When is it time for Vein Mapping?

When a patient is experiencing some classic symptoms of venous insufficiency—issues such as aching and heaviness in the legs, cramping, fatigue, and leg restlessness—it’s necessary to see what’s going on with the veins.

This is the job of vein mapping. Here’s more about how we do this important diagnostic test at Southwest Vein & Leg Center.

What is Vein Mapping?

Vein mapping is just as it sounds; it creates a map of the patient’s leg veins. This is used in the diagnosis of venous reflux and as a guide for treatments. In vein mapping, an ultrasound probe uses sound waves (doppler) to view or “map” the venous system and determine what vessels are not functioning as they should. As the ultrasound transducer is moved up and down the legs, the sound waves are recorded, and the information is converted into moving images. This mapping allows our providers to develop a customized treatment plan based on the results of the mapping. This mapping is also used to determine if the procedures will be covered by insurance.

How to Prepare for the Vein Mapping Procedure

These diagnostic tests only take about an hour from start to finish. You’ll need to wear loose-fitting clothing and you should leave your jewelry at home. You don’t need to restrict your diet in any way, but it’s a good idea to drink a couple of glasses of water prior to your appointment. Avoid caffeine before your session.

It’s Important before your mapping session that our staff has a good idea of what’s going on with your legs. Are they cramping? Do they feel heavy when moving them? Have you noticed discoloration? Have you had any lesions or skin ulcers that took a long time to heal?

What to Expect from the Vein Mapping Procedure

When you arrive for your vein mapping, you will be guided to an exam room to change into a loose pair of shorts that will be provided to you. You will stand on a raised platform for approximately 25-30 minutes while our registered vascular technologist uses the ultrasound machine to map the anatomy of your veins. The vein mapping process is identical to the vein screening but takes approximately 30 minutes as it is a more in-depth evaluation. The mapping helps determine what veins need to be treated and allows the physician to decide the best-individualized treatment plan for you.

Is Vein Mapping Painful?

These ultrasound tests are completely painless. Ultrasound energy has been used for decades throughout the medical world, and it has no adverse effects on the human body.
