When a leg bypass procedure is determined to be the best course of action in treating a blocked vein or artery, the next step is to identify a healthy vessel that may be grafted into the place of the diseased one. An ultrasound examination is commonly used for this purpose, through a procedure known as vein mapping. Vein mapping assesses the health of various veins that might be appropriate for the grafting process.
Vein mapping as a completely non-invasive procedure that involves no needles, dyes or discomfort. Ultrasound is used to emit sound waves into the body, which create an image of the veins on a screen. Ultrasound technology can also be used to assess blood movement inside the veins to determine whether the veins are healthy enough for the grafting procedure.
The procedure is performed while the patient lies down on the examination table. Warm gel is placed on the skin in the area to be examined. A handheld device known as a transducer is run across the surface of the skin, which sends sound waves to the vessels below. Patients may feel mild pressure from the transducer, but there is no pain throughout the examination.
Through vein mapping, we can identify the best possible veins to be used for a successful grafting procedure. To learn more about this non-invasive diagnostic tool, contact us at Northwest Vascular & Vein today.
