Gliederung

Text

Objective: To assess the feasibility and diagnostic value of intraoperative 3D-fluoroscopy for decompression control in patients with degenerative multilevel cervical stenosis.

Method: The series includes 8 patients with multilevel degenerative cervical stenosis. Prior to surgery, a lumbar drainage was placed for the intraoperative intrathecal administration of contrast agent. All patients were placed in a prone position and carbone Mayfield headholder. After posterior decompression, 10 ml of water-soluble contrast agent (Solutrast® 250) were administered via the lumbar drainage, the operating table tilted until repeated a.-p. or lateral fluoroscopy showed contrast filling of the cervical spinal canal. Thereafter, a 3D-fluoroscopy scan (Medtronic® O-Arm®) was performed and visually evaluated.

Results: All patients tolerated the administration well. The quality of multiplanar images was sufficient to supply information about the presence of residual stenosis. After prior instrumentation, metal artifacts lowered the image quality. In 3 cases, the decompression was continued because residual stenosis was depicted in the 3D rotational images.

Conclusions: Intraoperative myelography followed by 3D-rotational fluoroscopy is a highly useful tool for the control of surgical decompression in multilevel spinal stenosis supplying images comparable to postmyelographic CT. The indication might be expanded to other pathological conditions like tumor or trauma.
