Dear Ken, I'm going to have a surgery with my varicose vain on Friday, it will be actually pulled out, but just found out you can have a laser treatment, instead. It sounds less drastic but whats the actual advantages and  disadvantages of both, surgery and laser treatment ? Thank you

Hello H - good to hear from you again - laser treatment sounds like a less
invasive and more convenient way of dealing with the problem especially if you have found
someone who is familiar with the technique and has already had good results. However it
is still somewhat early days and you may have to regard yourself as a bit of a guinea pig. Pulling out (stripping) the vein is the traditional method for significant varicose veins and normally produces good results.
I am copying some information from an unbiased source which may be helpful as you make up
your mind - it mentions heat treatment as well as laser treatment but obviously
references to heat treatment should be ignored.
Hope this helps - I am very interested to know what you decide and also how you get on.

Do they work?

We don't know for sure. These newer treatments for varicose veins aren't done as often as
surgery or injections. There isn't much research to say whether or not they work.

What are they?

Surgery is the only way to get rid of varicose veins completely. But it's a big operation
and there are risks. Surgeons have been looking at other ways to remove varicose veins
that may be easier and quicker than traditional surgery. One of these ways is closing the
vein with heat.

Your surgeon can use heat to close your varicose veins in several ways.

Radiofrequency ablation

In this method, your surgeon puts a thin instrument into your vein. The instrument
produces energy, which heats and seals off your vein. This is called radiofrequency
ablation. Surgeons usually use this method for larger varicose veins.

If you're having treatment for a varicose vein in your leg, your surgeon will:1

Make a small cut above or below your knee, depending on the area being treated
Put the heating device into your vein or thread it through a very thin tube (called a
catheter) and then into your vein.
Heat the device and pull it back slowly through your vein.
The heated device seals your vein while your surgeon pulls it out.

Laser treatment

In this method, doctors use a laser to seal off veins.

Your doctor will thread a thin tube (called a catheter) through a small hole in your skin
into your vein.
They will then place a laser in the tube, and the intense light from the laser will heat
your vein and make it close up.
You'll be given a local anaesthetic to numb the area, so you'll be awake but you won't
feel any pain.
Your doctor will then slowly remove the laser, and your vein will seal off as the laser
comes out.
Laser treatment is quick. It takes just 90 seconds to treat a 30-centimetre (12-inch)
length of vein.2

The National Institute for Health and Clinical Excellence (NICE) is the government
organisation that advises doctors about treatments. NICE says that both radiofrequency
ablation and laser treatment are safe enough and work well enough for use in the NHS. But
we don't know the long-term effects of these treatments. You should talk to your doctor
about the risks and benefits of having one of these treatments.2 3

How can they help?

Radiofrequency ablation seems to work about as well as having surgery to strip out
varicose veins. In one study, 14 in 15 people having radiofrequency ablation were happy
with the way their legs looked afterwards.4

Radiofrequency ablation may be less painful than having veins stripped out by surgery.
But we're not sure. There hasn't been much research.5

We don't know how well laser therapy works compared with other treatments for varicose
veins. There haven't been any good-quality studies.

Why should it work?

Usually veins carry blood upwards through your legs to your heart. They have one-way
valves in them that keep blood flowing in the right direction.

In varicose veins, the valves don't work properly. So blood slips backwards into the
vein, causing your vein to bulge. To learn more, see What are varicose veins?

Closing up your varicose vein with heat or lasers means blood can no longer flow through
that vein, and it flows through your other veins instead. So blood no longer pools in
your varicose veins, causing them to bulge.

Can it be harmful?

Radiofrequency ablation does sometimes have side effects.

Between 6 in 100 to 7 in 100 people who have radiofrequency ablation get burns.3 But as
doctors get better at using this technique, burns should become less of a problem.

Some people get an unusual feeling in their legs after having radiofrequency ablation,
especially if they've had surgery on a vein below the knee.3

About 2 in 100 to 3 in 100 people get inflammation in the vein.3 Doctors call this
phlebitis. If you have phlebitis, your veins can become swollen. They feel hard and warm,
and look red. The area can feel sore.

More serious problems, such as having clots in your veins (deep vein thrombosis) or a
blockage in your lungs (pulmonary embolism), happen in less than 1 in 100 people.3

You're likely to get some pain and bruising after having laser treatment.2 But this will
go away after a few weeks. Some people also get inflammation after having laser
