89% of People with Thread Veins Have an Underlying Leg Vein Problem

Thread veins on the legs are a common occurrence. They affect an estimated 70% of women and a significant proportion of men. Research shows that over 89% of people with thread veins have an underlying leg vein issue, often hidden varicose veins. This means thread veins are more than a cosmetic concern.

At Vein Solutions in Chester, we specialise in diagnosing and treating both thread veins and the conditions that cause them.

Thread Veins

Thread veins are small, dilated veins visible on the skin’s surface, appearing as red, blue or purple lines. They may form a single strand or a fan-shaped cluster and are typically less than a millimetre wide. Although they are often thought of as “broken veins”, they are fully functioning veins connected to the deeper venous network.

Under a microscope, thread veins reveal healthy vein walls lined with and containing muscle cells. This proves they are not burst vessels but small superficial veins that have become enlarged.

Causes of Thread Veins

Thread veins form due to a combination of skin type and underlying venous conditions. They affect all skin tones and can appear in any adult. Family history plays a role, with some people genetically predisposed. Hormonal changes during pregnancy or menopause can also make veins more visible.

They are not caused by crossing your legs, wearing tight clothes or taking hot baths. Severe trauma, such as a road accident or crush injury, may trigger their appearance.

The most common cause, however, is venous reflux, or “hidden” varicose veins. In these cases, blood flows downwards under gravity, stretching and enlarging the small surface veins until they become visible.

Recognising The Symptoms

Thread veins are usually apparent to the naked eye. They may be mistaken for bruises that don’t fade or for skin conditions like eczema. Although many people experience no discomfort, some report aching, tenderness or itching, particularly when standing. These symptoms often suggest deeper vein involvement.

Diagnosing Thread Veins

An initial assessment involves careful observation. A handheld Doppler can be used for a basic check. For a more accurate diagnosis, a duplex ultrasound scan maps the veins and detects any hidden varicose veins or reflux. Identifying and addressing the underlying issue is crucial for achieving long-term results.

Conditions Often Confused With Thread Veins

Skin discolouration caused by venous eczema or haemosiderin staining can resemble thread veins, especially near the ankles. Psoriasis and dermatitis may also resemble clusters of veins. Bruises can temporarily mimic thread veins but tend to fade within weeks, unlike true thread veins, which persist or worsen.

Treating Underlying Vein Conditions

Effective treatment starts with the cause. If hidden varicose veins are identified, they are treated first using:

• Radiofrequency ablation
• Endovenous laser ablation
• Ultrasound-guided foam sclerotherapy
• Ambulatory phlebectomy
• Transluminal perforator occlusion
• Coil embolisation for pelvic veins

Traditional vein stripping is no longer recommended, as it carries a high risk of recurrence and can lead to the formation of new thread veins.

Treating Thread Veins

Once any underlying problem is addressed, the surface veins can be treated. Microsclerotherapy is the gold standard for leg thread veins. A sclerosant solution is injected directly into the visible veins, destroying their walls so the body can absorb them. This also affects the connected network of small veins.

Patients wear graduated compression stockings for up to two weeks after treatment to prevent blood pooling. Results develop gradually over three months, with skin often continuing to improve for up to a year.

Other treatments, such as intense pulsed light, laser, and electrolysis, may be suitable for very small veins or facial veins, but are less effective for thread veins on the legs.

Specialist Care Matters

Because over 89% of people with thread veins have an underlying problem, only a qualified vein specialist should carry out assessment and treatment. Without addressing deeper vein issues first, thread vein treatments are likely to fail or require repeated sessions.

At Vein Solutions, we provide thorough assessments, including duplex ultrasound scans when necessary, to ensure each thread vein treatment plan addresses both the appearance and the underlying cause.
