Venous Study

Venous study involves the study of the human vein for anomalies to identify potential disease or injury. Veins are the blood vessels within the human body that carry blood to the heart, moving against the force of gravity. A variety of tests diagnostic tests can be performed to assess for vein damage and disease.

  • Venous Duplex Study - an imaging test using ultrasound technology to view your body's veins to determine whether there is a presence of blockage or thrombus (clot). Blood flow is stimulated with slight compressions to designated locations on the body in order to gauge blood flow.
  • Pulse Volume Recording (PVR), with Segmental Blood Pressure Impedence - This test measures venous capacity and blood flow. The technician records the change in air volume from a PVR cuffs that are positioned around the leg by monitoring blood as it pulses through the blood vessels.
  • Photoplethysmography (PPG) - This test uses infrared light to assess blood flow near the skin's surface. A picture is then created with light waves to show what is taking place in the veins.
  • Vein Mapping - The process of measuring, locating, and marking veins in the lower or upper extremities to be used for bypass surgery or hemodialysis access.
