Best Treatment for Leg Ulcers — A Vascular Surgeon's Guide
Most non-healing leg ulcers are caused by a treatable vein or artery problem. Here's how modern vascular care closes wounds that dressings alone never could.
A leg ulcer is an open wound on the lower limb that fails to heal within 4–6 weeks. Without addressing the underlying cause, dressings and antibiotics rarely succeed. The good news: more than 90% of leg ulcers heal once the vascular driver is identified and corrected.
The three main types of leg ulcer
- Venous ulcers (≈70%) — shallow, weepy ulcers above the ankle, caused by long-standing varicose veins or deep vein damage.
- Arterial ulcers — painful, punched-out wounds on the toes, heel or shin from poor arterial supply (PAD).
- Diabetic neuropathic ulcers — painless ulcers on pressure points of the foot in people with diabetes.
Step 1 — Find the cause
Every non-healing ulcer deserves a duplex ultrasound of the veins and arteries, an ABI measurement, and a basic blood panel including HbA1c. Imaging tells us whether the wound is venous, arterial, mixed or diabetic-neuropathic — and that decides the entire treatment plan.
Step 2 — Treat the vascular driver
- Venous ulcers — EVLA, RFA or glue ablation of the leaking vein + multilayer compression bandaging.
- Arterial ulcers — angioplasty or bypass to restore in-line flow to the foot before the wound can heal.
- Diabetic ulcers — combined revascularisation, sharp debridement, offloading footwear and tight glycaemic control.
Step 3 — Modern wound therapy
Once blood flow is restored, advanced dressings, negative-pressure wound therapy (VAC), skin grafting and growth-factor application accelerate healing dramatically. Most venous ulcers close within 12 weeks of vein treatment; revascularised diabetic ulcers within 8–10 weeks.
Preventing recurrence
Lifetime compression stockings for venous disease, daily foot inspection in diabetes, smoking cessation, and an annual vascular review keep ulcers from coming back. If your wound hasn't healed in six weeks, see a vascular surgeon — every additional month of delay reduces the chance of complete healing.
