Telangiectasia treatment with the copper vapor laser Yachroma-Med
The term telangiectasia originated from three Latin
words: tel, angio, ectasia which denote tip, vessel, enlargement
respectively. Telangiectasias can be classified into three large
groups: “spider” or “star”, linear and arborizing telangiectasias.
A“spider” telangiectasia develops in children and
teenagers. It rear occurs in adults. A “spider” telangiectasia is
looked as a large main vessel with smaller “legs” around it.
On the photos you can see the linear and
the arborizing telangiectasia, which looked as a tree. This forms consist
of the vessels of similarly diameters. Leaner and arborizing
telangiectasia usually develops in adults.
Telangiectasias localize as a rule on face and legs.
Diameters of the ectatic vessels are from 0.1 to 1 mm on the face and from
0.1 to 3 mm on the legs.
The most patients, who come to clinics of dermatology
and aesthetic surgery, are patients with telangiectasias. Telangiectasia
is term for ectatic vessels of skin, which are located on face and neck or
on legs, in about of 60% and 20% of cases respectively.
About 30 % of fare skin population suffer from the
telangiectasias.The most common factor in occurrence of facial
telangiectasia is weakness of the vessel walls due to chronic sun
exposure. Genetic predisposition, liver disease, surgical trauma,
radiation therapy, chronic steroid use, deep chemical peeling of the face
may also play a role.
Methods of removing
telangiectasias may be selective and non selective. Some years ago a common
method was electrocautery. Electrode may equally destroy ectatic vessel and
adjacent normal tissue. Thus scars, hipo- and hiper- pigmentation may occur
after electrocautery.Most physicians consider that
non-selective methods are not suitable for the vascular and pigmented skin
lesions removing in case of facial location.
Selective laser coagulation is based on the concepts of
selective photothermolysis. Abnormal vessels selectively absorb laser light
and warmed. The vessel temperature increases to 60 – 70 Grad C causing the
abnormal vessels destruction. Adjacent tissue far less absorbs light of
“vascular” laser and don’t injuring. Thus light of “vascular” laser
may selectively destroy of abnormal tissue. The treatment is accurate as in
microsurgery. Radiance of “vascular” laser must have the characteristics
to provide the selective destruction of telangiectasias.
Effectiveness of the treatment depends of the laser
radiation parameters. Such parameters are
One of the best “vascular” laser is a copper vapor laser which can
provide the optimal combination of treatment parameters. For the copper
vapor laser “Yahroma-Med” (manufactured by P.N. Lebedev Physics
Institute, Moscow, Russia) great investigation work have been fulfilled to
determine the parameters, mode and schemes of the treatment of vascular
lesions and telangiectasias in particular. Articles and The Methodology
(Edited by Russian State Medical University) became the results of this
work.
To appreciate the results of telangiectasia removing two criteria are
used:
Effectiveness, Lack of complications.
Main features of using the copper vapor laser “Yahroma-Med" for
the successive treatment of telangiectasias are
-
shot exposure time provided by mechanical shutter,
-
laser light spot, which according to size of vessels,
-
steady light spot on the patient skin
-
some untreated area around every treatment point.
Adult patients tolerate the treatment of
telangiectasias with the copper vapor laser “Yahroma-Med” without
anesthesia. Local anesthesia can be required for the most sensible
patient. The treatment with other “vascular” laser available on the
market is more painful. The patients suffer no pain after the procedure.
Middle erythema can occur during two hours after the
treatment. After the copper vapor laser treatment scabs can be noted along
treatment vessels can be noted. They spontaneously resolve during 3 to 7 days.
However many physicians using Yahroma-Med choose such laser parameter that
scabs can’t be noted at all. On photos 1 and 2 you can see the patients
before and a day after one treatment session with Yahroma-Med.
Complete or almost complete clearance achieved in 90% of patients.
Telangiectasias on cheeks are usually easy to treat. Telangiectasias of
nasal alae are more complicated for treatment and required particular
caution. Some patients with telangiectasias of nasal alae may be resistant
to the treatment (about 4%).
Abnormal vessels disappear during the treatment. Most abnormal vessels
disappeared after one treatment but not all vessels. Appearance of the
patients notably improved (photo 1 and 2). Many patients satisfied by the
results of one treatment. However two or tree treatments may be require
for removing all ectatic vessels.
New ectatic vessels can began to appear in some years if the patient
predisposed to telangiectasia. In the beginning they may be easy removed
by laser. If the patient avoid the factor, which play a role in occurrence
of telangiectasias, ectatic vessels may not appear at all.
