This document discusses the pathophysiology of venous telangiectasias and potential accessory treatments. It begins by noting the unknown pathophysiology and lack of improved treatment results from new methods. It then explores various aspects of telangiectasia types, locations, interactions with other veins, and relations to perforating veins. The author proposes that telangiectasias can be resolved by improving drainage and reducing filling gradients, similar to treating varicose veins. Various techniques using hydrostatic pressure, Doppler, and postural changes are suggested to identify filling and draining veins and gradients. Guidelines for sclerotherapy timing and use of compression stockings are provided to help prevent new telangiectasia formation ("matting").
2. New investigative methods and new technological devices
have not improved teleangiectasia treatment results
Unknown Physiopathology

Cellulite + teleangiectasias = no match found
Telangiectasia + color doppler = no match found
Telangiectasia + duplex scan = 2 matches found ( 1993)
3. Unsolved problems
• Different types of teleangiectasias ( varying
disposition similar to tree foliage, foliage up, foliage
down )
• Location in the leg
• Interactions with reticular veins ( filling or
draining )
• Role of the perforator veins
• Relations with the saphenous system

5. Every Telangiectasic tree has a filling and a draining pressure
gradient
Like in a varicose system, I can resolve the
telangiectasia by improving the drainage and reducing
the filling gradient.
First , I must determine which reticular vein fills and which
drains
6. • With the folliage up and reticular vein down
• With folliage down and reticular vein up
• With reticular veins mixed with teleangectasias
Disposition of the telangiectasic tree :
Telangiectasia
Reticular Vein Telangiectasia
Reticular Vein
7. Use of Hydrostatic pressure and Doppler can help us to
detect the direction of the draining gradient
The hypothesis suggested by graviational law is:
•When the reticular vein is up, it is a filling vein
•When it is down, it is a draining vein
Filling Vein
Draining Vein
Disposition of the telangiectasic tree :
8. Foliage Down Telangiectasia - postural changes
and function of the reticular vein above
• Hydrostatic gradient changes its direction
and from a filling gradient becomes a
draining gradient
9. In this situation the inversion of the gradient is slowed by the tortuosity of the
reticular network.
Foliage Down Telangiectasia - postural changes
and function of the reticular vein above
10. 1) The reticular vein does not have a defined source
2) The reticular vein originates from a refluxing point
Foliage Down Telangiectasia - Origin of the
reticular network
1) Whithout escape point 2) From Point P
11. In every case, the sclerotherapic
treatment of the reticular vein leads to
telangiectasic reduction.
If this filling vein originates
from the drainage of other
telangectasic ones or from
cellulite, its suppression
increases the risk of matting
occurrence
12. The filling vein of a foliage down telangiectasia
may also be the draining vein of a critical zone
… Attention !!!
3) Emergence of matting
1) Sclerotherapy of the reticular v.
2) Reduction of the telangiectasias
13. If the reticular vein originates from an escape point,
the situation must be investigated and treated
correctly .

16. This means that, in the specific case of
foliage down telangiectasia, careful
investigation must be performed with a
high resolution ultrasound 12-18 Mhz
probe and transillumination.

22. Haemodynamic patterns of the re-entry perforator
• Valsalva negative
• No systolic flow
• Diastolic inflow
Usually the re-entry perforator is in
the leg , where the muscolar pump
activity is efficient.
23. The draining gradient in Foliage Up Telangiectasia
We have to respect the drainage system. Its closure leads to
the risk of matting
24. The filling gradient in Folliage Up Telangiectasia
No reticular vein above
the telangiectasia
Telangiectasia origin
due to cellulite tissue
25. The fybrosis and compact structure of cellulite
tissue creates an obstacle to venous drainage from
the skin surface to the hypoderma and deep tissue.

Obstacle to
Physiologic drainage
26. Telangiectasias represent a compensatory system
around this obstacle.
Their suppression creates a new obstacle to the
venous flow that leads to an increase of venous
pressure and to the realization of a new drainage.
This is possibly one of the pathogenetic
mechanisms of matting (*)

Foliage up Telangiectasia represents a vicarious circle
28. Elimination of the foliage up telangiectasia
corresponds to the suppression of a vicarious circle
Bad result due to excess of treatment
The more veins I close, the more new veins re-
form, because I cannot modify the residual venous
pressure

29. Therefore, the problem is not to improve the efficacy of
the sclerotherapic treatment, but to promote a new
invisible drainage, and to prevent matting.

Is the treatment of
cellulite possible?
30. Soft sclerotherapy, timing and compression
stockings work together
Sclerotherapy closes ectasic telangectasias and, step by
step, worsens venous stasis in cellulite tissue.
Residual venous pressure tries to find a new drainage
Compression stockings increase tissue pressure and
impede venous stretching and dilation due to increased
lateral pressure .
31. Consequently, step by step, sclerotherapy closes,
nature recreates, and the compression stocking guides.
Timing should be regulated by the restoration of a new
drainage.
Therefore, the draining volume of superficial tissue is
limited by the compression, and new drainage will devolop
where resistance to the flow is lower, for example, away
from the skin.
Soft sclerotherapy, timing and compression
stockings work together
32. Guidelines for a good result according to
these haemodinamic considerations
• Timing of sclerotherapic treatments :1 treatment
every 4 weeks
• Light sclerotherapic agents
• Medical treatment , sistemic draining drug and topic
treatment (Arnica)
• Compression by a 24 mm.Hg elastic stocking for 3
weeks (*)
• Stop treatment at the right time ( before matting !! )
