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.

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...

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4月23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.

2025年3月24日 · C2 DRGs were characterized with bulk, single nucleus, and spatial RNA sequencing technologies from 22 patients. Through a comparative analysis to published datasets of the lumbar DRG and TG, neuronal clusters identified in both TG and DRG were identified in the C2 DRG. Therefore, our study definitively characterizes the molecular composition of ...

2025年3月30日 · Neurons in the dorsal root ganglion (DRG) receive and transmit sensory information from the tissues they innervate and from the external environment. Upper cervical (C1-C2) DRGs are functionally unique as they receive input from the neck, head, and occipital cranial dura, the latter two of which are also innervated by the trigeminal ganglion (TG).

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.

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.

2016年8月5日 · Conventional heat radiofrequency lesioning of the dorsal root ganglion (DRG) remains controversial owing to the potential risk of deafferentation pain. For this reason, DRG pulsed radiofrequency lesioning (PRFL), as a nondestructive neuromodulation technique, would be more attractive for chronic pain management [1–6].

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 ...
