Non-thermal techniques for venous ablation

Hi, this video talks about the non-thermal venous ablation techniques using glue or the mechanico-chemical technique. What are these? Yes, these are non-thermal techniques, so they differ from radiofrequency and laser in that no heat is used. This means that we don't need to do the injections for tumors and anesthesia, which means there's less numbers of needle injections required. How is it carried out? Mechanicochemical one involves injecting a chemical with a catheter which rotates inside the vein which mechanically agitates the lining and makes the chemical more effective. Recovery is very similar to the thermal techniques but can take up to two or three days. In terms of the glue treatment, here a glue is injected which causes the vein to stick together and block the vein. Long-term outcome similar to the thermal techniques intending to cause relief of symptoms, preventing worsening of the venous ulcers and preventing recurrence of venous ulcers. Usually very successful with data up to two years. These techniques are newer, so we don't have as long-term data as the thermal techniques. In terms of risks, wound infection, numbness, bruising, and post-procedural pain, as well as some hyperpigmentation in the area that we treat, secondary to thrombophlebitis, and minor, again, risks would be similar to those with thermal techniques. More serious risks include DVT and pulmonary embolus. Thank you very much for your time.
