What is CLaCS (Cryo-Laser and Cryo-Sclerotherapy) and how has it evolved?
CLaCS combines transdermal laser, sclerotherapy, and skin cooling to treat spider veins and reticular veins. Its evolution by 2026 includes refined laser parameters and optimized cryotherapy application, enhancing precision and minimizing discomfort during procedures. This integrated approach allows for more effective treatment of complex vascular networks.
CLaCS, or Cryo-Laser and Cryo-Sclerotherapy, represents a sophisticated approach to treating superficial varicose veins and spider veins. This technique synergistically uses three components: a transdermal laser, a sclerosing agent injection, and intense skin cooling. The laser targets the vein, while cryotherapy (skin cooling to sub-zero temperatures) protects the skin and reduces pain. Immediately following the laser, a sclerosing solution is injected into the same vein, causing it to close. At SoulClin in Belo Horizonte, Dr. Rafael Costa utilizes CLaCS to provide a highly precise and comfortable treatment experience. This method is particularly effective for small to medium-sized veins, offering superior aesthetic results and reduced side effects compared to isolated techniques. Recent updates in 2026 focus on advanced laser wavelengths and improved cryo-devices, further optimizing patient safety and treatment efficacy.
How does conventional sclerotherapy work for varicose veins?
Conventional sclerotherapy involves injecting a sclerosant solution directly into varicose or spider veins, causing them to collapse and fade over time. This established method effectively treats various vein sizes, promoting their absorption by the body. Its principles remain fundamental, with ongoing research refining solution concentrations and injection techniques.
Conventional sclerotherapy is a widely used and effective treatment for various types of varicose veins and spider veins. The procedure involves injecting a chemical solution, known as a sclerosant, directly into the affected vein. This solution irritates the lining of the vein, causing it to swell, stick together, and eventually close off. Over time, the treated vein turns into scar tissue and fades from view as the body naturally absorbs it. Depending on the size and type of vein, the sclerosant can be used in liquid form or as a foam. Foam sclerotherapy is often preferred for larger veins or when treating multiple veins simultaneously. Dr. Rafael Costa, an expert in Angiology and Vascular Surgery, often employs conventional sclerotherapy for suitable cases at SoulClin, ensuring patient comfort and optimal results. This technique offers a minimally invasive alternative to surgery for many patients.
What are the key differences between CLaCS and conventional sclerotherapy in 2026?
The primary distinction lies in CLaCS's integrated approach of laser and cryotherapy alongside sclerotherapy, offering enhanced precision and patient comfort. Conventional sclerotherapy relies solely on chemical injection. By 2026, CLaCS is increasingly favored for its ability to target veins more effectively, especially smaller, superficial ones, while minimizing side effects.
Understanding the differences between CLaCS and conventional sclerotherapy is crucial for choosing the most appropriate treatment. While both aim to eliminate unwanted veins, their methodologies and patient experiences vary significantly. CLaCS offers a multi-modal approach, integrating laser energy and extreme cold with the sclerosing agent. This combination allows for precise targeting and reduced discomfort during treatment. Conventional sclerotherapy, conversely, relies solely on the chemical action of the sclerosant. At SoulClin, Dr. Rafael Costa evaluates each patient's specific condition to recommend the best technique. Based on more than 15,000 procedures performed, the choice often depends on vein size, location, and individual patient factors.

What do recent guidelines say about patient selection for CLaCS and sclerotherapy?
Recent 2026 guidelines emphasize tailored patient selection, considering vein size, location, and patient preference. CLaCS is often preferred for superficial telangiectasias and reticular veins due to its precision and reduced pain. Conventional sclerotherapy remains a versatile option, especially for larger varicosities or when a simpler approach is suitable.
Patient selection is paramount in achieving successful outcomes for varicose vein treatment. Updated guidelines from 2026, supported by vascular societies, underscore the importance of individualized treatment plans. For instance, CLaCS is highly recommended for patients with visible spider veins (telangiectasias) and reticular veins that are often resistant to isolated sclerotherapy. The combination of laser and cryotherapy allows for better visualization and targeting. For larger varicose veins, or those with underlying saphenous reflux, other treatments like Endolaser (EVLT) might be considered first, followed by sclerotherapy for residual smaller veins. Dr. Rafael Costa at SoulClin in Belo Horizonte conducts a thorough clinical evaluation, including a duplex scan, to accurately diagnose and determine the most effective treatment strategy. This ensures that each patient receives care optimized for their specific venous condition, aligning with the latest advancements in Angiology.
What are the recovery expectations and long-term outcomes for both treatments?
Recovery from both CLaCS and conventional sclerotherapy is generally quick, often involving minimal downtime and compression stocking use. Long-term outcomes are positive, with significant improvement in vein appearance and symptoms. Regular follow-ups are crucial to manage any recurrence, aligning with best practices emphasized in 2026 vascular care.
Patients undergoing either CLaCS or conventional sclerotherapy can expect a relatively smooth recovery. Most individuals can resume normal daily activities almost immediately. Compression stockings are typically recommended for a period after the procedure to aid healing and improve results. Minor bruising, swelling, or temporary skin discoloration at the treatment sites are common but usually resolve within a few weeks. Strenuous exercise should be avoided for a few days. Long-term outcomes for both treatments are generally excellent, with a high degree of patient satisfaction regarding aesthetic improvement and symptom relief. However, it is important to understand that new spider veins or varicose veins can develop over time due to genetic predisposition or lifestyle factors. Therefore, regular follow-up appointments with a vascular specialist like Dr. Rafael Costa are essential for monitoring and addressing any new concerns, ensuring sustained vascular health. The goal at SoulClin is to provide comprehensive care for Chronic Venous Insufficiency.
