The aims and objectives of our study were to use shear wave elastography (SWE) for differentiation between acute and chronic deep venous thrombosis by characterizing of clot stiffness.

Ultrasound and shear wave images were obtained from 91 adults (aged 43.8±5.1) who underwent medical check-up in our hospital. Thefirst group (43 patients) with clinical and ultrasound findings of acute deep venous thrombosis of lower extremities. The second group, (48 patients) with chronic deep venous thrombosis. The diagnosis was based on clinical and ultrasound findings, which were obtained during venous duplex ultrasonography, color flow Doppler imaging with 2D-SWE according to American College of Radiology (ACR) guidelines and technical standards.The examinations were performed according to the...

Ultrasound foundlings of acute venous thrombosis were considered to be hypoechoic, homogeneous, structure on B-mode, vein dilatation, incompressibility of the vein during the ultrasound and were correlated with elasticity values 12± 1.7 kPa (p≤0.01).Ultrasound foundlings of chronic venous thrombosis, such as heterogeneous structure with hyperechoic component, incompressibility of the vein during the ultrasound exam were highly correlated with higher elasticity values 25± 1.08 kPa (p≤0.01).

Shear wave elastography can be used like an additional noninvasive method by characterizing clot stiffness for differentiation between acute and chronic deep venous thrombosis. The age differentiation of the deep venous trombosis could also be useful in diagnosing re-thrombosis of a previously thrombosed vein and create more effective and clinically relevant treatment protocols based on this findings.
