Varicose vein surgery involves treating the swollen, lumpy and dark blue or purple veins that lie under the skin in your legs (varicose veins).
You will meet the surgeon carrying out your procedure to discuss your care. It may differ from what is described here as it will be designed to meet your individual needs.
Varicose veins don't get better without treatment and are often treated with surgery. Ligation and stripping and phlebectomy are common techniques but alternative techniques such as sclerotherapy, endovenous laser and radiofrequency ablation are now commonly used too.
There are a number of different techniques for varicose vein surgery, which are described below. Your surgeon will explain your options to you and help you decide which treatment is best for you.
This is a technique that is often used to remove the long or short saphenous veins in your legs. Your surgeon will make two cuts about 4cm long – one in your groin and the second in your lower leg either close to your knee or ankle. Your surgeon will tie off the faulty vein (this is called ligation) through the cut in your groin to stop blood flowing through it. He or she will then use a thin flexible wire to carefully pull (strip) out the varicose vein through the cut in your knee or ankle.
Ligation and stripping is done under general anaesthesia. This means you will be asleep during the procedure.
Your surgeon will make a small cut just near your varicose vein and will insert a fine plastic tube called a catheter into your vein. He or she will use an ultrasound scan to guide the catheter to the correct position. Your surgeon will then pass a fine laser or a probe through the catheter and inside your vein. He or she will use this to heat the wall of the vein, which will destroy it. Your body will absorb the dead tissue. See our frequently asked questions for more information.
These procedures are performed under local anaesthesia. This completely blocks pain from the area and you will stay awake during the procedure.
Sclerotherapy involves injecting a chemical into your varicose veins. This will damage the veins and close them. Liquid sclerotherapy is often used to treat smaller veins below the knee. For larger veins, foam sclerotherapy is used. After you have the procedure, your doctor may put a compression bandage over the area or you may be asked to wear compression stockings for up to two weeks.
Studies have shown that this treatment is effective at treating varicose veins in the short-term. However, the long-term benefits of this treatment aren't yet known. The procedure also has potentially serious complications (problems that occur during or after the procedure), which although uncommon, include stroke or damage to nerves. It’s important to tell your surgeon if you have had deep vein thrombosis (DVT) in the past and to discuss the safety of ultrasound guided foam sclerotherapy.
The procedure is performed under local anaesthesia.
Phlebectomy is used to remove the smaller surface veins that lie under your skin. Your surgeon will make small cuts (which can be as little as 1mm long) on your leg and use hooks to pull out the affected veins. This procedure may be done with ligation and stripping or with the endovenous laser and radiofrequency or sclerotherapy techniques. It can be used on its own if you're only having surface veins treated.
Transilluminated powered phlebectomy is another option to remove the smaller surface veins but isn’t commonly used. In this procedure, your surgeon will make small cuts in your leg and place a tiny light under your skin to highlight the affected veins. Your surgeon will use a special suction device with blades and cut and remove the varicose vein by suction. As with phlebectomy, this procedure may be done with another procedure or on its own to treat surface veins alone.
Currently, there is limited evidence for the long-term benefits of this treatment. As with any operation, it is important to discuss the safety of this procedure with your surgeon.
Your surgeon will explain how to prepare for your procedure. For example, if you smoke, you will be asked to stop as smoking increases your risk of getting a chest and wound infection, which can slow your recovery.
If you're having a general anaesthetic, you will be asked to follow fasting instructions. This means not eating or drinking, typically for about six hours before your operation. However, it's important to follow your anaesthetist's advice.
Your surgeon will discuss with you what will happen before, during and after your procedure, and any pain you might have. This is your opportunity to understand what will happen, and you can help yourself by preparing questions to ask about the risks, benefits and any alternatives to the procedure. This will help you to be informed, so you can give your consent for the procedure to go ahead, which you may be asked to do by signing a consent form.
The operation may take between 30 minutes and two hours, depending on the type of veins that will be removed, the technique your surgeon uses and whether one or both of your legs are being treated.
You will need to rest until the effects of the anaesthetic have passed. If you have had a local anaesthetic, it may take several hours before the feeling comes back into your leg(s). Take special care not to bump or knock the area. You may need pain relief to help with any discomfort as the anaesthetic wears off.
You may need to wear compression stockings on your legs to help maintain circulation for up to two weeks after your operation.
Your nurse will give you some advice about caring for your healing wounds before you go home. You will be given a date for a follow-up appointment.
General anaesthesia temporarily affects your co-ordination and reasoning skills, so you must not drive, drink alcohol, operate machinery or sign legal documents for 24 hours afterwards. You will need to arrange for someone to drive you home. Try to have a friend or relative stay with you for the first 24 hours.
The amount of time your dissolvable stitches will take to disappear depends on the type of stitches you have. However, for this procedure, they should usually disappear in about four weeks. Usually, if you have the endovenous laser and radiofrequency techniques, you won’t have any stitches. If you have non-dissolvable stitches you will need to attend an outpatient appointment to have these taken out.
It usually takes up to two weeks to make a full recovery from varicose vein surgery but this will depend on the type of surgery you have and whether you have one or both of your legs treated. The time it takes to recover also varies between individuals, so it's important to follow your surgeon's advice.
If you need pain relief, you can take over-the-counter painkillers such as paracetamol or ibuprofen. Always read the patient information that comes with the medicine and if you have any questions, ask your pharmacist for advice.
You should be able to drive around two days after your operation. If you’re in any doubt about driving, contact your motor insurer so that you’re aware of their recommendations, and always follow your surgeon's advice.
There are some important things to remember while recovering from having varicose vein surgery.
As with every procedure, there are some risks associated with varicose vein surgery. We haven’t included the chance of these happening as they are specific to you and differ for every person. Ask your surgeon to explain how these risks apply to you.
Side-effects are the unwanted but mostly temporary effects you may get after having the procedure. Side-effects of varicose vein surgery include:
Complications are when problems occur during or after the procedure. Complications of having varicose vein surgery can include the following.
Although many people won't need any further treatment after surgery, it's possible varicose veins may re-occur.
