What Is It?
Lumbar puncture, also known as a spinal tap, is performed to collect a sample of spinal fluid or check the pressure of fluid in the spinal cord. Our radiologists will use X-ray imaging to precisely guide the procedure. Your doctor may have requested this procedure to find a cause for symptoms you have been experiencing.
Lumbar puncture helps to diagnose problems including:
- Bacterial, fungal and viral infections, including meningitis, encephalitis and syphilis
- Bleeding around the brain
- Cancers involving the brain and spinal cord
- Inflammatory conditions of the nervous system, including Guillain-Barre syndrome and multiple sclerosis
How is the Procedure Performed?
During this procedure, a needle is inserted between two vertebrae to remove or measure cerebrospinal fluid—the fluid that surrounds your brain and spine. You will be given a local anesthetic.
How Do I Prep For The Procedure?
Fasting is not required – you may eat and drink normally. You can drive yourself home. You may be asked to hold blood thinning medications.
What Happens After The Procedure?
You will be monitored for 1-2 hours after the procedure. Headache is a potential side effect, but maintaining adequate hydration and avoiding strenuous activities can help alleviate this. The cerebrospinal fluid collected during the lumbar puncture is typically sent for analysis, and results aid in the diagnosis of various neurological conditions.
