Intracranial hypotension secondary to a spontaneous cervical nerve root leak repaired using a chimeric rotational paraspinal flap: a multidisciplinary surgical approach. Illustrative case

A multidisciplinary surgical approach utilizing a chimeric rotational paraspinal flap to repair a spontaneous cervical CSF leak at the right C8 nerve root provided robust, vascularized coverage with resolution of SIH signs and symptoms. This flap-based technique offers a durable solution for challenging CSF leaks. https://thejns.org/doi/10.3171/CASE25698.
