Abstract:Objective To investigate the causes,clinical treatment and preventive measures of early epidural hematoma after anterior cervical canal decompression. Methods We retrospectively analyzed the clinical data of 1 685 patients admitted to the Second Affiliated Hospital of Hainan Medical College from January 2010 to December 2021 who underwent concurrent anterior cervical decompression surgery.All patients were treated with anterior cervical subtotal corpectomy and decompression and fusion or anterior cervical discectomy and decompression and fusion,among which 5 cases were complicated with early epidural hematoma.2 cases were male and 3 cases were female.The patients aged 55~69 years,with an average age of (62.40±5.27) years.Two cases were diagnosed with ossification of posterior longitudinal ligament of cervical vertebra and spinal cord before operation.The causes,appearance time,main clinical manifestations and reoperation time of early epidural hematoma in 5 patients were analyzed.Results All 5 patients were followed up for an average of (17.20±4.32) months.All 5 patients with early epidural hematoma occurred within 6 hours after surgery and underwent emergency surgical treatment.Cervical magnetic resonance examination before surgery showed that the hematoma compressed the spinal cord,and the operation proved to be the formation of epidural hematoma.All 5 patients recovered to the preoperative level or better than the preoperative level.Conclusion The peak period of early epidural hematoma occurrence after anterior cervical decompression surgery is within 6 hours after surgery.The main clinical manifestation of early epidural hematoma is progressive neurological impairment,and the diagnosis is mainly based on clinical manifestations and cervical magnetic resonance examination.Emergency operation to remove hematoma after diagnosis is the main measure to avoid permanent damage to neurological function.
