Why Leg Wounds That Won’t Heal May Point to Vascular Disease

A small sore on your ankle, shin, toe, or foot should usually start improving with basic care. When it lingers, reopens, drains, darkens, or becomes more painful, the problem may run deeper than the skin. Non-healing leg wounds can sometimes point to vascular disease, especially when blood flow, vein pressure, or poor circulation interferes with normal healing.

How Can Vascular Disease Affect Wound Healing?

Your body needs steady circulation to repair damaged tissue. Arteries carry oxygen-rich blood to your legs and feet. Veins help move blood back toward the heart. When either side of that system isn’t working well, healing can slow down.

Peripheral artery disease, or PAD, can limit blood flow to the lower legs and feet. The Society for Vascular Surgery lists foot sores that won’t heal as a possible PAD symptom. Venous insufficiency works differently. When leg veins don’t move blood back efficiently, pressure can build in the lower legs and contribute to swelling, skin changes, and hard-to-treat ulcers.

Why You Shouldn’t Guess at the Cause

A non-healing wound can have more than one cause. Infection, diabetes, pressure injuries, venous insufficiency, PAD, and other health issues can all affect healing. In some cases, more than one factor may be involved.

Guessing can be risky. For example, compression may help certain vein problems, but it may not be appropriate if arterial blood flow is severely reduced. A vascular evaluation can help clarify whether circulation is part of the problem before treatment decisions are made.

Vascular Evaluation in New York City

At his New York City vascular surgery practice, Dr. Alan Benvenisty, MD, evaluates circulation problems that may affect wound healing, including venous insufficiency, PAD, and other vascular conditions. As a board-certified vascular surgeon, Dr. Benvenisty can assess symptoms, review risk factors, and determine whether blood-flow testing may be needed.

Treatment depends on the cause. Care may involve wound care coordination, compression when appropriate, medication, minimally invasive vascular procedures, or surgery for advanced arterial disease.

FAQs About Non-Healing Leg Wounds

Can poor circulation cause leg wounds that won’t heal?

Yes. Poor circulation can make it harder for tissue to get the oxygen and nutrients needed for repair. Artery problems and vein problems may both contribute to non-healing leg wounds.

Are venous ulcers the same as diabetic foot ulcers?

No. Venous ulcers are usually linked to venous pressure and poor blood return, often near the lower leg or ankle. NIH’s StatPearls describes venous leg ulcers as late indicators of chronic venous insufficiency and venous hypertension. Diabetic foot ulcers are often related to nerve damage, pressure, infection risk, and circulation problems.

When should I see a vascular surgeon for a leg wound?

Consider vascular evaluation if a wound doesn’t improve, keeps reopening, appears with swelling or skin discoloration, or affects the foot or toes. Rest pain, coldness, numbness, or dark color changes should be addressed promptly.

Can venous insufficiency get worse over time?

It can. Chronic venous insufficiency may progress from swelling and heaviness to skin changes or ulcers in some patients. Early evaluation can help identify the problem before skin damage becomes harder to manage.
