Minimally invasive varicose vein treatment
A thin catheter or needle closes the faulty vein from the inside, so blood moves to healthier veins. Options include endovenous laser or radiofrequency ablation, foam sclerotherapy and medical adhesive (glue). Most are done under local anaesthesia as day procedures.
Who it may suit
- Varicose veins with aching, swelling, skin changes or ulcers
- Veins confirmed on duplex ultrasound to have faulty valves
- People who want a shorter recovery than vein stripping surgery
What happens
- Duplex ultrasound to map the veins and find the faulty segments
- Choice of method by a vascular specialist
- Treatment under local anaesthesia, often under an hour
- Compression stockings and walking afterwards, then a follow-up scan
Usually 1 to 3 days.
Canadian care includes these treatments. Coverage depends on the province and clinic, and many people wait or pay privately.
How it works
Varicose veins form when valves in leg veins stop working well and blood pools. They can cause aching, swelling, itching, skin changes and sometimes ulcers. Many people only want treatment for how the veins look, and cosmetic treatment is often not publicly funded.
The NHS describes endothermal ablation, with laser or radiofrequency energy, as usually the first choice. A catheter is placed into the vein, and heat closes it. Foam sclerotherapy injects a chemical foam, and is used when ablation is not suitable. Glue closes the vein with medical adhesive, often without needing stockings. Surgery to tie and strip the vein is now used when the simpler procedures are not suitable.
Compared with stripping, these methods use local anaesthesia and have faster recovery. They are not permanent for everyone. New veins can appear over the years, and the underlying tendency remains. The procedures are not usually recommended during pregnancy. This is a mature, widely available treatment, so the main question is usually access, timing and cost rather than whether a technique exists only abroad.
Potential advantages
- Local anaesthesia and same-day discharge are usual
- Return to normal activity often within a few days
- No large incision, so scars are small
- Several methods allow the treatment to be matched to the vein
- May be combined with a stay for recovery and rest during a trip
What to prepare for a specialist review
- Any previous venous duplex ultrasound reports
- History of leg swelling, ulcers or blood clots
- Current medicines, especially blood thinners
- Photographs of the legs showing symptoms and skin changes
- Allergy history, especially to local anaesthetic
- Details of previous vein procedures
Questions to ask the treating team
- Which vein segments need treatment, and which method do you advise?
- What is the chance the veins return, and what then?
- Will I need compression stockings, and for how long?
- What are the risks of clots, nerve irritation or skin staining?
- Can I fly home safely, and when?
Things to know. Risks include bruising, pain, skin staining, nerve irritation and, rarely, blood clots. Veins can return over time. We are still confirming which Chinese hospitals currently offer this to international patients.
Why an introduction matters
Many of China’s leading specialists work in busy public hospitals without international patient offices. They rarely answer enquiries from abroad directly, and a file sent without an introduction often goes unread. Cases usually reach them through people they already know and trust. Our team on the ground makes that introduction, presents your case properly in Chinese, and follows up until you have an answer.
