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 It Treated?
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?
No preparation is required. No aspirin or blood thinners to be taken 5 days prior to the procedure.
What Happens 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.
Patients often receive post-procedure instructions to monitor for any signs of complications, such as infection or unusual symptoms, and may be advised to contact their healthcare provider if concerns arise.
Overall, recovery from a diagnostic lumbar puncture is usually swift, and individuals can often resume their normal activities shortly after the procedure.
