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.
Chemodenervation and nerve blocks are other forms of neurolysis. [1] Neurotomy may refer to the application of heat (as in radiofrequency nerve lesioning), chemical ablation, or freezing of sensory nerves with the intent of a longer term (months or years) ablation or partial denervation of one or more peripheral nerves, usually to relieve ...
Radiofrequency ablation or lesioning, also known as rhizolysis, can be used to give longer lasting relief by destroying the nerves that supply the facet joint (medial branch nerves). [9] Current guidelines as per the International Spine Intervention Society require two successful medial branch blocks before progressing to a radiofrequency ablation.
Neuroablation can be performed with chemical neurolysis or radiofrequency ablation. These techniques are often used on the medial branch nerves to treat low back pain and have been applied to the superior cluneal nerves. The use of phenol has been noted to relieve pain for up to 9 months but may not completely resolve symptoms. [5]
Facet joint injections are used to alleviate symptoms of Facet syndrome. [1] The procedure is an outpatient surgery, so that the patient can go home on the same day. It usually takes 10–20 minutes, but may take up to 30 minutes if the patient needs an IV for relaxation. [ 2 ]
Degeneration or damage to the facet joints can often lead to facet joint syndrome, which can be both diagnosed and treated by image-guided injection of anesthetics. [39] Facet joint block is a minimally invasive procedure in which a physician uses fluoroscopy or CT imaging to guide the placement of an injection of medication into a facet joint ...
Nerve block or regional nerve blockade is any deliberate interruption of signals traveling along a nerve, often for the purpose of pain relief. Local anesthetic nerve block (sometimes referred to as simply "nerve block") is a short-term block, usually lasting hours or days, involving the injection of an anesthetic, a corticosteroid, and other agents onto or near a nerve.
Catheter ablation is a procedure that uses radio-frequency energy or other sources to terminate or modify a faulty electrical pathway from sections of the heart of those who are prone to developing cardiac arrhythmias such as atrial fibrillation, atrial flutter and Wolff-Parkinson-White syndrome.
