Vein mapping procedures are usually done in conjunction with some sort of bypass surgery. The procedure uses high frequency sound waves transmitted to the veins through a hand-held transducer. One or both legs will be scanned. In some cases your doctor will request that the location of your veins be marked on your leg(s). To do this, the technologist uses the hand-held, ultrasound transducer to view your veins. An assistant marks your leg to form a picture of the location of the vein(s) the surgeon may use for your bypass procedure. The technologist will videotape the study for later evaluation by the interpreting physician.
For this procedure you will be lying on your back. Gel will be applied to your skin, one area at a time, and the transducer will be moved around the area to view the veins from different angles.
