Dermoscopic findings in chronic venous insufficiency

Area of Science:

• Dermatology
• Vascular Medicine
• Medical Imaging

Background:

• Chronic venous insufficiency (CVI) is a condition that leads to noticeable changes in the skin.
• Understanding these cutaneous manifestations is crucial for diagnosis and management.

Purpose of the Study:

• To investigate and document the specific dermoscopic findings associated with chronic venous insufficiency.
• To correlate clinical presentation with dermoscopic observations in CVI patients.

Main Methods:

• A prospective observational study included 80 adult patients diagnosed with CVI.
• Patients underwent clinical examination, duplex ultrasound, and detailed dermoscopy.
• Exclusion criteria included pregnancy, other causes of edema/pigmentation, active ulcers, prior venous interventions, arterial insufficiency, and DVT.

Main Results:

• Dermoscopy revealed accentuated pigment networks (105 limbs) and various vessel morphologies including dotted (67 limbs) and linear curved vessels (45 limbs).
• Skin changes observed included diffuse white scales (56 limbs), structureless areas (20-18 limbs), and blue-grey structures (34-6 limbs).
• Common clinical findings were pigmentation (120 limbs) and varicose veins (138 limbs).

Conclusions:

• Dermoscopy effectively identifies characteristic changes in skin vessel morphology, pigmentation, and scaling patterns in CVI.
• These findings highlight dermoscopy's utility in assessing CVI-related cutaneous alterations.
• Further research with longitudinal studies is recommended to understand the progression of CVI over time.
