Termocoagulação por radiofrequência do gânglio trigêmeo guiada por TC vs guiada por fluoroscopia para neuralgia trigeminal idiopática
Termocoagulação por radiofrequência do gânglio trigêmeo guiada por TC versus guiada por fluoroscopia para neuralgia trigeminal idiopática: um ensaio clínico randomizado
The goal of this clinical trial is to compare the effectiveness and safety of CT-guided versus fluoroscopy-guided trigeminal ganglion radiofrequency thermocoagulation (TG-RFT) in treating idiopathic trigeminal neuralgia (TN) in adults aged 18 and older.
The main questions it aims to answer are:
- Does CT-guided TG-RFT provide better pain relief compared to fluoroscopy-guided TG-RFT?
- What are the differences in medication consumption between the two methods?
- What are the procedure-related adverse events for both methods?
Investigators will compare CT-guided TG-RFT to fluoroscopy-guided TG-RFT to see if one method is superior in treating idiopathic TN.
Participants will:
- Undergo either CT-guided or fluoroscopy-guided TG-RFT procedure
- Be monitored post-procedure and followed up at 1, 3, and 6 months for pain relief, medication consumption, and adverse events.

Descrição detalhada
This randomized controlled trial aims to compare the efficacy and safety of CT-guided versus fluoroscopy-guided trigeminal ganglion radiofrequency thermocoagulation (TG-RFT) in patients with idiopathic trigeminal neuralgia (TN). Idiopathic TN is characterized by severe, recurrent facial pain, and radiofrequency thermocoagulation is a common interventional treatment option.
Participants eligible for this study will be adults over 18 years old, diagnosed with idiopathic TN based on the International Headache Society criteria, experiencing pain for at least six months with a numeric rating scale (NRS) score greater than 6 despite medical treatment.
Exclusion criteria include vascular compression of the trigeminal nerve by MRI, secondary causes such as multiple sclerosis, trigeminal autonomic cephalalgias, dental or temporomandibular joint pathologies, previous interventional procedures or surgery for TN, coagulopathy, use of antiaggregants and anticoagulants, cardiac pacemaker, renal-hepatic insufficiency, psychiatric illness, malignancy, or infection at the injection site or systemic infection.
Participants will be randomly assigned to either the CT-guided or fluoroscopy-guided RFT group using a computer-generated randomization list. Both procedures will be performed under aseptic conditions with appropriate monitoring and anesthesia. The CT-guided RFT will use real-time CT imaging for needle placement and monitoring, while the fluoroscopy-guided RFT will use fluoroscopic imaging.
The primary outcome measure is pain relief, assessed at 1-, 3-, and 6-months post-procedure using the Numeric Rating Scale (NRS) and Visual Analog Scale (VAS). Secondary outcomes include changes in medication consumption assessed by the Medication Quantification Scale III (MQS III) and the recording of procedure-related adverse events.
This study aims to provide valuable insights into the comparative effectiveness and safety of CT-guided versus fluoroscopy-guided TG-RFT in managing idiopathic TN, potentially guiding future clinical practice.

Pain Relief - Numeric Rating Scale (NRS)
Prazo: Baseline, immediately post-procedure, 1 month, 3 months, and 6 months post-procedure.
|
The primary outcome measure will be the level of pain relief, as assessed by the Numeric Rating Scale (NRS), a 0-10 scale where 0 represents "no pain" and 10 represents "worst possible pain.". Pain levels will be recorded at baseline (pre-procedure), immediately post-procedure, and at 1-, 3-, and 6-months post-procedure. |
Baseline, immediately post-procedure, 1 month, 3 months, and 6 months post-procedure.

|
Pain Relief - Visual Analog Scale (VAS)
Prazo: Baseline, immediately post-procedure, 1 month, 3 months, and 6 months post-procedure.
|
Additionally, pain relief will be assessed by the Visual Analog Scale (VAS), a continuous scale ranging from 0 to 100 mm, where 0 represents "no pain" and 100 represents "worst possible pain." Pain levels will be recorded at the same time points: baseline, immediately post-procedure, and at 1-, 3-, and 6-months post-procedure. |

Medication Consumption
Prazo: 6 months post-procedure

Procedure-related Adverse Events
Prazo: Immediately post-procedure, 1 month, 3 months, and 6 months post-procedure
|
Adverse events related to the interventions will be systematically recorded to evaluate the safety profile of CT-guided versus fluoroscopy-guided trigeminal ganglion radiofrequency thermocoagulation (TG-RFT). Adverse events will be monitored and recorded immediately post-procedure and during follow-up visits at 1, 3, and 6 months. |
