目的:本研究的目的是探讨潜在神经源性肿瘤活检前超声引导神经阻滞的安全性和可行性。
方法:对2017年6月至2022年6月的病历进行回顾性审查,确定了在术前神经阻滞下进行的潜在神经源性肿瘤的超声引导活检。患者人口统计学,活检部位,通过次数,针规,使用镇静剂,病理结果,记录和总结手术并发症。
结果:结构化搜索发现16例患者接受了18例潜在神经源性肿瘤的活检,并在各种上肢和下肢位置使用术前神经阻滞。患者平均年龄为52岁(18-78岁),9名患者(56%)为女性。在16名患者中,10例患者未进行静脉镇静。在使用神经阻滞之前,三名患者无法耐受活检。所有活检都产生了具有13种神经源性肿瘤起源的诊断样品。一名患者报告轻度术后疼痛,经保守治疗后缓解;未报告其他并发症。
结论:在超声引导下对潜在神经源性肿瘤进行活检之前进行神经阻滞是一种安全可行的技术。需要进一步研究以确定神经阻滞可以减轻术中疼痛并减少或消除活检期间镇静的程度。
OBJECTIVE: The aim of this study is to investigate the safety and feasibility of ultrasound-guided nerve block prior to biopsy of potentially neurogenic tumors.
METHODS: A retrospective review of the medical record from June 2017 to June 2022 identified ultrasound-guided biopsies of potentially neurogenic tumors that were performed with a pre-procedural nerve block. Patient demographics, biopsy site, number of passes, needle gauge, use of sedation, pathology results, and procedural complications were recorded and summarized.
RESULTS: The structured search found 16 patients that underwent biopsies of 18 potentially neurogenic tumors with the use of a pre-procedural nerve block at a variety of upper and lower extremity locations. Average patient age was 52 (range 18-78) and 9 patients (56%) were female. Of the 16 patients, 10 were performed without intravenous sedation. Three patients were unable to tolerate biopsy until a nerve block was used. All biopsies yielded a diagnostic sample with 13 of the tumors neurogenic in origin. One patient reported mild postprocedural pain which resolved with conservative treatment; no other complications were reported.
CONCLUSIONS: Nerve block prior to ultrasound-guided biopsy of potentially neurogenic tumors is a safe and feasible technique. Further study is needed to determine the extent to which nerve block can decrease intra-procedural pain and reduce or eliminate the need for sedation during biopsy.
