The
VENCLOSE™ radiofrequency ablation system is the latest evolution in minimally invasive vein treatment. Like its predecessor, ClosureFast™, it uses controlled heat to gently seal abnormal veins. The procedure is performed under local anaesthesia on an outpatient basis, meaning no hospital stay and rapid recovery.
What to Expect
- A tiny incision is made below the knee.
- The VENCLOSE™ catheter is guided into the vein using ultrasound.
- Each 2.5–10 cm segment of vein is treated with a 20‑second burst of radiofrequency energy.
- The heat causes the vein wall to shrink and seal shut.
- An average 45 cm vein can be treated in just a few minutes.
Unlike older vein stripping surgery or laser ablation, the catheter delivers
uniform, consistent heat at temperatures below 120°C. This results in less bruising, less pain, and faster recovery.
Frequently asked questions
What is the Venclose procedure?
Venclose uses radiofrequency energy to heat and seal varicose veins under local anaesthetic.
What are the differences and similarities between Venclose and ClosureFast?
Both Venclose and ClosureFast use radiofrequency energy to seal varicose veins under local anaesthetic. The technique, recovery, and outcomes are very similar. The main difference is the catheter system used — Venclose offers variable length treatment options, while ClosureFast uses a fixed segment approach. In practice, both achieve excellent results with rapid recovery.
Is Venclose painful?
The procedure is performed under local anaesthetic. Patients usually feel only mild warmth or pressure.
How long does Venclose take?
Treatment typically lasts 45–60 minutes per leg, plus preparation and observation time.
How long is recovery after Venclose?
Patients walk immediately after treatment and resume normal activities within 24 hours.
Are Venclose results permanent?
Treated veins do not return, but new varicose veins can develop over time. Follow‑up helps maintain long‑term results.
