The incidence and correlation of symptomatic epidural hematomas after cervical spine surgery was reviewed and analyzed, then it will provide reference to avoid the occurrence of this complication for the future clinical work.
Full description
43 patients with symptomatic epidural hematoma after cervical spine surgery were enrolled in the Peking University Third hospital from January, 2009 to February, 2017. 86 patients without symptomatic epidural hematoma after cervical spine surgery during the same period were randomly selected as the control group. Demographic information (including gender, age, previous history, smoking history, etc.)，disease parameters (diagnosis, mJOA(modified Japanese Orthopaedics association) score, NDI(neck disability index) score)，laboratory and imaging parameters (including platelet, coagulation function, albumin, and OPLL)，segments，treatment parameters (surgical method, number of surgical segments, operative time, intraoperative blood loss, anesthesia time, whether to use implants) and postoperative conditions (including the time of hematoma occurrence, diagnostic method, emergency debridement operation time, patient improvement before and after debridement) were collected.Firstly, risk factors for symptomatic epidural hematoma after cervical surgery were selected by univariate analysis,then independent risk factors were screened by multiple Logistic regression analysis.
