Varicose
Veins
Varicose
veins are large veins of the leg that become incompetent and lose the
function of their valves. As a result blood pools backwards into these
veins and causes them to dilate engorge and become visible. They are usually
the underlying cause of many smaller spider veins as well as the increased
venous pressure spills out into the small little blood vessels called
capillaries and causes them to engorge. The traditional treatment for
this problem involved using ultrasound technology to first identify where
the incompetence is and identify the specific vein or valves causing the
problem. Once determined, the next step is to simply surgically make small
incisions in the leg and strip these veins out. This procedure involves
the use of anesthetic and involves small surgical scars to find and remove
the vein. Post operatively compression garments have to e worn to help
prevent recurrence and improve healing.
EVLT
is a much newer method of varicose vein treatent and is done much differently
than traditional vein stripping . Once the isolated problem vein is identified.
A small single needle is inserted into the leg vein to enter it and a
fibre is passed up to the vein using special imaging equipment. The vein
is then burned out from inside out with a laser at the tip of the fibre.
The advantage of this procedure is that there are no incisions commonly
associated with striping and the procedure can be performed under local
anesthetic only.
