Endovenous Laser Ablation of Varicose Veins with 1470 diode laser

Endovenous Laser Ablation of Varicose Veins


Varicose Veins
l   Common (40+ % of population)
l   Many venous symptoms
l   Underdiagnosed
l   Poor cosmesis
l   Long term - ulcers, haemorrhage, eczema
l   Public Rx funding poor

  Venous symptoms
 Aching
 Swelling
 Restless Legs Syndrome
 Cramps
 Burning sensation
 Itching, eczema
 Heaviness
 Tired legs
 Haemorrhage
 Ulceration
Worse with:
• standing
•menses
•hot weather

Clinical Signs of VVs
 Visible veins ( not necessarily)
 Oedema
 Eczema
 Haemosiderin brown staining
 Ulcers, or scars from healed ulcers
 CVI – telangiectasiae, cyanotic feet
 Lipodermatosclerosis
 Atrophie blanche
 Vulval aching / varices in pregnancy
 Pelvic congestion syndrome

High pressure/volume/flow deep system                                      Low pressure/volume/flow superficial system

Venous flow downwards,
distending vein walls,
venous hypertension,
Classification
 Class 1: telangiectases and reticular veins
 Class 2: varicose veins
 Class 3: oedema
 Class 4: skin changes without ulceration,
eg. eczema, pigmentation
 Class 5: healed ulcers
 Class 6: active ulcers
GSV: Great (long) Saphenous Vein
SSV: Small (short) Saphenous Vein

Endovenous Laser Ablation (EVLA)


Seldinger Technique with US guidance
 Minimally invasive
 J guide-wire to below junction (SFJ, SPJ)
 Catheter over guide-wire
 Tumescent local anaesthesia
 Laser fibre tip placed 2 cm distal to junction
 Position : US, transillumination, saline flush.
 Relaxed warm patient ideal
Mark vein to be treated                                   Iodine skin prep Vein Access


J wire inserted into access needle     Catheter sheath with stiffener
      

J wire removed & laser fibre inserted






Endovenous Laser Ablation
l   Intra/extra fascial veins treated
l   Excellent for SSV (surgery difficult)
l   Minimum 2-3 mm diameter VV’s
l   Patient friendly
l   Safe

Pre Rx                              3 months                      12 months                  2 yrs

Ulcer pre Rx                             3mths post EVLA                        6 months post Rx

Benefits
l   Physiologic result
l   High efficacy and safety
l   No upper size limit veins treatable
l   Popular with patients
l   No scars, no downtime
l   1470nm … less power, less side effects

 DIMED offers the 1470nm portable diode laser which is with small size, high quality and mainteness easy charactors

Affordable 980nm Diode High Intensity Laser Therapy Equipment Back Treatment Affordable 980nm Diode Laser Back Treatment For Lower Back Pain How Laser Therapy Works All light is composed of photons. 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...

Class IV Lasers in Physical Therapy

Image
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...

Best Diode Laser for Veterinary Laser Surgery

Image
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. BERYLAS                                  ...
