Transdural Approach to Resection of Intraspinal Extradural Ventral Cysts in the Lumbar spine: A Case Report.

Abstract Background and Importance Intraspinal extradural ventral cysts in the lumbar spine could cause back pain and neurological deficits of the lower extremities. For the resection of this type of space-occupying lesion, transdural approach has not been reported in the literature. Clinical Presentation We presented a 66-year-old man suffered from progressive radiation pain of his bilateral lower extremities. Imaging examination revealed a cystic lesion in ventral side of lumbar spinal canal. We conducted the excision of the cyst with the transdural approach. The symptoms of the patient disappeared immediately after the operation and the recurrence of the symptoms has not been observed in the 3-month follow-up. Conclusion This operation approach is safe and effective. Compared with the previous surgical approach reported in the previous literature, by this approach surgeons could achieve less injury, less operation time, the same surgical outcomes in short term.Therefore,we would like to present this approach to provide a new alternation to deal with the similar lesion.
