1470 Wavelength Endovenous Ablations

The new wave in Endovenous Ablation

In 1989, Puglisi and his colleagues of the School of Malan (Milan) firstly reported at the IUP Congress in Strasbourg, the use of endovenous Laser to treat varicose saphenous veins.

VNUS Closure

FDA Approval March 1999

Compared favorably to Vein Stripping

Laser Ablation Saphenous Vein

FDA approval Jan 2002

Diode Lasers

• Mechanism of action haemogloblin absorption.

• 810 • 940• 980• Similar in results, complication rates,

post operative pain

980 Wavelength Laser vs. VNUS Closure

• 980 laser

• Better results• Lower

Complications• Cost effective to

perform• Simple procedure

• VNUS Closure

• Less postoperative pain

• More published literature to support use.

Disadvantage Lasers

• More post procedure pain

1370 Laser

• Introduced 2005

• Mechanism of action more water absorption

• Result: less post operative pain

1470 Laser

• Biolite Tech

• Better water absorption than previous wavelength lasers

• Single use Radial Fiber

• When a narrow (collimated) beam of light passes through a substance, the beam will lose intensity due to two processes: The light can be absorbed by the substance, or the light can be scattered (i.e., the photons can change direction) by the substance. Just looking at the narrow beam itself, the two processes cannot be distinguished. However, if a detector is set up to measure light leaving in different directions, or conversely using a non-narrow beam, one can measure how much of the lost intensity was scattered, and how much was absorbed.

Thermalite 1470

• Bare tip fiber can be re-used

• Same results

• Cost effective

My Experience

• 2900 Endovenous Ablations from

• Feb 2003 - present.

• 472 endovenous ablations with the 1470 wavelength laser Oct 1, 08 - Oct 30, 09.

• 37 patients treated with Thermalite Laser

Findings

• 472 ablations

• 1 Failure

• No DVT

• Pain ranged 1-2 on a 10 point scale

• Patient could resume normal activity immediately.

• 1470 Wavelength• Better results• Lower Complications• Cost Effective• Simple procedure• Less Postoperative

Pain

• VNUS Closure• More published
