Migraine Relief

SphenoCath -- or, Sphenopalatine Ganglion Block (SPGB)

Instant and lasting relief from migraines. 

Migraines, chronic headaches, facial pain, and trigeminal neuralgia can all cause crippling pain. Traditionally, there have been very little effective chronic headache treatments. Two out of three patients discontinue prescription medications due to inadequate relief and significant side-effects.

This breakthrough headache treatment is a simple therapy that is completed in just minutes. The majority of patients experience immediate relief that lasts for months. SphenoCath is a soft, tiny applicator used for a sphenopalatine ganglion (SPB) nerve block. Interventional radiologists use image guidance to apply medication to the SPG, a bundle of nerves in the back of the nasal cavity. Once applied, the SPG block can relieve headache pain instantly and prevent future migraines.

How to Schedule a SphenoCath

To schedule a consultation with our Interventional Radiologists, call Phelps Memorial at 308.995.3305.

What to Expect

The SPGB procedure is done in our Imaging Department at Phelps Memorial. The nasal passages are numbed with a spray. Then, a small, flexible catheter is inserted into your nostrils (one side at a time) while lying flat on the back with the head tipped back. Special x-ray equipment is used to see that the catheter is in the right position to make sure the medication is placed in the ganglion area. Placement is verified by using a small amount of x-ray contrast with the catheter, followed by a small amount of lidocaine. The lidocaine is absorbed through the nasal passage tissues to "reset" the ganglion.

How to Prepare

  • Remove earrings, necklaces and other jewelry above the shoulders.
  • Avoid ponytails and hair accessories on the back of the head to avoid discomfort while laying on the back.
  • Continue to take regular medications, including migraine medications.
  • Eat a regular diet.
  • Continue normal caffeine intake.
  • Most patients will be able to resume normal activities within 15-20 minutes following the procedure.

How Effective is SPGB

If you are experiencing a migraine during the procedure, there may be immediate relief. If you do not have a migraine at the time, but normally experience them at regular intervals (2-3 times per week, with changes in weather, menstrual period, etc.) you may notice that you get through these times without suffering from a migraine.

Lasting Effects

The SPGB procedure has been found to be effective from a couple of weeks to over a year. It has also been shown to have a cumulative effect, where you may get longer relief each time you have the procedure done, up to a certain point. On average, patients may need to have the procedures repeated 3-4 times per year.
