Duplex scanning( duplex dopplerography) of the veins of the lower extremities is one of the most progressive techniques that allows obtaining objective data on the state of the circulatory system in the veins of the lower limbs.
In total, there are two types of examination of the vessels of the lower limbs:
- UZDG( ultrasound dopplerography);
- DS( duplex scanning).
Apparatus for ultrasound diagnosis today can perform both these types of studies.
Duplex scanning allows you to view the vessel itself, its lumen, location, wall and blood flow pattern.
Ultrasound duplex scanning( UZDS) is the crown of modern methods of diagnosis of venous diseases.
Without it, it is impossible to establish the correct diagnosis and prescribe the optimal treatment.
For all patients with venous diseases( thrombophlebitis, thrombosis, varicose veins and others) is mandatory.
This type of research has the following advantages:
- does not require special preparation;
- no side effects( not hazardous to health);
- is painless;
- is safe;
- is not invasive( does not break the skin);
- there are no age restrictions.
UZD allows you to examine the vessels on the monitor screen online and find in them, not visible to the eye, the pathology:
- presence of thrombi, their nature, size, change in state;
- presence and stage of thrombosis;
- the source( cause) of relapse after phlebectomy or sclerotherapy;
- functional mode of perforating veins;
- patency and condition of deep and superficial veins;
- condition of the venous valve apparatus;
- condition of the venous walls and circulatory system in them.
The time required for this type of study is about 45 minutes.
The most reliable and modern method is CDS( color duplex scanning).
In this type of study, ultrasound instruments of third generation vessels are used, greatly expanding the usual capabilities of ultrasound devices.
Advantages of CDS:
- , a phlebologist can accurately and quickly select a specific individual treatment technique;
- helps to avoid formidable varicose thrombotic complications;
- provides a detailed picture of pathology;
- allows you to conduct very high-quality examinations;
- image on the monitor screen can be obtained, both in black and white, and in color tones.
The total duration of the procedure is about 45 minutes.
Procedure for duplex scanning of lower limb veins
The patient is placed on his back, lifting the upper part of the body slightly.
The study begins with the inguinal zone, which is processed by a sensor of 4-7 megahertz.
After this, the femoral vein from the podmyshchelka femur is traced distally and with variable compression.
Also, the course of the femoral deep vein is noted.
Descending the leg, the tibial fore veins are scanned.
After this, the patient is turned over on the stomach.
A small roller is placed under the knee. The popliteal vein is inserted into the cross section.
First, the vein is proximally traced, and then variable compression is performed.
Further, the vessels are traced distally, with a separate evaluation of the tibial and peroneal veins.
Special attention is paid to the proximal sections of the peroneal veins.
The conclusion of a specialist is issued as a result of clinical symptoms and findings.
Take care of yourself.
Stay healthy!
