Background:

Lumbar puncture (LP) is a common diagnostic and therapeutic procedure.
Traditional landmark-based LP can have variable success rates and potential complications.
Fluoroscopic guidance offers real-time visualization during needle insertion.

Purpose of the Study:

To provide a comprehensive overview of fluoroscopically guided lumbar puncture (LP).
To detail the specific indications, procedural techniques, associated risks, and benefits of using fluoroscopy for LP.
To serve as a guide for clinicians performing or considering this imaging modality.

Main Methods:

Review of existing literature and procedural guidelines for fluoroscopically guided LP.
Description of patient preparation, C-arm positioning, and needle insertion techniques under fluoroscopy.
Discussion of potential complications and strategies for their mitigation.

Main Results:

Fluoroscopic guidance allows for precise needle placement in the lumbar thecal sac.
It can improve success rates, particularly in patients with difficult anatomy.
Benefits include reduced procedural time and potentially fewer complications compared to landmark techniques.

Conclusions:

Familiarity with fluoroscopically guided LP enhances procedural workflow and success rates.
This technique can minimize complications, improving patient outcomes.
Fluoroscopic guidance is a valuable tool for optimizing lumbar puncture procedures.
