Specialty Information

Specialties
  • Diagnostic, Board Certification
Clinical Interests
I am interested in the diagnosis and treatment of cerebrospinal fluid (CSF) leaks, including dural defects and CSF-venous fistulae. Our team specializes in complex dynamic myelography and MRI imaging protocols to localize occult leaks, and treat them using epidural blood patching and fibrin glue.
