Sinuvertebral Nerve Ablation
Introduction
Sinuvertebral Nerve Ablation (SVNA) is a minimally invasive procedure designed to alleviate chronic discogenic pain by targeting the sinuvertebral nerves, which play a crucial role in transmitting pain signals from the intervertebral discs to the brain.
What is discogenic Pain
Discogenic pain is chronic pain originating from a damaged vertebral disc, often due to degenerative disc disease. This condition occurs when the physical and chemical properties of the disc deteriorate, leading to irritation of nerve receptors in the outer part of the disce limbs. It often worsens with activities that compress the spine, such as sitting or bending, and improves with rest.
Clinical Indications
The SVNA procedure is indicated for patients suffering from chronic low back pain (CLBP) due to degenerative changes in the intervertebral discs. It is particularly beneficial for those who have not responded to conservative treatments such as medications, physical therapy, or epidural steroid injection
Chronic Pain Conditions Treated
Sinuvertebral Nerve Ablation is primarily used to treat chronic pain conditions related to the intervertebral discs, including:
- Discogenic Pain: Chronic pain originating from a damaged vertebral disc.
- Degenerative Disc Disease (DDD): Pain due to the degeneration of intervertebral discs.
- Modic Changes: Inflammation and degeneration of the vertebral endplates, often associated with chronic low back pain.
- Vertebrogenic Pain: Pain originating from the vertebral endplates, where the vertebrae connect to the spinal discs.
Therapeutic value & Effects
Therapeutic Value
Sinuvertebral nerve ablation has shown promising results in reducing pain and improving functional outcomes for patients with discogenic low back pain. Studies have demonstrated significant reductions in pain scores and improvements in disability indices following the procedure.
Duration of Effects
The effects of sinuvertebral nerve ablation can last for several months to years, depending on the individual patient's response to the treatment. Regular follow-up visits are recommended to monitor the patient's progress and address any concerns.
Techniques and Goals
The sinuvertebral nerve ablation procedure involves the use of radiofrequency energy to heat and disrupt the sinuvertebral nerves, thereby blocking the transmission of pain signals. The goal is to provide long-term pain relief and improve the patient's quality of life2.
What to Expect
When a patient comes to the clinic for this procedure, they will undergo a thorough evaluation, including a medical history review, physical examination, and imaging studies to confirm the diagnosis. The procedure itself is performed under local anesthesia, and patients can typically go home the same day.
Procedure Details
The procedure involves the following steps:
- The patient is positioned on their stomach on an operating table.
- A small incision is made in the lower back.
- Using fluoroscopy (real-time X-ray), a thin needle is guided to the target area.
- Radiofrequency energy is applied to heat and ablate the sinuvertebral nerves
Possible Side Effects and Complications
As with any medical procedure, there are potential side effects and complications, including infection, bleeding, and nerve damage. However, these risks are minimal, and the procedure is generally considered safe
