Diagnosis: Venous Leg Ulcer with Chronic Venous Insufficiency (Lipodermatosclerosis/Stasis Dermatitis)

What the image shows

Primary Diagnosis

Key Clinical Features Supporting This Diagnosis

• Ulcer located in the gaiter region (calf muscle to ankle), specifically the medial side - the area of the Cockett perforators
• Sloping edges with granulation tissue and slough on the floor
• Surrounding haemosiderosis (dark pigmentation from iron deposition)
• Lipodermatosclerosis - manifest as thickening, pigmentation, inflammation and induration of the calf skin
• Chronic, recurring nature

Differential Diagnoses to Exclude

1. Mixed ulcer (venous + arterial) - present in 15-30% of "venous" ulcers; check ankle-brachial pressure index (ABPI)
2. Arterial ischaemic ulcer - typically more painful, punched-out edges, on pressure points/foot
3. Neuropathic ulcer - check sensation; consider if diabetic
4. Vasculitic ulcer
5. Marjolin's ulcer (squamous cell carcinoma arising in a chronic ulcer) - biopsy if edges are raised/rolled or healing is absent
6. Infective ulcer - especially relevant in low/middle-income countries

Recommended Investigations

• ABPI (Ankle-Brachial Pressure Index) - mandatory to exclude arterial component before applying compression
• Duplex ultrasound - assess deep and superficial venous reflux
• Wound swab if signs of infection
• Biopsy if malignancy is suspected (raised, everted edges; failure to heal)
• Blood glucose, FBC, inflammatory markers

Management Principles

1. Compression therapy is the cornerstone - multi-layer compression bandaging (targets the underlying venous hypertension). Recent systematic review (PMID 38522455, 2024) highlights poor compliance as a major barrier.
2. Wound care - appropriate dressings (non-adherent, moisture-managing)
3. Elevation of the limb
4. Treat underlying venous incompetence - endovenous ablation or surgery where appropriate
5. Treat infection if present
6. Emerging adjuncts: platelet-rich plasma (PMID 41643347, 2026 meta-analysis shows clinical benefit) and photobiomodulation (PMID 41889013, 2026 meta-analysis shows improved healing)

Important clinical note: This patient appears to be in a resource-limited setting (outdoor environment, work clothing). Infections are a leading cause of leg ulcers in low/middle-income countries and should be actively considered and treated. Compression therapy compliance and follow-up will be key management challenges.

ECG Diagnosis: Left Bundle Branch Block (LBBB)

Machine-Reported Parameters

ECG Findings - Lead by Lead

1. QRS duration ≥ 120 ms (135 ms here) ✓
2. Broad, notched R in lateral leads (I, aVL, V5-V6) ✓
3. Absent septal q waves in lateral leads ✓
4. rS or QS in V1 ✓
5. Secondary ST-T wave changes (discordant - T waves opposite to QRS) ✓

Clinical Significance

• Ischaemic heart disease - most common; if chest pain is present, treat as STEMI equivalent (Sgarbossa criteria apply)
• Dilated cardiomyopathy (ischaemic or idiopathic)
• Hypertensive heart disease / LVH
• Valvular disease (especially aortic stenosis)
• Fibrosis of the conduction system (Lenegre's/Lev's disease)
• Severe trauma

Recommended Workup

1. Clinical history - chest pain, dyspnoea, syncope, hypertension, diabetes
2. Troponin - rule out acute MI (especially if new or unknown baseline)
3. Echocardiogram - assess LV function, wall motion, dimensions, valves
4. Prior ECG comparison - new vs. old LBBB changes management urgency dramatically
5. Stress echo or nuclear perfusion - for ischaemia assessment (resting/exercise ECG unreliable with LBBB)
6. If CHF signs present - consider CRT (cardiac resynchronisation therapy) - LBBB + cardiomyopathy with EF ≤35% is a class I indication

"LBBB has a weak predictive power in a young, asymptomatic population, but is quite ominous in an older population as a marker for increased risk of death, stroke, and CHF." - Pfenninger and Fowler's Procedures for Primary Care, 3rd Ed.
