Sclerotherapy is the treatment used in most cases to treat surface veins. This treatment of veins has been in use for over 75 years. Normal routine activities are encouraged after treatment and time off work is usually not required.
Sclerotherapy involves injecting a sclerosing solution with a very fine needle directly into the diseased vein. The solution causes a reaction along the internal wall of the vein, causing it to swell and stick together. As a result the vein no longer fills with blood and will gradually fade over a period of weeks until it becomes barely visible. Depending on size, some veins require several injections for optimal results, but in any one treatment session numerous veins can be injected. Larger underlying veins must be treated first to reduce the chance of recurrence of surface spider veins. An ultrasound will be used to rule out incompetent veins that lead to superficial spider vein development. This procedure requires specialized skills.
Many solutions are available however, "Fibrovein" is the solution preferred by Dr Lekich. This solution is specifically manufactured for sclerotherapy. "Fibrovein" is rapidly broken down after contact with the vein wall and does not circulate through the body as an active solution. The effects of Fibrovein are isolated in its action.
There are definitely certain veins that are required for healthy blood flow in the legs. Abnormal veins though, are unhealthy veins that do not function properly and usually (sometimes for years) haven't been relied upon by the body as part of normal blood circulation. These abnormal veins contain poorly oxygenated blood and subsequent free radicals that cause tissue damage. To compensate for this lack of function, more stress is placed on the deeper veins that can, in certain cases, also become abnormal. Once treated, circulation usually improves in the affected limb.
Abnormal veins are not harvested for by-pass heart grafts.
Although many vessels are injected each treatment session, discomfort
is minimal because of the tiny diameter of the needle. The ankle, foot
and high thigh region may be a little more sensitive, although the pain
experienced is easily tolerable. Some larger injections give a feeling
like a dull ant bite, while most small injections into the veins feel
slightly warm and tingly. You will be lying on the examination table
during this time and changing positions to your side, back and stomach
as needed to access the affected areas.
Anxious patients may require relaxing medications. Dr Lekich will discuss
this with you.
Often larger incompetent vessels underlie superficial veins - this will be assessed using an ultrasound in the initial consultation. If this is the case then the larger veins will be treated first. The smaller, superficial veins may be treated at the same time or may require a subsequent treatment session. Patients that present earlier for treatment generally require fewer treatment sessions
Bruising in the treated area is quite normal and to be expected. Often legs can initially look worse, but this is only temporary. Blood may be trapped in the vein after treatment, forming a lump that becomes tender. These lumps are relieved by small needle aspirates as a routine procedure on your next visit. These lumps are not blood clots, but are a sign that treatment has been successful. The bruises will disappear within 2 to 3 weeks.
Generally, after the recommended number of treatments as per your assessment, as a general rule, patients can expect up to an 80- 90% improvement in treated vessels. Legs may look worse initially from bruising, but this is only temporary. Treated veins will start to fade a few weeks after treatment and continue to fade for up to three months after the last treatment.
Occasionally subsequent sessions are required in particular when the condition is severe and long standing. Sclerotherapy is highly effective in treating abnormal veins however, absolute cosmetic perfection may not be achieved as a result of the progression of new abnormal veins.
Generally, the veins that are treated will not require repeated treatment. Over time however, previously normal veins may progress and develop new changes. If there is an inherent tendency for vein walls to weaken, then these previously normal veins may require treatment in the future. This tendency or predisposition for abnormal veins may affect previously successfully treated veins. Keeping to a healthy diet and weight, regular exercise and limiting time spent in high heel shoes can help minimize the development of new veins.
As with all treatments it is important to be aware of the possible side effects of Sclerotherapy treatment:
Mild to moderate ache in the legs in the first day or two after treatment (relieved by walking and panadol)
Some redness at the injection sites: disappears within a day or two
Brown spots or lines on the skin: these pigmented areas occur due to blood escaping from the treated veins. The brown pigmentation is mostly haemosiderin, a form of iron that is stored in the body and in most cases disappears within a year. Around 5% of patients find that the pigmentation can persist for more than a year - laser can be used to minimize this effect. To reduce this side effect it is advisable not to take iron supplements during the course of treatment and to have trapped blood removed at your follow up appointment.
Tender lumps in the treated vein: this is caused by the trapping of some blood in the injected vessel. These lumps are not blood clots but are a sign that treatment has been effective. They can be alleviated instantly by fine needle aspiration (which is part of the routine treatment) on your next visit.
Matting: this is the formation of fine, closely grouped red blood vessels close to the injection sites of larger vessels. Approximately 16% of patients develop these and they either spontaneously resolve or disappear with injection. Occasionally, some may persist. Poor muscle tone or inability to exercise can increase the prevalence of matting as can a large number of surface veins pre-treatment. Cigarette smoking increases this risk. This effect can be greatly minimized by walking for 45mins daily or substitution low impact aerobics or cycling.
Rarely, small ulcerations can occur at the injection site within 2 weeks of treatment. These can be painful and can be due to either the escape of the sclerosing agent into the surrounding tissues or sensitivity of the tissues to the concentrate of the agent used. Although they can be easily treated, please inform the doctor immediately. These ulcers tend to heal slowly and can leave a small scar. This side effect is more commonly observed in patients who smoke. Overall the risk of this is minimized by a careful treatment approach.
Allergic Reaction: rarely an allergic reaction to a certain sclerosing agent can occur. Although serious, they can be treated instantly by adrenaline injection and antihistamine therapy. Hospitalization in this instance is uncommon. Minor rashes can occur and requires no specific treatment however, please inform the doctor so an alternative solution can be used in your subsequent treatments.
Phlebitis (pronounced "Fle-bite-us"): Inflammation of the treated blood vessels can occur in 1% of patients undergoing sclerotherapy. This condition can be painful but resolves quickly with anti-inflammatory treatment, compression and walking.
Migraine: Patients may experience migraine headache following sclerotherapy. Often migraine symptoms also include visual disturbances. This can be treated with Pannadol or Panadeine – or usual migraine treatment.
Deep Vein Thrombosis: This formation of a clot in a deep vein is a rare occurrence (1 in 2000). This can be minimized by walking and using compression stockings.
Intra-Arterial Injection: Resulting in muscle and skin damage, this complication is extremely uncommon. Use of through ultrasound examination will reduce complications. Dr lekich uses the highest resolution ultrasound to guide treatment to best avoid this rare complication.
There are no known long-term side effects of sclerosing solution
Yes, and it is easy!
