The aim of this study was to evaluate the effectiveness of computed tomography (CT)-guided infiltration in the treatment of Arnold's neuralgia.
A retrospective study included 31 patients suffering from Arnold's neuralgia and having undergone a total of 45 CT-guided infiltrations of the greater occipital nerve (GON), in a proximal site (emergence of the GON, technique 1, n = 24) or in two proximal sites (emergence of the GON and at the site of the first bend of the GON drawn by the GON, technique 2, n = 21). Infiltration was considered to be effective when pain relief was equal to or greater than 50% for at least 1 month.
There was no significant difference between the two techniques regarding immediate pain relief effect (53.3% for technique 1 vs. 60.5% for technique 2, p = 0.5), but technique 2 yielded better persistence of pain relief effect (p = 0.01), leading to a significantly higher percentage of effective infiltrations with technique 2 (p = 0.03).
Infiltrations carried out in a single site yield results that are comparable to those previously published. Infiltrations in two sites provide significantly better results and should now be preferred to other single-site techniques in order to reduce the rate of failure or recurrence of Arnold's neuralgia.
本研究旨在评估计算机断层扫描（CT）引导下浸润治疗阿诺德神经痛的有效性。
一项回顾性研究纳入了31例患有阿诺德神经痛且总共接受了45次CT引导下枕大神经（GON）浸润的患者，浸润部位为近端（GON穿出点，技术1，n = 24）或两个近端部位（GON穿出点以及由GON绘制的GON第一个弯曲处，技术2，n = 21）。当疼痛缓解至少持续1个月且缓解程度等于或大于50%时，浸润被认为是有效的。
两种技术在即时疼痛缓解效果方面无显著差异（技术1为53.3%，技术2为60.5%，p = 0.5），但技术2在疼痛缓解效果的持续性方面更好（p = 0.01），导致技术2的有效浸润百分比显著更高（p = 0.03）。
在单一部位进行的浸润产生的结果与先前发表的结果相当。在两个部位进行浸润可提供明显更好的结果，为降低阿诺德神经痛的失败率或复发率，现在应优先于其他单部位技术。
