Evidenced-based protocols for fluoroscopically guided LP do not exist. This study analyzed the fluoroscopically guided LP techniques currently used by practicing neuroradiologists.
An anonymous Web-based survey was e-mailed to members of ASNR. The results were compiled and tabulated on a spreadsheet.
A total of 577 neuroradiologists completed the survey. Most neuroradiologists perform fluoroscopically guided LPs with the patient in the prone position by using a 22-ga needle at the L2-L3 or L3-L4 intervertebral space. The OP measurement technique is quite variable. Only a minority of patients are rotated to the left LD position for OP measurement. Most neuroradiologists observe patients for 1-2 hours after the procedure and require strict bed rest.
Most neuroradiologists have similar protocols for thecal sac puncture. Normative adult OP data exist only for the LD position, and the accuracy of prone OP measurements is not known. We found that the OP measurement technique is not consistent and a standard protocol is warranted.
目前不存在基于循证的荧光引导下腰椎穿刺术（LP）方案。本研究分析了目前神经放射科医生实际应用的荧光引导下 LP 技术。
我们向美国神经放射学会（ASNR）成员发送了匿名的网络调查。结果以电子表格形式进行了汇总和制表。
共有 577 名神经放射科医生完成了这项调查。大多数神经放射科医生让患者采取俯卧位，在 L2-L3 或 L3-L4 椎间隙使用 22 号针进行荧光引导下 LP。腰椎穿刺术（OP）测量技术差异较大。只有少数患者在进行 OP 测量时被旋转到左侧卧位。大多数神经放射科医生在术后 1-2 小时观察患者，并要求严格卧床休息。
大多数神经放射科医生在脊髓穿刺方面有相似的方案。只有 LD 位置有成人 OP 的正常参考数据，而俯卧位 OP 测量的准确性尚不清楚。我们发现 OP 测量技术并不统一，需要制定一个标准方案。
