Chronic venous insufficiency occurs when your legs do not allow a steady flow of blood back to your heart. Venous duplex imaging provides information about valve function and the levels of involvement. The duration of reflux is known as “reflux time”. A reflux time of >0.5 seconds for superficial (greater saphenous and small saphenous) and >1.0 seconds for deep veins is used to diagnose the presence of reflux. Typically, the longer the duration of reflux time implies more significant disease. These exams are usually performed in a standing position.

Risk factors for venous insufficiency include:

  • Being overweight
  • Pregnancy
  • Family history of venous disease
  • Previous history of deep vein thrombosis
