Non Invasive Testing
The Iowa Clinic Vein Therapy Center has a non-invasive vascular laboratory that is accredited by the Intersocietal Commission for the Accreditation of Vascular Laboratories.
Why would I need non-invasive testing?
To identify where and how badly your veins are damaged, your physician may order tests to evaluate blood flow. These non-invasive tests are painless and do not use needles, dyes, or x-rays.
During a doppler evaluation, your doctor, nurse, or trained technician uses a special stethoscope to listen for changes in blood flow that may indicate a clot or valve problem.
This technique bounces sound waves off of your vein to create an image that shows the size and shape of your vein, as well as the amount of blood flowing through it.
Endovenous Laser Therapy - EVLT
This revolutionary treatment can eliminate your varicose veins non-surgically right in the office. After just 10 minutes of recovery you will be able to walk right out, free from your varicose veins and free to return to your normal activities the very next day.
The EVLT™ Procedure deals with the incompetence of the greater saphenous veins. Unlike surgical stripping, EVLT permanently closes off the vein while leaving it in place. It uses the energy from an 810 nm diode laser delivered by a fine fiber-optic probe. As it is only the probe and a slim sheath which need to enter the vein the whole procedure is performed via a tiny skin nick, so there will be no post operative scarring. The probe is guided into place using ultrasound and the procedure is performed under strictly local anesthetic of a similar type used by dentist to numb the treatment area.
Sclerotherapy is the most commonly used treatment for small diameter (<5mm) veins, such as spider veins. In Sclerotherapy, a liquid is injected with a tiny needle into the vein that causes inflammation of the vein walls and causes the vein walls to stick to one another, collapsing the walls together. This solution and the use of a compression stocking, effectively prevents the vein from working and it stops carrying blood. The vein therefore disappears with time.
Small veins are effectively removed by Sclerotherapy but veins will often reappear if the underlying causes, incompetent blood vessels, are not treated. Sclerotherapy is associated with brown discoloration of the vein that may take up to one year to disappear and usually requires repeated treatments. It rarely can cause skin ulcers and as with all medications, some patients may have an allergy to the solution.
Ultrasound Guided Sclerotherapy
Ultrasound guided sclerotherapy is used for the treatment of deeper veins that cannot be seen or felt and for larger superficial veins.
Using ultrasound, a solution is injected into the veins causing the vein walls to collapse. Compression stockings are then used to make sure that the vein walls stay collapsed. Ultrasound guided sclerotherapy requires expert knowledge that conventional sclerotherapy does not. Once again, as the larger veins are treated, smaller spider and reticular veins will often disappear.
The advantages are no scarring and smaller veins disappear, while the downside is brownish discolorations, allergic reactions and the rare development of skin ulcers.
