This article compares two approaches side by side to clarify how they differ in principle and practice. Device selection depends on vein anatomy, diameter, tortuosity, and clinician preference, and is always determined on a case-by-case basis by the treating physician. As a medical device manufacturer, INVAMED develops technologies in this area; the information here is educational and not medical advice.
Background: Varicose Veins and Chronic Venous Insufficiency
Chronic venous insufficiency (CVI) sits on the same disease spectrum and can present with aching, heaviness, swelling, skin changes, and in advanced cases venous ulceration. Device selection depends on vein anatomy, diameter, tortuosity, and clinician preference, and is always determined on a case-by-case basis by the treating physician. Modern management has shifted from open surgical stripping toward catheter-based endovenous techniques that are typically performed under local anesthesia in an outpatient setting.
Vein glue (cyanoacrylate) vs Radiofrequency ablation: Key Differences
Cyanoacrylate closure is non-thermal and typically avoids tumescent anesthesia, whereas radiofrequency ablation is thermal and generally requires it. The adhesive approach can mean less peri-procedural injection discomfort, while thermal ablation has the longest track record and extensive outcome data. Both aim to permanently close the refluxing vein; reported medium-term closure rates for each are high in the published literature and in INVAMED's own figures. Selection depends on vein diameter, tortuosity, cost considerations, and patient factors, and is decided by the treating clinician.
How INVAMED Supports Both Approaches
Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.
Key Considerations
- Graduated compression is commonly used after ablation to support the treated limb, per clinician protocol.
- Vein diameter, depth, and tortuosity influence whether a thermal or non-thermal device is more suitable.
- Because varicose disease reflects an ongoing tendency, follow-up and surveillance help detect new reflux early.
Frequently Asked Questions
Does INVAMED offer both thermal and non-thermal vein devices?
Yes. INVAMED's venous line includes thermal systems (LaserBLOCK laser and ThermoBLOCK radiofrequency) and a non-thermal cyanoacrylate system (VenaBLOCK).
Who decides which vein treatment is appropriate?
Only a qualified clinician can decide, based on ultrasound mapping and individual assessment; this article is educational and not a treatment recommendation.
Clinical and Technical Context
Sealing the refluxing axial vein is intended to reduce the venous hypertension that drives symptoms and visible tributaries. Device figures cited by INVAMED describe studied performance and should not be read as individual guarantees. The main practical appeal is patient comfort during the procedure and avoidance of heat-related nerve irritation. All INVAMED venous devices are intended for use by trained clinicians under ultrasound guidance and per the IFU. INVAMED's portfolio includes small-vein RF ablation needles and the VeinOFF treatment agent as adjuncts to its main ablation platforms. Accurate duplex ultrasound mapping before treatment is central to identifying the source of reflux and planning device placement. Because varicose disease reflects an ongoing tendency, follow-up and surveillance help detect new reflux early. Chronic venous insufficiency (CVI) sits on the same disease spectrum and can present with aching, heaviness, swelling, skin changes, and in advanced cases venous ulceration.
