Check lower limb venous duplex scanning


Heaviness and pain in the legs, swelling, swollen veins - undeniable signs of existing problems with blood circulation. Such people need a special survey to assess the state of the venous blood flow. Find out what's happening, will help duplex scanning veins of the lower extremities - modern sparing methods of visualization of the affected areas.

What is duplex scanning

Regular inspection of the problematic limbs gives only a General picture of the severity of their condition. The doctor-phlebologist or vascular surgeon need to know what sections of the affected veins and to what extent to later decide on surgery. Such information will be very useful in the postoperative period when there is a risk of thrombosis or require the control of dynamics of treatment.

Diseases of the venous network is very insidious: they can be asymptomatic or with minimal and transitory symptoms, so timely identification of incipient problems widely used method of screening using ultrasound.

For this you need to "see" in Vienna. To make it possible, using duplex scanning - look ultrasound, which displays a two-dimensional dynamic image on a monitor apparatus. The image is in duplex scanning is supplied in color as opposed to the outdated simple ultrasound.

Evaluates specialist during the examination?

The two-dimensional image shows:

  • The condition of the vascular walls
  • The movement of blood
  • Work valve system

All this information and allows you to properly identify the affected areas, to accurately determine the diameter of the lumen of the vascular, their permeability, the presence of blood clots, thickening.

The diagnostic procedure takes less than 45 minutes.

Why duplex scanning is better?

Duplex scanning of lower limb veins has replaced Doppler, which makes it impossible to assess structural changes in the vessel walls: it only shows the direction of blood flow, its speed. Using the Doppler method cannot be installed and the diameter of the lumen of blood vascular.

The scanning procedure absolutely safe: ultrasound has no harmful effects on humans, so this method of diagnosis can be used as many times as needed. There is also no age contraindications and is not prohibited duplex monitoring duringpregnancy, and diseases that traditionally have a variety of restrictions on the methods of examination and treatment.

Scanning the state of the vascular of the legs painless - it does not involve incisions, punctures and other traumatic manipulation. Not used here and anesthesia, which eliminates the risk of allergic reactions to injected anesthetic drug.

Thus, it is also a non-invasive method of examination that gives patients the opportunity to lead their usual lifestyle.

Indications for use of duplex scanning of the veins

Any disease associated with impaired venous blood flow is an indication for the purpose of duplex scanning veins of the lower extremities. The most common pathology - phlebitis, varicose veins, atherosclerosis of brain vascular and visceral branches of the abdominal aorta, of the aneurysm.

As indications for the procedure can serve as patient complaints and objective data of medical examination, which recorded the following results:

  • Swelling of the lower extremities or complaints of passing the evening swelling
  • Pain at rest and during walking
  • Cramps in the muscles and toes
  • The color change of the extremities (pallor, redness, pigment spots), the appearance of spider veins
  • Lack of pulse in the legs
  • Trophic ulcers

The indications of direction on the duplex examination are those complaints that, at first glance, as the feet are not connected:

  • Dizziness when walking and at rest
  • The appearance of spots before eyes
  • Headaches, pain in the neck
  • Injuries to the neck
  • Migraine attacks
  • Insomnia or drowsiness
  • Pressure surges

The reason is that the vascular system of the human cycle, in which everything is interconnected: problems in one Department will inevitably entail the deterioration of other systems and organs.

Duplex scanning is an effective method of control in the postoperative period, when the vascular surgeon monitors the dynamics of treatment and change the condition of the patient (possible deterioration or improvement). According to their results, adjustments are made to the treatment plan, aimed at, for example, dissolving or removing blood clots.

How is the procedure of duplex scanning

The procedure is performed on an outpatient basis and does not require any special approach on the part of the patient came for examination veins of the lower extremities, the person only needs to provide the doctor access to the femoral crease.

Pants need to come off, and dress or skirt to just lift up, so womeneasier to come on the procedure in such clothes.

The patient lies on the couch, and the doctor starts the examination by applying a sensor device alternately to each leg in order to obtain data on the condition of the vessel. To facilitate sliding and enhance transmission of ultrasound sensors applied to the gel. The doctor moves the sensor and asking the individual to change position, hold your breath as you progress in certain fields.

Second position in which duplex scanning is performed, standing. This is the final stage of the procedure, which complements the already obtained data on the condition of the vascular of the legs.

Preparing to scan

In preparation for duplex scanning veins of the lower extremities does not require any special diet: the patient is assigned to such a study, continues habitually to eat, to keep his usual drinking regime.

The performance of surveys using the duplex method depends on the quality and standard of the equipment used, and the skills of the interpreter, so just choose a good clinic to receive reliable and objective information about the state of the vascular of the legs.
