Derm: Venous Ulcer: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – Venous Ulcer🎧 A high-yield breakdown of this common leg ulcer – caused by venous hypertension, key for MSRA and clinical practice.🧠 Key Learning Points📌 Definition• Venous ulcers are chronic, shallow wounds that develop due to poor venous return and increased venous pressure in the lower limbs, especially around the medial malleolus.📌 Causes & Risk Factors• Chronic venous insufficiency• Varicose veins• Deep vein thrombosis (DVT)• Prolonged standing/sitting• Obesity• Older age• Leg injury or trauma• Pregnancy• Family history💡 Mnemonic: VOLD-FLIPVaricose veins, Obesity, Long-standing/sitting, DVT, Family history, Low calf pump, Impaired mobility, Pregnancy📌 Pathophysiology• Incompetent venous valves → retrograde flow → chronic venous hypertension• Capillary leakage of fibrinogen → fibrin cuffing• Impaired oxygen diffusion → tissue hypoxia• Inflammation + poor healing → skin breakdown → ulcer📌 Symptoms• Shallow, irregular ulcers (typically gaiter region)• Mild discomfort or painless ulcer• Surrounding signs: haemosiderin pigmentation, venous eczema, atrophie blanche, oedema, lipodermatosclerosis• Often bilateral or recurrent📌 Differential Diagnosis• Arterial ulcer – painful, punched-out, weak pulses• Neuropathic ulcer – painless, plantar foot• Pressure ulcer – over bony prominences• Malignancy (Marjolin’s ulcer) – non-healing, rolled edges• Vasculitis or RA-related ulcers📌 Diagnosis• Clinical – typical site + surrounding signs• Must assess ABPI (Ankle-Brachial Pressure Index)<0.8: contraindicates compression1.3: suggests calcified arteries (e.g. diabetes) → false reading• Consider: venous Doppler, biopsy (non-healing), ulcer swabs (if infected), patch testing (dermatitis)📌 Management• Compression therapy – gold standard for healing and preventing recurrence• Debridement and wound dressings (e.g. foam, hydrocolloids)• Topical steroids – for venous eczema• Antibiotics – only if signs of infection• Pentoxifylline 400mg TDS – for refractory ulcers• Lifestyle: leg elevation, mobility, skin care• Long-term compression hosiery (Class 2 or 3) post-healing• Referral to vascular if ABPI <0.8, suspected malignancy, poor healing, or unusual site📌 Complications• Local infection, cellulitis• Pain, delayed healing• Psychological impact• Malignant transformation (Marjolin’s ulcer)• High recurrence if compression not maintained📌 Prognosis• ~45% heal within 6 months in community• ~70% heal with specialist care• Recurrence in 26–70%, especially if ulcer >1 year or large• Poor prognostic signs: chronicity, large size, arterial disease, poor compliance📎 More MSRA Resources for Venous Ulcer📝 Revision Notes: https://www.passthemsra.com/topic/venous-ulcer-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/venous-ulcer-flashcards/💬 Accordion Q&A Notes: https://www.passthemsra.com/topic/venous-ulcer-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/venous-ulcer-rapid-quiz/🎓 Full Course: https://www.passthemsra.com/courses/dermatology-for-the-msra/#MSRA #MSRARevision #MSRATextbook #MSRAQuiz #MSRAQuestionBank #MSRAFlashcards #MSRAQ&ANotes #MSRAAccordions #MultiSpecialtyRecruitmentAssessment #MSRAOnlineRevision #MSRARevisionWebsite #VenousUlcer #Dermatology
