Common Misdiagnoses of Varicose Veins

Varicose veins are a common venous disorder characterised by enlarged, twisted veins, primarily in the legs. Despite their prevalence, varicose veins and their underlying cause—chronic venous insufficiency (CVI)—are frequently misdiagnosed, leading to ineffective treatments and worsening patient outcomes.

Understanding the common misdiagnoses associated with varicose veins is crucial for timely and appropriate care.

Common Misdiagnoses in Varicose Veins

1. Misdiagnosing Chronic Venous Insufficiency as Other Conditions

Chronic venous insufficiency (CVI) is the root cause of varicose veins, where vein valves fail to efficiently return blood to the heart, causing blood pooling in the legs. However, CVI symptoms such as leg swelling, aching, and heaviness are often mistaken for other health issues:

  • Kidney disease or heart failure – Leg swelling is frequently attributed to these conditions, leading to prescriptions of diuretics (water pills) that only provide temporary relief without addressing venous problems. Long-term diuretic use without proper diagnosis can cause dehydration, electrolyte imbalances, and kidney damage.
  • Lymphedema – Swelling from CVI can be confused with lymphedema (a lymphatic system disorder) and can delay the proper treatment.
  • Cellulitis – Leg inflammation caused by CVI is often misdiagnosed as cellulitis, a bacterial skin infection. This results in unnecessary antibiotic use, increasing the risk of antibiotic resistance and other complications. Patients may endure repeated antibiotic courses without symptom improvement.

2. Venous Dermatitis Mistaken for Other Skin Conditions

Venous dermatitis is a skin condition caused by chronic venous insufficiency, characterised by inflamed, itchy, and discoloured skin on the lower legs. It is often treated with steroid creams, which reduce inflammation temporarily but do not address the underlying venous disease. Prolonged steroid use can thin the skin and increase infection risk. Without treating the venous insufficiency, the dermatitis may worsen or progress to venous ulcers—painful, slow-healing wounds.

3. Venous Ulcers Treated Without Addressing Venous Insufficiency

Venous ulcers represent the most severe manifestation of untreated CVI. These wounds are often managed solely with topical treatments and wound care without investigating the venous cause. This oversight leads to recurrent ulcers and chronic wounds, which increase risks of infection, malignant transformation, and even amputation in vulnerable patients. Targeted vein treatments can heal ulcers effectively by correcting the underlying venous insufficiency.

4. Varicose Veins Confused with Other Causes of Leg Swelling and Masses

Varicose veins must be differentiated from other causes of leg swelling and lumps such as femoral or inguinal hernias, femoral artery aneurysms, lymphadenopathy, and lipomas. Proper physical examination and imaging are essential to avoid confusion with these conditions.

Why Misdiagnosis Happens

  • Symptom Overlap – Many symptoms of varicose veins and CVI—such as leg swelling, pain, and skin changes—overlap with other common conditions, leading to diagnostic confusion.
  • Lack of Awareness – Primary care providers may lack specialised training in venous diseases, resulting in the underrecognition of CVI and varicose veins.
  • Inadequate Evaluation – Failure to perform detailed history-taking, physical examination, and appropriate diagnostic imaging can result in missed or incorrect diagnosis.

Consequences of Misdiagnosis

  • Delayed Appropriate Treatment – Patients endure prolonged symptoms and disease progression without relief.
  • Ineffective or Harmful Treatments – The use of diuretics, steroids, antibiotics, or unnecessary surgeries can cause side effects and complications without addressing the vein disorder.
  • Progression to Severe Complications – Untreated CVI can lead to venous ulcers and infections.
  • Reduced Quality of Life – Chronic pain, swelling, skin changes, and wounds significantly impair daily functioning and well-being.

Improving Diagnosis and Management

  • Early Specialist Referral – Patients with leg swelling, varicose veins, skin changes, or chronic wounds should be evaluated by vein specialists who can perform detailed assessments and imaging.
  • Use of Diagnostic Tools – Ultrasound is the gold standard for assessing venous function and identifying issues.
  • Patient Education – Awareness of varicose vein symptoms and risks can prompt earlier medical consultation.
  • Multidisciplinary Approach – Collaboration among primary care, dermatology, wound care, and vascular specialists improves diagnostic accuracy and treatment outcomes.

If you experience symptoms like leg swelling, aching, skin discolouration, or chronic wounds, a consultation with our vein specialist at Delphi Clinic can help ensure correct diagnosis and effective varicose veins treatment.
