Abstract
Introduction: Neuromodulation is an important treatment modality for patients with drug-resistant epilepsy who are not candidates for resective or ablative procedures. However, randomized controlled trials and real-world studies reveal that a subset of patients will experience minimal reduction or even an increase in seizure frequency after neuromodulation. We describe our experience with patients who undergo a second intracranial neuromodulation procedure after unsatisfactory initial response to intracranial neuromodulation.
Methods: We performed a retrospective chart review to identify all patients who had undergone deep brain stimulation (DBS) of the anterior nucleus of the thalamus (ANT) or responsive neurostimulation (RNS), followed by additional intracranial neuromodulatory procedures, with at least 12 months of follow-up. Demographic and clinical data, including seizure frequencies, were collected.
Results: All patients had temporal lobe epilepsy. Six patients were treated with concurrent ANT DBS and temporal lobe RNS, and 3 patients transitioned between neuromodulation systems. Of the patients treated concurrently with ANT DBS and temporal lobe RNS, 5 of the 6 patients experienced additional reduction in seizure frequency after adding a second neuromodulation system. Of the patients who switched between neuromodulation modalities, all patients experienced further reduction in seizure frequency.
Conclusions: For patients who do not experience adequate benefit from initial therapy with ANT DBS or temporal lobe RNS, the addition of a neuromodulation system or switching to a different form of neuromodulation may allow for additional reduction in seizure frequency. Larger studies will need to be performed to understand whether the use of multiple systems concurrently leads to improved clinical results in patients who are initially treatment resistant to neuromodulation.
期刊介绍：
''Stereotactic and Functional Neurosurgery'' provides a single source for the reader to keep abreast of developments in the most rapidly advancing subspecialty within neurosurgery. Technological advances in computer-assisted surgery, robotics, imaging and neurophysiology are being applied to clinical problems with ever-increasing rapidity in stereotaxis more than any other field, providing opportunities for new approaches to surgical and radiotherapeutic management of diseases of the brain, spinal cord, and spine. Issues feature advances in the use of deep-brain stimulation, imaging-guided techniques in stereotactic biopsy and craniotomy, stereotactic radiosurgery, and stereotactically implanted and guided radiotherapeutics and biologicals in the treatment of functional and movement disorders, brain tumors, and other diseases of the brain. Background information from basic science laboratories related to such clinical advances provides the reader with an overall perspective of this field. Proceedings and abstracts from many of the key international meetings furnish an overview of this specialty available nowhere else. ''Stereotactic and Functional Neurosurgery'' meets the information needs of both investigators and clinicians in this rapidly advancing field.
