Popis: Migraine is one of the main causes of disability in modern world. Treatment of chronic refractory migraine (RCM) would be a challenge even for experienced physician. The aim of this study was to analyze the effect of combination therapy for RCM: greater occipital nerve’s (GON) pulsed radiofrequency (PRF) and botulinum toxin injections. We observed 6 female patients, suffering from RCM according to the European Headache Federation criteria. All patients had long history of migraine (5–44 years) with conservative treatment failure (at least three medication groups). Their migraine could be classified as refractory for long period of time (1–10 years). All of our patients passed a combination of PRF and BTA injection as consecutive 1-day treatments. Botulinum toxin type A injections were done in accordance to the PREEMPT protocol, followed by ultrasound-guided PRF of GONs bilateral. The observation period was 6 months after the procedure. We observed a positive response to treatment in all patients with dramatic reduction of pain intensity (from 7 ± 1 to 2 ± 2 on NRS scale) and significant decrease in the number of headache days (from 22 ± 5 to 4 ± 4) during first month after treatment. Two patients (30%) were pain free after the treatment until the end of the observation. No adverse effects were registered. Bilateral GON’s PRF followed by botulinum toxin therapy as 1-day treatment may be a useful option for the treatment of refractory chronic migraine. These interventional procedures are effective, minimally invasive, inexpensive, safe, and well-tolerated and can be performed on an outpatient basis.
