EVLA- Endovenous Laser Ablation

EVLA is performed under local anaesthetic, there is no need for a General Anaesthetic- in fact using General Anaesthetic to perform Endovenous Laser Ablation:

adds the risk of an unnecessary general anaesthetic
adds extra cost (for the anaesthetist and general anaesthetic theatre equipment and theatre)

To perform EVLA, the surgeon needs a map of the veins to show which ones are the problem. This map is made using Duplex Ultrasound.
At the EVLA procedure, the surgeon uses ultrasound to find the vein to be treated. The veins that can be treated are the main venous trunks of the legs:

Great Saphenous Vein (GSV)
Small Saphenous Vein (SSV)

Their major tributaries such as the Anterior Accessory Saphenous Veins.
Under ultrasound control, a needle is put into the vein near the knee or ankle. A wire is passed into the vein and a long ‘sheath’ is passed up the vein to the top. This ‘sheath’ is a thin tube about the width of a biro refill.
The ultrasound is used to position the end of the sheath exactly.
Local anaesthetic is injected around the vein – again using ultrasound to make absolutely sure the fluid is in the right place. The local anaesthetic fluid has 3 uses:
Local anaesthetic numbs the vein and the surrounding tissue
Adrenaline in the mixture causes the vein to contract onto the laser sheath giving good contact
The volume of fluid disperses the laser energy – making sure the tissues around the vein are not harmed when the vein is destroyed by heat.

Best Diode Laser for Veterinary Laser Surgery As growing numbers of veterinary clinicians are beginning to appreciate the many ways in which a laser can benefit their patients and their practice, Dimed has designed a family of fine surgical Diode laser systems that combine state-of-the art laser science with the latest advances in digital technology. The Dimed laser provides unparalleled precision and control (it is able to remove a single layer of cells, if desired), and yet offers enough power to perform large animal surgeries. An Dimed veterinary laser system can help expand the scope of the veterinary practice – the unique hemostatic properties of the laser beam and the ability to treat previously inaccessible sites allow the clinician to perform procedures that he or she may not have considered practical using conventional scalpel method.

Class IV Lasers in Physical Therapy

Class IV Lasers in Physical Therapy Laser is an acronym for:  L ight  A mplification from the  S timulated  E mission of  R adiation Laser Classifications  Lasers are classified into four broad areas depending on the potential for causing biological damage.  When you see a laser, it should be labeled with one of these four class designations:  Class I These lasers cannot emit laser radiation at known hazard levels.  Class I.a This is a special designation that applies only to lasers that are "not intended for viewing," such as a supermarket laser scanner. The upper power limit of Class I.A. is 4.0 mW. Class II These are low-power visible lasers that emit above Class I levels but at a radiant power not above 1 mW.  The concept is that the human aversion reaction to bright light will protect a person.  Class III.a These are intermediate-power lasers (cw: 1-5 mW), which are hazardous only for intrabeam viewing. Most pen-like po...

Photons are small packets of light energy—in the form of waves— with a defined wavelength and frequency. Photon energy is able to more effectively penetrate the skin and underlying structures, therefore accelerating the healing process. Light travels at a constant speed and oscillate up and down as it moves forward. However, all light is not the same. It is measured in wavelengths, with each wavelength of light representing a different color of the spectrum. The number of oscillations per second represents the frequency of each wavelength; shorter waves have a greater frequency than longer waves. Laser energy is coherent (well-ordered photons), monochromatic (single-color) light energy. When produced as a narrow, bright beam. Laser light holds its intensity unti...
