Compression ultrasound is a crucial vascular imaging technique, primarily used to diagnose deep vein thrombosis (DVT). This non-invasive method involves applying direct pressure with an ultrasound transducer to assess vein compressibility. Healthy veins readily collapse under pressure, whereas thrombosed (clot-filled) veins remain distended, indicating the presence of a clot. This real-time assessment helps differentiate DVT…

A non-compressible vein, a critical finding in vascular ultrasound, indicates the presence of an intraluminal thrombus (blood clot) preventing the vein from collapsing under direct transducer pressure. This lack of compressibility is the primary diagnostic criterion for acute deep vein thrombosis (DVT), a potentially life-threatening condition. Identifying a non-compressible vein is crucial for prompt diagnosis…

A thrombus, in the vascular context, is a blood clot that forms within a blood vessel or heart chamber, obstructing blood flow. In medical ultrasound, thrombi appear as echogenic (bright) masses within the vessel lumen, often causing partial or complete occlusion. Identifying and characterizing thrombi is crucial for diagnosing conditions like deep vein thrombosis (DVT)…
