Question 1

What is VenaBlock and how does it work?

Accepted Answer

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 polymerizes in less than 1 second upon contact with blood, instantly sealing the vein.

Question 2

Is VenaBlock better than laser vein treatment (EVLA)?

Accepted Answer

VenaBlock offers several advantages over EVLA: no tumescent anesthesia required, no risk of thermal nerve damage, no compression stockings needed post-procedure, same-day return to normal activities, and 73% less post-procedural pain. Clinical studies show comparable 96% success rates with significantly improved patient comfort.

Question 3

How long does the VenaBlock procedure take?

Accepted Answer

The VenaBlock procedure typically takes 15-30 minutes per leg. Bilateral treatment can often be completed in a single session. Patients can walk immediately after treatment and return to normal activities the same day.

Question 4

What is the success rate of VenaBlock treatment?

Accepted Answer

VenaBlock has demonstrated excellent long-term results: 96.4% anatomical success rate at 12 months, 92.8% closure rate at 5 years, 94.2% patient satisfaction score, and only 0.3% DVT incidence rate.

Question 5

Do I need to wear compression stockings after VenaBlock?

Accepted Answer

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.

Question 6

Is VenaBlock safe? What are the side effects?

Accepted Answer

VenaBlock has an excellent safety profile with minimal side effects. The DVT 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, temporary skin discoloration, or minor bruising.

Question 7

What types of veins can be treated with VenaBlock?

Accepted Answer

VenaBlock is designed for treating superficial truncal veins including Great Saphenous Vein (GSV), Small Saphenous Vein (SSV), accessory saphenous veins, and anterior accessory saphenous veins. The system is available in 4F, 5F, and 6F catheter sizes.
