A deep venous thrombosis DVT ultrasound is used to image or see the clot. This examination purpose is to evaluate clot in the femoral and popliteal regions.
Using the SIFULTRAS-5.31 while imaging the deep veins of the leg, the physician tries to collapse or compress the veins. If a vein cannot be compressed because a clot prevents the vein from collapsing, a DVT diagnosis is made.
The other option is using the SIFULTRAS-5.34 color doppler ultrasound to detect abnormalities of blood flow. Sound waves are bounced off the blood within a vein.
Flowing blood changes the sound waves by the “Doppler effect.” The SIFULTRAS-5.34 can detect these changes and determine whether blood within a vein is flowing normally. Absence of blood flow confirms the diagnosis of DVT : Deep Venous Thrombosis
The ability to detect DVT using either of the wireless ultrasound scanner in the large veins above the knee is so good that when the test is positive, no further testing is necessary and treatment may be started.
So in brief, the SIFULTRAS-5.31 and SIFULTRAS-5.34 can be used to quickly rule in the diagnosis DVT : Deep Venous Thrombosis.
Proper patient and probe positioning, as well as the application of appropriate probe pressure at different stages of the examination are essential to accurately visualize and assess the femoral, saphenous, and popliteal veins for the presence of a thrombus.
