An Upper Limb Vein Map for Surgery Ultrasound is an ultrasound scan of the superficial veins in your arms from the shoulder to the wrist. The doctor usually wants to know if the main superficial veins are present in the arms and if they are of a size that can be used for bypass surgery. The diameters of the veins are measured and documented. Occasionally, if surgery is within days, the veins are marked on the arms with a permanent marking pen.
- You will be taken to a private room. A staff member will explain the procedure and answer any questions you may have.
- You will be asked to remove clothing to access the area to be examined and to sit on the edge of the examination couch or sit up against the back of the couch.
- Gel is placed on the area of interest so that the sound waves can pass through to the relevant veins. The ultrasound probe is moved over the veins. Diameters of the veins are measured.
- If the Doctor requests, the vein location is marked on the skin with a permanent marking pen.
- The examination takes 30 minutes.
