visuel preventex

Preventex is a range of anti-embolism stockings specifically designed to reduce the risk of developing a blood clot or deep venous thrombosis caused by the slowing of the blood due to surgery or a prolonged period in bed.

Composition and Properties

Preventex is composed of Polyamide and elastane and is available in a range of sizes, knee-length, thigh-length and thigh length with belt to accommodate the different patient morphologies.

It has recently been improved and has a range of features and properties to ensure correct fitting and patient comfort.

  • A breathable silicon band on the thigh-length stockings for comfort and to maintain correct positioning
  • A 2-way stretch gusset to prevent a tourniquet effect and enhance patient comfort
  • An inspection opening under toes to provide easy access for the clinician
  • Anatomically designed heel to maintain the correct compression at the ankle and enhance patient comfort
  • Permanent size indicator sewn into the feet of both stockings for ease of identification

Preventex is now softer than before with a wider ankle to allow for easy application and fitting

Anti-embolism stockings work by providing graduated compression to the leg which increases the linear velocity of venous blood flow, reduces venous wall distension and improves valvular function.

Conforms to the Sigel Profile for anti-embolism stockings, producing graduated compression of 18mmHg at the Ankle, 14mmHg at the Calf and 8mmHg at the Thigh; as recommended by NICE (2010)2


PREVENTEX® anti-embolism stockings are indicated for people undergoing surgery or who have recently undergone surgery and any person who may be at risk of developing Deep Venous Thrombosis which can lead to Pulmonary Embolism.


Dermatitis, vein ligation (immediately post-operatively), gangrene,recent skin grafts, severe arteriosclerosis, massive oedema and extreme leg deformity.

Fitting instructions

1) Insert hand into stocking as far as the heel area. Grasp heel section and turn stocking inside out as far as the heel.

2) Insert the foot into the stocking, ensuring the patient’s heel is in the blue heel area.

3) Gently ease the stocking up the leg working in small sections, to ensure even pressure application across the whole leg.

4) Check that the toe inspection opening is correctly positioned below ball of foot and stoking feels comfortable.

Recommendations & Guidance for anti-embolism stockings (AES)

  • Always measure legs as per manufacturer’s guidelines, to ensure accurate and comfortable fit prior to stocking application.
  • Legs should be re-measured if oedema or post-operative swelling develops, and
    stockings re-fitted.
  • Stop the use of anti-embolism stockings if there is marking, blistering or discolouration of the skin, particularly over the heels and bony prominences, or if the person experiences pain or discomfort.
  • Anti-embolism stockings should be worn before, during and after surgery or hospital stay until a person’s mobility is no longer significantly reduced.
  • Anti-embolism stockings need to be worn as much as possible, both night and day; however, they may be removed for up to 30 minutes to allow for bathing or showering.
  • Remove anti-embolism stockings daily for hygiene purposes and to inspect skin condition. In people with a significant reduction in mobility, poor skin integrity or any sensory loss, inspect the skin 2 or 3 times a day, particularly over the heels, toes and bony prominences.

Patient advice

  • While you are in hospital receiving treatment, there is a risk of developing a blood clot, known as a Deep Venous Thrombosis (DVT) in the lower leg, caused by a slowing of the blood flow through the veins due to increased time spent in bed or because of an operation.
  • To reduce this risk, you have been prescribed PREVENTEX® anti-embolism stockings which provide the correct pressure on the leg to help increase the blood flow back to the heart and to prevent the formation of blood clots in the leg.
  • To ensure the correct size of PREVENTEX® stocking is fitted, the nurse will measure your ankle, calf and thigh circumference and also your leg length, depending on whether you are having knee length, thigh length or waist high stockings.
  • The two-way stretch of PREVENTEX® enables easier application and comfortable fit along with the anatomically designed blue heel which helps ensure an accurate fit and positioning. The larger toe area allows more space for toe movement and comfort and the inspection opening (which remains under the ball of the foot) allows for easy inspection of the toes.
  • Permanent sizing is visible on both feet of the stockings for ease of size identification. PREVENTEX® stockings are latex free.
  • Never roll your stockings down while you are wearing them as this will alter their performance and could constrict blood flow by causing a tourniquet effect.
  • Your PREVENTEX® stockings need to be worn as much as possible, both night and day; however, they may be removed for up to 30 minutes to allow for skin inspection, bathing or showering.

Measuring guide

  • Preventex AES are available in S, M, L, XL, XXL+ and XXXL+.
  • Measure the patient at the widest point of the calf (C) and, if fitting thigh length stockings, the widest point of the thigh (T).
  • For thigh circumference over 81 cm, choose below knee only.
  • For improved fit, Preventex come in three lengths – Short++, Regular and Long.
  • For the below knee, measure the distance from behind the knee to the bottom of the heel (L1).
  • For thigh length, measure the distance from the buttock fold to the bottom of the heel (L2).

+XXL and XXXL are available in below knee only
++Short is available in thigh length only
