Here at Croydon Day Hospital we offer treatment for a wide range of vascular conditions including: varicose veins, aneurysms, venous disease, leg ulcers and diabetic foot disease.
We use the latest technologies to treat varicose veins including VNUS and EVLT as alternatives to the more invasive litigation and stripping surgery. Your vascular surgeon will discuss with you your options and help you to decide which is best for you.
Radiofrequency ablation, also known as the VNUS closure procedure is a minimally invasive treatment for varicose veins. It uses radiofrequency energy (electricity) to heat, collapse and seal off problem veins.
Under local anaesthetic and using ultrasound guidance your vascular surgeon will insert a catheter (thin tube), through a small incision, into your varicose vein. Electricity is then delivered to a heating element in short pulses, heating and contracting the collagen in the vein walls until they shrink and shut down, a process known as ablation. The vein is treated in segments starting at your groin end and gradually moving down towards the incision.
Once the whole vein is ablated your blood flow will automatically reroute through healthier adjacent veins, restoring your circulation and reducing swelling. The ablated vein will turn to scar tissue and eventually be absorbed by your body.
Endovenuous laser therapy (EVLT), also known as endovenous laser ablation (EVLA), uses laser treatment to seal targeted varicose veins. EVLT is typically carried out under local anaesthetic and a catheter is inserted into your varicose vein using ultrasound guidance. Laser is then passed through the catheter to the top of your varicose vein to heat it up and close it. Treatment moves along your vein until the whole vein has been closed.
Once the entire vein is closed your blood will reroute to nearby healthy veins. The treated vein will become scar tissue and eventually your body will absorb it.
