The aim of this study was to describe the technique of percutaneous paravertebral endoscopic decompression for the treatment of far-out syndrome and to analyze the early clinical results of this technique.
From April 2021 to June 2023, a retrospective study was conducted on patients with far-out syndrome who underwent percutaneous paravertebral endoscopic decompression at Hospital of Chengdu University of Traditional Chinese Medicine. The Visual Analogue Scale (VAS), Oswestry Disability Index (ODI), and modified MacNab criteria were utilized for the assessment of leg pain, quality of life, and clinical efficacy, respectively. Clinical outcomes were assessed at the day before surgery, 1 day, 1 month, 3 months, 6 months after surgery, and the last follow-up. Meanwhile, the incidence rate of foraminal stenosis, surgery time, and complications were recorded for comprehensive evaluation.
This study included a cohort of 16 patients, with a mean age at the time of surgery of 70.94 ± 4.04 years. The average duration of symptoms was 10.81 ± 5.13 months, while the mean follow-up period lasted for 16.69 ± 5.84 months. The results revealed significant improvements in VAS scores and ODI scores at each time point following the operation (P < 0.05). According to the modified MacNab criteria, excellent or good outcomes were observed in 15 cases (93.70%). Four patients presented with postoperative numbness, which was effectively alleviated through conservative treatment. One case with a fair outcome exhibited residual radicular symptoms.
The current technical report presents a successful treatment strategy for far-out syndrome, demonstrating promising preliminary efficacy and safety.
本研究旨在描述经皮椎旁内镜减压术治疗远外侧综合征的技术，并分析该技术的早期临床效果。
对2021年4月至2023年6月在成都中医药大学附属医院接受经皮椎旁内镜减压术的远外侧综合征患者进行回顾性研究。采用视觉模拟评分法（VAS）、Oswestry功能障碍指数（ODI）和改良MacNab标准分别评估腿痛、生活质量和临床疗效。在术前1天、术后1天、1个月、3个月、6个月及末次随访时评估临床结局。同时记录椎间孔狭窄发生率、手术时间和并发症情况进行综合评价。
本研究纳入16例患者，手术时平均年龄为70.94±4.04岁。症状平均持续时间为10.81±5.13个月，平均随访时间为16.69±5.84个月。结果显示术后各时间点VAS评分和ODI评分均有显著改善（P<0.05）。根据改良MacNab标准，15例（93.70%）患者疗效为优或良。4例患者术后出现麻木，经保守治疗有效缓解。1例疗效为可的患者有残留神经根症状。
本技术报告为远外侧综合征提供了一种成功的治疗策略，显示出有前景的初步疗效和安全性。
