Upper and Lower Extremity Vein Mapping
  • The purpose of the exam is to evaluate the size of the superficial veins, to be considered for a possible arterial by-pass, or for the creation of a dialysis access graft, or fistula.
  • The exam typically takes 20 to 30 minutes and no test preparation is needed.
  • Patients should wear loose fitting cloths, that allows access to the arms or legs.
  • A water-based ultrasonic gel is applied to the skin and the Technologist will use an Ultrasound Transducer to acquire images.
