At The London Vein Treatment Centre, we understand that thread veins can prove to be very embarrassing as they become prominent and visible on the skin.

Thread veins are in some ways a smaller version of varicose veins. They are closer to the surface of the skin. However, unlike varicose veins, they do not have the twisted/bulging appearance which is caused by a breakdown in the vein structure. They are therefore not uncomfortable and not considered a medical issue or risk.

They are often visible on the surface of the thighs, backs of knees, calves and ankles. While this might be considered an aesthetic issue, there are practical consequences. For example, many patients report that they are forced to wear uncomfortable tights or trousers in summer for fear of their thread veins being commented on.

What Causes Leg Thread Veins?

  • The top causes of thread veins is heredity – where the condition runs in families and certain people are just more prone to experiencing them
  • Exposure to severe weather conditions can cause the veins to rise to the surface and appear ‘broken’
  • Hormonal changes in women like pregnancy and menopause can trigger thread veins in the legs
  • Age is a factor, as leg thread veins tend to be more prevalent in those over the age of 40+

thread veins
1

Dark purple thread veins and broken veins are common on the thighs. These are perfect for treatment with sclerotherapy injections or ND Yag laser.

Reddy blue thread veins are a common problem behind the knee area.

Thread veins are also commonly found on the calves, where the network of red/blue visible veins can cause great aesthetic concerns.

Types of Leg Thread Veins

Different vein presentations on the leg require different approaches to achieve the clearest results.

Leg Area / Vein Type Common Appearance Best Recommended Treatment
Thighs & Calves
(Larger networks)		 Dark purple or blue branches, often deeper in the skin. Sclerotherapy Injections
(Direct internal closure)
Behind the Knee
(Delicate clusters)		 Reddish-blue networks, highly visible when walking. Combination Therapy or Sclerotherapy
Ankles & Lower Leg
(Fine lines)		 Tiny, bright red broken capillaries closer to the surface. Nd:YAG Laser Treatment
(Precision targeting)

Sclerotherapy vs. Laser

Which is Right for Me?

  • Sclerotherapy:
    Best for medium-to-large blue/purple leg veins. A tiny needle introduces a solution that closes the vein. Highly cost-effective for large areas.
  • Nd:YAG Laser Treatment:
    Best for tiny, fine red veins or patients who are needle-phobic. Uses light energy to collapse the capillary walls safely through the skin.
