Venous Duplex Ultrasound (2 systems) is an ultrasound diagnostic method used to evaluate blood vessels and blood flow.

The examination is performed using ultrasound equipment that utilizes two assessment systems - B-mode and Doppler mode. These systems provide a comprehensive view of the vascular structure and any possible abnormalities.

The simultaneous use of both systems provides the physician with a comprehensive understanding of the body's hemodynamic status and enables an integrated assessment of parameters such as:

• Internal diameter of the blood vessels;
• Condition of the vessel walls;
• Direction of blood flow;
• Velocity of blood flow;
• Presence or absence of pathological changes (such as stenosis, thrombosis, or other abnormalities).

This two-system venous duplex ultrasound assessment is especially important in systemic or multifactorial conditions where a comprehensive evaluation of the vascular system is required.

In addition to gathering initial diagnostic data, it is also widely used in follow-up monitoring, as it allows for early detection of pathological changes, timely identification of risks, and the planning of subsequent medical decisions.

Venous Duplex Ultrasound (2 systems) represents a vital and effective component of modern vascular diagnostics.
