Lumbar Puncture


Lumbar Puncture is the insertion of a needle between two bones (vertebrae) of the lower spine to obtain a sample of cerebrospinal fluid (CSF). Fluoroscopic and Computed Tomography (CT) Imaging may be required for accurate needle placement; on some occasions a combination of imaging may be required.

A specialist known as an Interventional Radiologist often performs these procedures.  The procedure is sometimes called a spinal tap.

Why do I need this procedure?

Your Doctor has asked for this test to be performed because you may experience some or all of the following;

  • Fever
  • Severe persistent headaches or neck stiffness
  • Loss of balance, clumsiness or lack of coordination
  • Ongoing confusion
  • Numbness, tingling or weakness in arms and/or legs
  • Headaches of Unknown Cause – after other avenues have been explored
  • Check for the presence of blood in the CSF
  • Measure the pressure of the CSF in the space surrounding the spinal cord

What should I expect?

  • The procedure can take between 20 – 60mins.
  • You may be required to take some time off work – please let the nurses know so they can organise a medical certificate for you. An attendance certificate can be provided for your carer on the day of your procedure.
  • Please make sure you have someone to pick you up after your procedure. You procedure will be cancelled if you don’t have an escort.  Please contact MIVIR as soon as possible if this cannot be arranged.
