, and infection can all slow healing, and wounds may worsen without proper management.

Common types

• Diabetic foot ulcers
• Ischemic ulcers from poor arterial circulation
• Venous ulcers related to varicose veins
• Pressure injuries from prolonged bed rest or immobility

Evaluation and care approach

Wound care begins with identifying the underlying cause, including vascular assessment (arterial and venous ultrasound), infection control, debridement, and appropriate dressing selection. Systemic factors such as blood sugar control and nutrition are also addressed, with multidisciplinary coordination when needed.

When to seek care

If a wound has not improved within two weeks, or shows increasing redness, swelling, pain, discharge, or odor, prompt evaluation at a cardiovascular surgery or related clinic is recommended to avoid delayed treatment.
