Spider Naevi

Introduction to Spider Naevi

Spider Naevi, also known as spider angiomas or spider veins, are small, red vascular lesions that often feature a central arteriole with radiating capillaries, resembling a spider’s web. They are commonly found on the face, neck, and upper part of the trunk.

Causes and Risk Factors

Several factors can contribute to the development of Spider veins:

• Hormonal Fluctuations: They are often associated with pregnancy and can be influenced by hormonal changes.
• Liver Conditions: Individuals with liver diseases, such as cirrhosis, may develop spider naevi due to increased levels of circulating oestrogen.
• Medications: Certain medications, including oral contraceptives, can increase the risk of developing spider veins.
• Genetics: A family history of spider naevi can increase an individual’s likelihood of developing them.

Identification and Symptoms

Spider veins are characterised by their distinctive spider-like appearance. They are bright red, can be flat or slightly raised, and may blanch when pressure is applied. While they are usually painless, their appearance can cause cosmetic concerns for some individuals.

Modern Treatment Approaches

Several treatments are available for those who wish to reduce or eliminate the appearance of Spider viens:

• Electrolysis: This involves using a fine needle to apply an electric current to the blood vessels, causing them to coagulate and eventually fade.
• Sclerotherapy: A solution is injected into the spider naevi, causing the vessels to shrink and fade over time.

Conclusion

Spider Naevi are benign vascular lesions that can appear due to various causes. While they are harmless, many seek treatment for cosmetic reasons. With modern techniques, it’s possible to significantly reduce or even eliminate their appearance.
