Robotic long-distance telementoring in neurosurgery.

OBJECTIVE: To test the feasibility of long-distance telementoring in neurosurgery by providing subspecialized expertise in real time to another neurosurgeon performing a surgical procedure in a remote location. METHODS: A robotic telecollaboration system (Socrates; Computer Motion, Inc., Santa Barbara, CA) capable of controlling the movements of a robotic arm, of handling two-way video, and of audio communication as well as transmission of neuronavigational data from the remote operating room was used for the telementoring procedures. Four integrated services digital network lines with a total speed of transmission of 512 kilobytes per second provided telecommunications between a large academic center (Halifax, Nova Scotia) and a community-based center (Saint John, New Brunswick) located 400 km away. RESULTS: Long-distance telementoring was used in three craniotomies for brain tumors, a craniotomy for an arteriovenous malformation, a carotid endarterectomy, and a lumbar laminectomy. There were no surgical complications during the procedures, and all patients had uneventful outcomes. The neurosurgeons in the remote location believed that the input from the mentors was useful in all of the cases and was crucial in the removal of a mesial temporal lobe glioma and resection of an occipital arteriovenous malformation. CONCLUSION: Our initial experience with long-distance robotic-assisted telementoring in six cases indicates that telementoring is feasible, reliable, and safe. Although still in its infancy, telementoring has the potential to improve surgical care, to enhance neurosurgical training, and to have a major impact on the delivery of neurosurgical services throughout the world.

Stabilization clamp for insertion of deep brain stimulation electrodes: technical note.

BACKGROUND: Deep brain stimulation (DBS) electrodes are being implanted with increasing frequency for the management of movement disorders and chronic pain. Success with this neuro-augmentative technique requires accurate electrode lead placement. In order to enhance accuracy of final lead placement and ease of insertion, we describe a useful and reliable DBS electrode lead stabilization device developed and used at our centre. MATERIALS AND METHODS: The DBS electrode stabilization device consists of a 2-clamp system designed to fit the Leksell stereotactic frame. The clamps work in series to secure the stereotactic lead at the time of its final positioning in the desired subcortical target without the need of fluoroscopic control. RESULTS: The DBS electrode stabilization device has been used in 30 patients for 54 electrode implantations at our institution since 2000. Postoperative magnetic resonance imaging was performed in all cases and confirmed accurate placement of the electrodes. CONCLUSIONS: Accurate electrode lead placement is critical for the clinical efficacy of DBS systems. The simple and reliable stabilization device described here is easy to operate and enhances the final placement accuracy of DBS electrode leads.
