Using O-ARM imaging for deep brain stimulation in Parkinson's disease

Evaluation of Intraoperative O-ARM Stereotactic Imaging Versus Conventional Pre-operative Stereotactic Imaging in Deep Brain Stimulation for Parkinson's Disease

Not applicable Interventional University Hospital, Toulouse · NCT05910008

This study is testing whether using O-ARM imaging during deep brain stimulation for Parkinson's disease can make the procedure safer and more comfortable compared to the standard imaging method that requires moving the patient.

What this trial studies

This project aims to compare two techniques for acquiring stereotactic imaging during deep brain stimulation procedures for Parkinson's disease. The study will evaluate the use of O-ARM imaging, which allows for imaging directly in the operating room, against the standard technique that requires patient transfer to a radiology department. By eliminating the need for patient transfer, the O-ARM technique may enhance comfort and safety while expediting the procedure. This is a prospective comparative randomized open-label study, as no previous randomized controlled studies have compared these two imaging methods.

Who should consider this trial

Good fit: Ideal candidates are patients with idiopathic Parkinson's disease experiencing motor fluctuations despite optimal medical treatment and who are approved for deep brain stimulation.

Not a fit: Patients with significant cognitive decline, contraindications to MRI, or severe psychiatric disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved surgical outcomes and patient comfort during deep brain stimulation procedures.

How similar studies have performed: While several teams have begun using O-Arm as a gold standard, this is the first randomized controlled study comparing it with traditional imaging methods.
