Cervicogenic headache has been known to originate from the convergence of the upper 3 cervical and trigeminal afferents. The administration of conservative treatments, interventional procedures, and more recently, pulsed radiofrequency, has been used to relieve cervicogenic headache. In this study, the authors evaluated the clinical efficacy and safety of pulsed radiofrequency targeting the mid-cervical medial branches. ⋯ In patients with intractable cervicogenic headache, pulsed radiofrequency treatment targeting the mid-cervical medial branches resulted in a satisfactory, long-lasting outcome without serious complications.
