ABSTRACT:
Crippa A.
OBJECTIVES: In combination with usual transdermal therapy at 532 nm
treatment, we have evaluated also 808 nm wave-length laser in intra-extra luminal
procedure for the treatment of teleangectasias. Endolasering with 100 or
200 µm micro optical fibres can cause photothermocoagulation of the vessel
wall thanks to the direct intra-extra venous contact.
In fact, 808 nm being scarcely absorbed by both water and fat tissue, does not
harm surrounding perivenous tissues during photocoagulation. When the firing
becomes from the extravasal side, the first target is the adventitial vasa venarum.
MATERIALS AND METHODS: Since march 2008, 300 patients (270
female, 30 male) presenting tortuous teleangectasias are treated with intra-extra
luminal 808 nm diode Laser (Eufoton, Trieste, Italy). After topical anaesthesia
(EMLA Cream or cryogenic local therapy), a special micro fiber of 100 or
200µm in teleangectasias are inserted intra - extra near the veins wall, using at
the same time a combined skin cooling system during and after treatment. We
differentiate 2 types of teleangectasias treatments.
a. Telangectasias sized from 0,5 mm to 1 mm (blue, violet).
We used a special titanium introducer for 25 G needle to introduce
easily the fiber into the needle. Skin temperature must be controlled
by palpation. The fiber is pushed up where the reflux originates and
