Long term delay in onset of prevertebral hematoma following anterior cervical discectomy and fusion: A case report

摘要

Post-operative hematoma following anterior cervical discectomy and fusion (ACDF) is an uncommon but feared complication. Typically, these complications present in the immediate post-operative period. We present a case of a 51 year-old woman who underwent a C4-5 ACDF for left sided radicular pain. Her immediate post-operative course was uncomplicated, but she presented 6 weeks subsequently to the emergency department with neck swelling, difficulty swallowing, cough, and shortness of breath. She was found to have a 4.5 cm anterior neck hematoma with settling of the instrumentation and a new C4 vertebral fragment protruding anteriorly. She underwent evacuation of hematoma without clear evidence of a bleeding source. After several days of observation, she was discharged home and ultimately had resolution of her presenting symptoms. Most hematomas resulting in airway compromise appear in the immediate post-operative period, but a high index of suspicion must remain high in any patient with a prior anterior cervical surgery presenting with symptoms of pre-vertebral compression or respiratory compromise.
