Chronic deep vein thrombosis (DVT) in vascular ultrasound refers to a blood clot that has been present for an extended period, often weeks to months. Unlike acute DVT, chronic clots may be more organized, adherent to the vessel wall, and less likely to embolize acutely, though they can still lead to post-thrombotic syndrome. Ultrasound findings in chronic DVT often include evidence of vessel wall thickening, scarring, residual luminal material, and the absence of acute compressibility.
Medical professionals utilize vascular ultrasound to assess the extent and characteristics of chronic DVT. This non-invasive imaging technique helps differentiate chronic from acute thrombus, guide management strategies, and monitor for complications. Early detection and characterization of chronic DVT are crucial for patient care and preventing long-term venous insufficiency.
