Abstract |
We report a patient who had a bilateral burr-hole drainage due to the development of chronic subdural hematoma after deep
brain stimulation (DBS) for the advanced Parkinson's disease. The patient showed significant improvement during intraoperative
test stimulation with the absence of significant abnormal radiologic findings at the immediate postoperative CT scans. Postoperative course showed progressive deterioration of preoperative akinetic symptoms without notable benefit from therapeutic stimulation. CT scans two months after the surgery showed significant amount of chronic subdural hematoma with the upward displacement of implanted electrodes from the original targets. Bilateral burr-hole drainage was needed because of neurologic deterioration, with a special attention not to disrupt the previously implanted DBS hardware system. Follow-up CT scan revealed resolution of subdural hematoma and return of migrated electrode to its original position. Without DBS lead revision, the patient experienced benefits from the bilateral DBS therapy on follow-up. |
