Executive summary

  • Do not start high compression blindly: first assess arterial supply (palpable pulses and formal vascular assessment where indicated).
  • Compression is the cornerstone for venous ulcers when arterial disease is not significant; it improves healing and reduces recurrence.
  • Wound care: choose dressings to manage exudate; avoid routine topical antibiotics/antiseptics unless infected and following guidance.
  • Dermatitis/pain: treat stasis eczema, address pain, and ensure appropriate analgesia + skin care.
  • Refer early if diagnostic uncertainty, suspected arterial/mixed disease, non-healing, large/complex ulcers, or recurrent ulcers.

Assessment (rapid checklist)

  • Ulcer history: duration, recurrence, prior DVT/varicose veins, mobility, pain pattern, exudate/odour, dressings used.
  • Examination: location (gaiter area typical), oedema, varicosities, lipodermatosclerosis, atrophie blanche, dermatitis.
  • Vascular screen: pulses, capillary refill, temperature, features of arterial insufficiency (rest pain, pallor, cool foot).
  • Infection: increasing pain, erythema, warmth, swelling, malodour, systemic features (if infected follow NICE antimicrobial guidance for leg ulcer infection).

Management principles

  • Compression therapy: initiate/optimise via community nursing/tissue viability services once arterial disease has been excluded/assessed.
  • Dressings: pick for exudate management and comfort; avoid over-complexity unless specialist advice.
  • Skin care: emollients; treat venous eczema (topical steroid of appropriate potency short-term if inflamed).
  • Prevention: long-term compression hosiery after healing to reduce recurrence; address venous reflux/varicose veins where appropriate.

FAQs

Should I give antibiotics “because it looks nasty”?
Not routinely. Treat only if clinically infected (local spreading erythema, increased pain, warmth, swelling, systemic features). Follow NG152 for antimicrobial choices.
Do I need Doppler/ABPI in everyone?
You need an assessment of arterial supply before strong compression. If pulses are reduced, symptoms suggest arterial disease, or there is any uncertainty, arrange formal vascular assessment through local pathways.
When should I refer?
If you suspect arterial/mixed disease, the ulcer is not improving, it is large/complex, recurrent, or there are red flags (rapid deterioration, suspected malignancy, significant pain out of proportion, systemic infection).
