Diagnosis of varicose veins

Ультразвуковое дуплексное сканирование вен (УЗДС, УЗДГ вен)

How is ultrasound examination of the veins of the lower extremities at the reception of the phlebologist?


The leading role in the diagnosis of varicose veins of the lower extremities today is ultrasound (ultrasound examination of the veins of the lower extremities). And there are many reasons for this: firstly, for this procedure, no special preparation of the patient is required, Secondly it is absolutely painless, therefore does not require anesthesia, third - the speed of the result, and finally fourthly - efficiency and accuracy of this result!

But in patients before visiting the phlebologist, a number of questions arise related to the terminology of this procedure. What is UZDG (ultrasound dopplerography)? What is ultrasound duplex scanning? What is a CDC (color Doppler mapping) or triplex scanning? What is the difference?


Let's answer these questions and decide which way to better assess the condition of the venous vessels of the lower extremities.

UZDG (ultrasound dopplerography) - one of the most accessible methods of research, based on the effect of Doppler (named after the Austrian physicist-mathematician Doppler), which consists in recording the measurement of the velocity of reflected sound waves from moving blood cells. Allows you to study only one function - the permeability of the vessel based on the flow of blood. Performed blindly, the sensor is placed on the points of the approximate projection of the vessel. If there is a violation of the patency of the vessel, it is impossible to clarify the cause of this violation, because there is no visualization of blood vessels.

UZDS (ultrasonic duplex scanning) — данное исследование сочетает в себе два (дуплекс) режима обследования. Обычный (традиционный) режим ультразвукового сканирования, который позволяет видеть вену в двухмерном черно-белом изображении, и доплеровский режим, который позволяет определить «текучесть» крови на основании графика. В результате врач получает полную визуализацию сосуда на экране, позволяющую определить состояние сосудистой стенки, наличие тромботических масс в просвете, работу клапанного аппарата, извитость сосуда и аномалии, а также характер кровотока: его скорость, турбулентность.


CDC (color Doppler mapping) or triplex Is not some other method of investigation. This is the same UZDD device (ultrasonic duplex scanning), which operates in an additional third mode (three-triplex), which consists in visualizing the vessels in a color image. Through this, a more informative examination is achieved, which allows to determine vascular patency, speed and direction of blood flow, level of thrombotic lesion with high accuracy.

It is worth noting that ultrasonic waves are considered absolutely safe and have no negative effect on the adult body. Ultrasound can be repeated many times if necessary during treatment.

Based on the foregoing, we can conclude that to date, ultrasound (ultrasound duplex scanning) vessels in color mode is considered one of the best and most demanded methods in diagnosing varicose veins of the lower extremities.


В нашем центре «МИФЦ» все флебологи имеют сертификат для выполнения ультразвукового сканирования, то есть все специалисты прошли многоуровневую профессиональную переподготовку и могут выполнять данное исследование. Кроме того, много лет, работая на самых современных ультразвуковых сканерах доктора нашего центра стали экспертами в области диагностики заболеваний вен нижних конечностей.

All this allows us to perform the most complicated surgical interventions on the veins of the lower extremities under ultrasound control, including endovascular operations (without incisions) and complex reconstructive surgeries in the relapse of varicose veins.
