ARTERIAL AND VENOUS DOPPLER

It is a non-invasive technique based on changes in the ultrasonic frequency emitted when reflected in different body tissues and permits the visualization of vascular (ultrasound image) and extravascular structures as well as the study of venous flow (Doppler effect).

Venous ultrasound

The Doppler for venous ultrasound is currently the most accurate and necessary tool for the study and diagnosis of venous pathology. It represents a real technological revolution in the study of the venous system, both in the field of exploration of venous thrombosis, and in the diagnosis of severe venous thrombosis (DVT).

Differential Diagnosis

The echo-Doppler is used for differential diagnosis of DVT with muscle rupture, ruptured popliteal cysts, popliteal venous aneurysms (thrombosed or not), popliteal artery aneurysm, tumors (sarcomas), etc.

Previous preparation is not required.

Material utilized:

• Eco Doppler scanner coupled to and / or color Doppler.

• 2.5-3 MHz echography (abdomen).

• 5 to 7.5 MHz echography (main vessels) to 10 to 13 Mhz.

• Pulsed Doppler 5 MHz approx

• Continuous Doppler.

The venous Doppler ultrasound is used to:

• View all sural femoral-popliteal and iliac venous trunks, and lower vena cava: Aplasia, dysplasia, splits, venous aneurysms.

• Diagnose venous thrombosis.

• Diagnose superficial venous insufficiency (size and location).

• Study Peripheral venous structures for differential diagnosis.

• Study compression.
