Risk of developing seizure after percutaneous endoscopic lumbar discectomy.

Study Design: A retrospective analysis in patients who underwent percutaneous endoscopic lumbar discectomy (PELD) and developed seizures during the procedure; and to identify the risk of developing seizure during PELD by measuring cervical epidural pressure.

Objective: To evaluate clinical significance, characteristics, and risk factors for developing seizure and neck pain in patients undergoing PELD.

Summary And Background Data: Increased epidural pressure during PELD has been reported earlier.

Comparative study of neck pain in relation to increase of cervical epidural pressure during percutaneous endoscopic lumbar discectomy.

Study Design: A prospective study.

Objective: By monitoring cervical epidural pressure (EP) changes throughout the procedure, we intend to discover the effect of percutaneous endoscopic lumbar discectomy (PELD) on cervical epidural pressure and whether there is a correlation between posterior neck pain and increased cervical EP, which is known to have a linear correlation with intracranial pressure (ICP).

Summary Of Background Data: Patients sometimes complain of posterior neck pain during PELD.
