Foraminal stenosis complicating retained broken epidural needle tip -A case report-.

Area of Science:

• Pain Medicine
• Neurosurgery
• Anesthesiology

Background:

• Lumbar epidural anesthesia is a common treatment for chronic pain conditions like lumbar radiculopathy and spinal stenosis.
• Complications from epidural nerve blocks, though infrequent, can range from transient to permanent.
• No prior reports exist of a broken epidural needle tip fragment retained in the lumbar facet joint.

Purpose of the Study:

• To present the first reported case of foraminal stenosis resulting from a retained epidural needle tip in the lumbar facet joint area.
• To highlight a rare but significant complication associated with lumbar epidural procedures.

Main Methods:

• Case report detailing a patient who developed foraminal stenosis.
• Review of the clinical presentation, diagnostic imaging, and management of a retained epidural needle fragment.
• Discussion of the potential mechanisms leading to stenosis.

Main Results:

• A patient developed symptomatic foraminal stenosis after a lumbar epidural procedure.
• Imaging confirmed a retained epidural needle tip fragment within the lumbar facet joint area.
• The retained fragment was implicated as the cause of the developing stenosis.

Conclusions:

• Retained epidural needle fragments, though rare, can lead to serious complications such as foraminal stenosis.
• This case underscores the importance of meticulous technique and awareness of potential complications during lumbar epidural anesthesia.
• Further vigilance is warranted to prevent and diagnose such iatrogenic injuries.
