ObjectiveTo evaluate the clinical efficacy and safety of CT-guided low-temperature plasma radiofrequency ablation combined with ultrasound-guided stellate ganglion block(SGB) for cervical spondylosis with sympathetic symptoms.

MethodsThe clinical data of 73 patients with cervical spondylosis with sympathetic symptoms were analyzed retrospectively, including 42 patients who underwent low-temperature plasma radiofrequency ablation alone(group A) and 31 patients who underwent low-temperature plasma radiofrequency ablation combined with SGB(group B).The general data, visual analogue scale(VAS), Japanese Orthopaedic Association scores(JOA), sympathetic symptom scores, clinical efficacy and complications were compared between the two groups.

ResultsThere was no significant difference in VAS score, JOA score and sympathetic symptom scores between the two groups before treatment(P>0.05).The VAS scores of group B at 1 and 4 weeks after treatment and the scores of sympathetic symptoms at 1, 4 and 12 weeks after treatment were lower than those of group A(P < 0.05 to P < 0.01), and the JOA scores at 1 and 4 weeks after treatment were higher than those of group A(P < 0.05 and P < 0.01).At 12 weeks after treatment, the overall excellent and good rates of group A and group B were 85.71%(36/42) and 87.10%(27/31), respectively, and the difference of which was not statistically significant (P>0.05).There was no obvious complication in each group.

ConclusionsLow-temperature plasma radiofrequency ablation combined with SGB in the treatment of cervical spondylosis with sympathetic symptoms is helpful to improve patients' symptoms and promote patients' rehabilitation.It has certain clinical value.
