High-Intensity Focused Ultrasound
The Ohio State University Wexner Medical Center is among five sites nationally
to evaluate the safety and effectiveness of a non-invasive MR-guided focused
ultrasound surgery (MRgFUS) technology to perform thalamotomies for intractable
essential tremor. This technology utilizes more than 1,000 ultrasound probes to
deliver a precise lesion under MRI guidance without cutting the skin. The procedure
employs real-time clinical (tremor-reduction and side effect evaluation) and imaging
lesion monitoring (structural MRI and thermography to monitor temperatures) in a
single session, with patients typically experiencing immediate symptom improvement.
Vibhor Krishna, MD; Eric Bourekas, MD, and team are also exploring the application
of this technology for pallidotomy in patients with Parkinson’s disease and seizure-reduction in epilepsy patients.
Robot-assisted surgery has revolutionized surgical therapy for patients with complex
abdominal and pelvic conditions. The application of robots is relatively recent in the
field of neurosurgery. Our team is among the first in the United States to use a robot
for neurosurgical applications, allowing for a very precise implantation of electrodes
in patients undergoing DBS surgery and epilepsy monitoring. This technology
has tremendous application for epilepsy monitoring as well as for targeted drug
and growth factor delivery in patients with neurodegenerative diseases such as
Parkinson’s and Alzheimer’s.
