Bilateral Middle Meningeal Artery Lidocaine Infusion for Chronic Debilitating Migraines

"The study intervention involves the use of 1% cardiac preservative-free lidocaine. Lidocaine is a local anesthetic commonly used in medical procedures to numb a specific area of the body. In this case, the lidocaine is formulated at a concentration of 1% and will be diluted to 50 mL with normal saline.~This treatment is an intra-arterial bilateral lidocaine infusion into the middle meningeal artery (i.e. this is a lidocaine infusion into the brain blood vessels to turn off the pain receptors responsible for causing chronic headaches). Lidocaine is an FDA approved anesthetic (i.e. pain killer) used in common medical practice. Lidocaine, however, has not yet been approved by the FDA for this particular use. For this reason, the use of lidocaine in this study is considered investigational."

All patient who meet eligibility criteria at their baseline visit will be scheduled for the Liocaine procedure.
