Venous reflux, central to vascular health, occurs when valves in veins weaken or fail, causing blood to flow backward, typically in the legs. This dysfunctional flow, rather than moving towards the heart, pools in the lower extremities, increasing pressure and leading to conditions like chronic venous insufficiency, varicose veins, and swelling. Understanding venous reflux is critical for diagnosing and managing these common vascular disorders.
In medical ultrasound, Doppler studies are essential for accurately detecting and quantifying venous reflux. Sonographers use specialized techniques to visualize blood flow patterns in real-time, identifying the direction and duration of reflux. This non-invasive assessment guides treatment strategies, from conservative management to minimally invasive procedures, ensuring targeted interventions for optimal patient outcomes in vascular medicine.
