About VenaBlock®
Answers to the most common questions from healthcare professionals and patients about cyanoacrylate vein closure treatment.
What is VenaBlock and how does it work?
VenaBlock® is a cyanoacrylate-based vein closure system that permanently seals varicose veins using medical-grade adhesive. Unlike laser or radiofrequency ablation, VenaBlock uses no heat. The adhesive is delivered through a catheter and polymerizes (hardens) in less than 1 second upon contact with blood, instantly sealing the vein. The procedure is performed under ultrasound guidance with only local anesthesia at the access site.
Is VenaBlock better than laser vein treatment (EVLA)?
VenaBlock offers several advantages over endovenous laser ablation (EVLA) and radiofrequency (RF) ablation:
• No tumescent anesthesia required (fewer needle sticks)
• No risk of thermal nerve damage
• No compression stockings needed post-procedure
• Same-day return to normal activities
• 73% less post-procedural pain
Clinical studies show comparable 96% success rates with significantly improved patient comfort.
How long does the VenaBlock procedure take?
The VenaBlock procedure typically takes 15-30 minutes per leg. Bilateral (both legs) treatment can often be completed in a single session. Patients can walk immediately after treatment and return to normal activities the same day. No overnight hospital stay is required – it's a true outpatient procedure.
What is the success rate of VenaBlock treatment?
VenaBlock has demonstrated excellent long-term results in clinical studies:
• 96.4% anatomical success rate at 12 months
• 92.8% closure rate at 5 years
• 94.2% patient satisfaction score
• Only 0.3% DVT incidence rate
These results are comparable to or better than thermal ablation methods.
Do I need to wear compression stockings after VenaBlock?
No, compression stockings are not required after VenaBlock treatment. This is one of the key advantages over thermal ablation methods, which typically require 1-2 weeks of compression therapy. Patients can return to their normal wardrobe immediately after the procedure.
Is VenaBlock safe? What are the side effects?
VenaBlock has an excellent safety profile with minimal side effects. The DVT (deep vein thrombosis) incidence rate is only 0.3%. Since no heat is used, there is no risk of thermal nerve damage or skin burns. Some patients may experience:
• Mild inflammation along the treated vein (phlebitis)
• Temporary skin discoloration
• Minor bruising at the access site
These effects are typically mild and resolve within days to weeks.
What types of veins can be treated with VenaBlock?
VenaBlock is designed for treating superficial truncal veins in the lower extremities, including:
• Great Saphenous Vein (GSV) – the most commonly treated vein
• Small Saphenous Vein (SSV)
• Accessory saphenous veins
• Anterior accessory saphenous veins
The system is available in 4F, 5F, and 6F catheter sizes to accommodate various vein diameters.
