An innovative interventional radiology treatment has been found to offer chronic migraine sufferers sustained relief of their headaches, according to research being presented at the Society of Interventional Radiology's Annual Scientific Meeting. Clinicians at Albany Medical Center and the State University New York Empire State College in Saratoga Springs used a treatment called image-guided, intranasal sphenopalatine ganglion (SPG) blocks to give patients enough ongoing relief that they required less medication to relieve migraine pain.

During the treatment, which is minimally invasive and does not involve needles touching the patient, researchers inserted a spaghetti-sized catheter through the nasal passages and administered 4 percent lidocaine to the sphenopalatine ganglion, a nerve bundle just behind the nose associated with migraines.

Before treatment, patients reported an average VAS score of 8.25, with scores greater than 4 at least 15 days per month. The day after the SPG block patients' VAS scores were cut in half, to an average of 4.10. Thirty days after the procedure, patients reported an average score of 5.25, a 36 percent decrease from pretreatment. Additionally, 88 percent of patients indicated that they required less or no migraine medication for ongoing relief.
