IVUS has the capacity to visualize nonocclusive thrombi that may be missed on traditional venography  and aid in distinguishing chronic vs. acute thrombosis. It can define luminal features, such as trabeculations and valvular issues, that cannot be captured on venography. Furthermore, The use of IVUS can identify with increased accuracy in luminal stenosis can also aid in determining stent sizing, the degree and length of venous stenosis which can reduce the risk of thrombosis and poor long-term patency.

Intravascular ultrasound (IVUS) is a catheter-based Ultrasound guidance system that is used during endovascular procedures. It provides a diagnostic ability to assess and to measure the severity of disease before treatment and also demonstrates the completeness of treatment after Stenting or Angioplasty. IVUS is now used in a wide variety of peripheral vascular interventions with Lower frequency catheters, such as the 10-MHz catheter. IVUS acts as a guidance system during balloon angioplasty and stenting. It can accurately calculate the degree of stenosis and this allows appropriate sizing of the balloon as well as of the stent to be implanted. In Venous Imaging, the degree of venous stenosis can be calculated precisely by measuring the cross-sectional areas and proved superior in showing trabeculations and webs that may be hidden in contrast medium.
