Analysis on surgical outcomes of Cauda Equina Syndrome secondary to Lumbar Disc Herniation

Objective To investigate the characteristics,mechanism,treatment effect of cauda equina syndrome(CES) secondary to lumbar disc herniation(HLD).Methods 38 cases of CES secondary to HLD were reviewed.All the cases were treated with surgery including all laminectomy on 8 cases,center fenestration on 10 caces and bilateral fenestration on 20 cases.According to clinical symptoms and neurologic signs of cauda equina compression,incomplete or complete lesion of the cauda equina was identified and the relationship between surgical time and clinical outcomes were analyzed.Results The 38 patients were followed up for 2-17years,average of 3.4 years.The excellent and good rate in the less than 48-hour group of decompression were73% and in the more than 48hour group were 56%.The cases with complete lesion of CES in these two groups were poor of surgical effect.The surgical effects were related with timeframe of decompression and the degree of damage to the canda equina.Conclusion As a severe neurlogic complications,early diagnosis and operative decompression are advocated in CES.
