This venous clinical severity score (VCSS) calculator is used to monitor changes in venous disease severity based on lower extremity symptoms. Below the form there is in depth information on the origin of the model, instructions on how to perform the assessment and details on the revised version.
How does this venous clinical severity score (VCSS) calculator work?
This health tool belongs to the Venous Severity Scoring (VSS) system, along the venous disability score (VDS) and the venous segmental disease score (VSDS).
The VCSS is derived by the American Venous Forum from the CEAP classification (clinical grade, etiology, anatomy, pathophysiology) and provides means by which clinical outcomes in venous disease can be monitored in time.
Compared to the CEAP, VCSS is said to be more responsive to changes in disease severity, thus making it great for progressive rankings. It proved good inter and intra observer reproducibility and is often cited in quality of life assessments.
Scores that can be obtained range between 0 and 30. The results for each leg can be used to monitor progress, especially before and after venous intervention or to monitor compliance to compressive therapy.
The items scored in the VCSS are:
■ Pain – for example, aching, heaviness, fatigue or soreness, all presumed with venous origin. The clinician is advised to describe the types of pain to the patient.
■ Varicose veins – must be more than 4 mm to qualify for differentiation. The clinician examines each limb in standing position and assesses superficial veins.
■ Venous edema – presumes venous origin. The clinician examines the pattern of leg edema.
■ Skin pigmentation – does not include focal pigmentation over varicose veins or pigmentation caused by other diseases.
■ Inflammation – that is more than recent pigmentation (for example signs of erythema, dermatitis, venous eczema).
■ Induration – presumes venous origin of secondary skin and subcutaneous changes such as fibrosis, hypodermitis, white atrophy and lipodermatosclerosis.
■ Number of active ulcers – based on the examination of each leg.
■ Active ulcer duration – accounts for the longest active.
■ Active ulcer size – accounts for the largest active.
■ Compressive therapy – the clinician needs to choose the level of compliance with the therapy.
Revised venous clinical severity score
The following table introduces the revised VCSS:
|Item||Absent (0 points)||Mild (1 point)||Moderate (2 points)||Severe (3 points)|
|Varicose veins||None||Few||Calf or thigh||Calf and thigh|
|Venous edema||None||Foot and ankle||Above ankle, below knee||To knee of above|
|Skin pigmentation||None||Perimalleolar||Diffuse, lower 1/3 calf||Wider, above lower 1/3 calf|
|Inflammation||None||Perimalleolar||Diffuse, lower 1/3 calf||Wider, above lower 1/3 calf|
|Induration||None||Perimalleolar||Diffuse, lower 1/3 calf||Wider, above lower 1/3 calf|
|No. active ulcers||None||1||2||≥3|
|Active ulcer size||None||<2 cm||2 – 6 cm||>6 cm|
|Ulcer duration||None||<3 months||3 – 12 months||>1 year|
|Compression therapy||None||Intermittent||Most days||Fully comply|
The revised version focused on clarifying some of the ambiguities and on simplifying the application of the score.
Some recommend that the revised VCSS to be used for clinical outcome assessment in the case of patients who underwent therapy for varicose veins.
