Glue Closure: Non-Surgical Varicose Vein Treatment

Spider veins, those small red, blue, or purple veins that appear on the legs and face, can be a cosmetic concern and sometimes cause discomfort. While traditional treatments like sclerotherapy and laser therapy have been used to address this issue, a newer technique known as CLaCS (Cryo-Laser and Cryo-Sclerotherapy) is gaining traction for its effectiveness and minimal invasiveness. Let’s explore what CLaCS is and why it’s becoming a popular choice for treating spider veins.

What is Sclerotherapy?

Sclerotherapy is a procedure used to treat varicose veins and spider veins, both of which are associated with poor venous circulation and can contribute to venous insufficiency. During the procedure, a solution is injected into the affected veins, causing them to collapse and eventually be absorbed by the body. The blood is then rerouted through healthier veins, improving overall circulation.

How Sclerotherapy Helps:

Improved Blood Flow:
By closing off damaged veins, sclerotherapy improves circulation in the legs, preventing blood from pooling in the veins. This reduces the risk of developing blood clots, which can form due to stagnant or slow-moving blood.
Preventing Post-Thrombotic Syndrome:
In patients with a history of DVT, sclerotherapy can help treat veins that have been damaged by previous clotting episodes, reducing the chance of developing post-thrombotic syndrome. This condition is characterized by chronic leg pain, swelling, and venous ulcers, which occur due to poor blood flow after a clot has damaged the vein walls.
Relieving Symptoms of Chronic Venous Insufficiency:
Chronic venous insufficiency (CVI) is a condition where veins struggle to return blood to the heart efficiently, often leading to varicose veins and an increased risk of DVT. Sclerotherapy targets the faulty veins responsible for CVI, relieving symptoms and reducing the risk of future clots.
Minimally Invasive with Quick Recovery:
One of the key advantages of sclerotherapy is that it is minimally invasive and requires little downtime, making it an attractive option for patients looking to improve vein health and reduce clotting risk without undergoing major surgery


Ablation Therapy:

A Long-Term Solution for Vein Health Ablation is a procedure used to treat varicose veins and other vein disorders. It involves using heat (radiofrequency ablation) or laser energy (endovenous laser ablation, or EVLA) to close off problematic veins. Like sclerotherapy, ablation reroutes blood through healthier veins, improving overall circulation and reducing the risk of blood clots.

How Ablation Helps:

Effective Treatment for Varicose Veins:
Varicose veins are a major contributor to chronic venous insufficiency, which can lead to poor circulation and blood pooling in the veins. Ablation effectively treats large varicose veins, reducing the likelihood of clot formation.
Reducing the Risk of DVT:
By sealing off veins that are not functioning properly, ablation improves blood flow and reduces the potential for blood stagnation, a key factor in clot formation. This is particularly important in patients who are at high risk of DVT due to venous insufficiency.
Preventing Future Venous Complications:
Ablation not only improves current circulation issues but also prevents the development of future venous problems, which may otherwise lead to chronic pain, swelling, and an increased risk of clots.
Minimally Invasive and Long-Lasting:
Ablation is a minimally invasive procedure that can be performed in an outpatient setting. Patients typically experience minimal discomfort and can return to normal activities quickly. The long-term success rate of ablation is high, offering a durable solution for venous issues that can lead to clots.y



By improving circulation and addressing underlying venous insufficiency, these treatments help reduce the risk of blood clots, prevent future complications, and improve overall vein health. While not directly used to treat acute VTE, they are effective in managing the chronic venous problems that increase the risk of clot formation. These minimally invasive procedures provide long-lasting results and contribute to better long-term outcomes for patients at risk of venous thromboembolism.

Can sclerotherapy or ablation treat an active blood clot?

No, sclerotherapy and ablation are not used to treat active or acute blood clots. Acute VTE is managed with medications such as anticoagulants or emergency interventions when required. These procedures are used after stabilization to address abnormal veins that contribute to poor circulation and future clot risk.

How do vein treatments help reduce future clot formation?

+
Damaged or poorly functioning veins cause blood to pool and slow down, which increases the likelihood of clot formation. By closing these faulty veins, sclerotherapy and ablation improve blood flow through healthy veins, reducing stagnation and lowering the risk of future clots.

Are these procedures safe for patients with a previous history of DVT?

+
Yes, when performed after proper evaluation, these procedures are safe for patients with a past history of DVT. In fact, treating damaged veins after a clot can help reduce symptoms and prevent complications such as post-thrombotic syndrome.

What is the role of these treatments in chronic venous insufficiency?

+
Chronic venous insufficiency causes persistent leg swelling, pain, skin changes, and increases clot risk. Sclerotherapy and ablation directly treat the faulty veins responsible for CVI, improving circulation and relieving long-term symptoms.

Can treating varicose veins really lower DVT risk?

+
Yes, treating varicose veins improves venous circulation and reduces blood pooling, which are key contributors to clot formation. While it does not eliminate all DVT risk, it significantly reduces one of the major underlying causes.
