Radiofrequency ablation is a minimally invasive procedure used in the treatment of varicose veins. It is an alternative to the traditional stripping operation. Under ultrasound guidance, a radiofrequency catheter is inserted into the abnormal vein and the vessel treated with radio-energy, resulting in closure of the involved vein.
Varicose veins are unlikely to be caused by crossing the legs or ankles. [17] Less commonly, but not exceptionally, varicose veins can be due to other causes, such as post-phlebitic obstruction or incontinence, venous and arteriovenous malformations. [18] Venous reflux is a significant cause. Research has also shown the importance of pelvic ...
The CHIVA and the stripping methods are equivalent regarding recurrence of varicose veins, but the CHIVA method may slightly reduce nerve injury and hematoma. The CHIVA method is also equivalent to either radio frequency ablation or endovenous laser therapy regarding recurrence and side effects. [1]
Endovenous thermal ablation (EVTA) by radiofrequency or laser is a safe and effective treatment of refluxing great saphenous veins [7] (GSVs) and has replaced traditional high ligation and stripping in official recommendations of various leading Vascular Societies in the United States and the United Kingdom.
Sclerotherapy is one method for the treatment of spider veins, varicose veins (which are also often treated with surgery, radiofrequency, and laser ablation), and venous malformations. In ultrasound -guided sclerotherapy, ultrasound is used to visualize the underlying vein so the physician can deliver and monitor the injection.
Local anaesthetic endovenous surgery using the thermoablation (endovenous laser ablation or radiofrequency), perforator closure (TRLOP) and foam sclerotherapy showed an 85% success rate of healing, with no recurrence of healed ulcers at an average of 3.1 years, and a clinical improvement in 98% in a selected group of venous leg ulcers.
