Lumbar Disc Herniation Associated with Contralateral Neurological Deficit: Can Venous Congestion Be the Cause?

ABSTRACT

Lumbar disc herniation (LDH) associated with a contralateral neurological deficit is sometimes encountered by surgeons. Compression against the opposite pedicle in case of a large discal herniation and prominent stenotic changes of contralateral side are held responsible for contralateral symptoms and findings. In this study, we report a case of LDH associated with a painless contralateral neurological deficit. Prominent venous engorgement and congestion at the contralateral side of discal herniation were detected during the operation. It's treatment with bipolar coagulation and significant improvement was seen after the operation.
