2018年9月21日 · C2 DRG locates on the coverage of bones that passes through the middle part of the atlantoaxial joint, and then it travels between obliquus capitis inferior muscle and semispinalis capitis muscle, continuing as the great occipital nerve. Under the guidance of X-ray or CT, the target is the atlantoaxial joint.

2019年6月27日 · CT provides excellent guidance for C2 DRG injection and radiofrequency ablation and can be combined with procedural CT angiography to highlight vascular anatomy.

2024年3月20日 · While pulsed radiofrequency ablation of the C2 dorsal root ganglion (DRG) is an effective treatment for refractory occipital neuralgia, accessing the C2 DRG remains a clinical challenge even under fluoroscopic guidance. Objective: We aimed to develop an ultrasonographic method for quickly and accurately accessing the C2 DRG.

Objective: To evaluate the efficacy and complications of C2 dorsal root ganglion (DRG) pulsed radiofrequency ablation (RFA) for cervicogenic headache (CEH) and to identify factors related to the outcome of the procedure in this retrospective analysis.

2018年9月21日 · This case report is about a patient who suffered from chronic migraine with occipital pain and was successfully treated with PRF of C2 (axis) dorsal root ganglion (DRG) under ultrasound...

While pulsed radiofrequency ablation of the C2 dorsal root ganglion (DRG) is an effective treatment for refractory occipital neuralgia, accessing the C2 DRG remains a clinical challenge even under fluoroscopic guidance.

The C2 DRG is the principal nerve root that contributes to the greater and lesser occipital nerves, providing an ideal target for ablation, because it only provides sensory innervation. 13,14 Patients should be considered for C2 DRG RFA if they present with cervicogenic headaches and have failed conservative treatment options, including ...

Download scientific diagram | Transducer position and corresponding ultrasound image of C2 DRG. (A) Anatomical diagram of ultrasonic probe placement. (B) Patient’s position and performance of the...

CT-guided injection and radiofrequency ablation (RFA) of the C2 dorsal root ganglion (DRG) is a safe and effective treatment for cervicogenic headache arising from C1-C2 joint arthritis. The C2 nerve root is unique in that it lacks a motor component; RFA can …
