Spider Veins
and Reticular Veins

Spider veins are the tiny red or blue veins that may appear anywhere on the body, but more often on the legs, ankles, face, chest, or abdomen. They are extremely common. Spider veins may appear to be short, seemingly unconnected lines, each about a hair’s width, or they may resemble a spider web or tree with branches. In medical terms spider veins are called telangiectasias and usually occur in association with larger dilated blood vessels (often blue / green in colour) called reticular veins. Dilated blood vessels may cause aching especially with prolonged standing.

What causes spider veins?

Spider veins are often a flow-on effect of varicose veins in nearby blood vessels. When the damaged section of vein (varicose vein) fills with blood and swells to its capacity, the overflow of blood creates tiny spider veins close to the skin. This is why it is important to treat the underlying cause, and not just the spider veins that can be seen on the skin surface.

Are spider veins dangerous?

Generally speaking, the answer is no. However, if spider veins are a result of underlying venous disease, then the underlying condition causing the spider veins must be treated, as it could lead to further complications if left untreated.

Do you need these veins?

Although dilated blood vessels do carry blood they are not efficient and are often not necessary to the circulatory system. The body will have already established an alternative route for the blood to travel back more efficiently to the heart. Thus, they can be treated without a negative effect on circulation. Treatment will actually improve circulation.

There is an approximately 80% chance for a greatly improved appearance with direct vision sclerotherapy, depending on the severity of the problem. Treatment will also usually relieve any symptoms caused by the veins.

Spider veins appearing in the lower leg, ankle or foot can be a sign of serious varicose vein disease. Spider veins in those areas are almost always fed by a larger internal vein that is malfunctioning, and could lead to further complications if left untreated.

How do phlebologists classify the severity of venous disease?

In the past it has been tricky for phlebologists and health professionals to define vein disorders because of the range and severity of symptoms. By creating the CEAP venous disease classification system, discussion of conditions and treatments is standardised across the world. Read more about the CEAP classification system.

How We Treat Spider Veins and Reticular Veins

Ultrasound Guided Sclerotherapy

Ultrasound Guided Sclerotherapy is a highly specialised procedure involving injecting a sclerosant solution into the abnormal veins using ultrasound guidance, causing the vein wall to collapse. The veins dissolve and disappear as the body gradually absorbs them.

Direct Vision Sclerotherapy

The gold standard treatment of spider veins is direct vision sclerotherapy, also known as standard sclerotherapy or microsclerotherapy. It involves the injection of a special solution through a tiny needle into the spider veins, which causes them to collapse and eventually harden over.

AccuVein Vein Viewing System

AccuVein illuminates veins that may be otherwise undetectable with the naked eye. This improves accuracy of treatment and allows the phlebologist to confirm visually that the treatment has been successful.

Medicare Rebate & Costs

The cost of treating varicose veins depends on severity of the veins as well as which treatment is used. We discuss these costs in detail at your initial consultation.


A Medicare rebate is claimable on all varicose vein procedures, except the most superficial spider veins.
