Remote XXXX after foramen magnum decompression surgery for Chiari I malformation--case report.

@entity1 @entity1644 @entity390 @entity548 @entity1645 @entity391 @entity450 @entity76
A 47-year-old @entity1 underwent decompressive suboccipital craniectomy and C1 laminectomy with duroplasty in the prone position for @entity1645 and @entity1644 . The arachnoid membrane was not injured. Intraoperative echography showed good enlargement of the subarachnoid space. No closed subcutaneous drain was used. The @entity1 complained of repeated @entity390 and vomiting 3 hours after the operation, and computed tomography revealed @entity548 on postoperative day 1. The @entity548 was treated conservatively, and the symptoms continued only for 3 days after surgery. @entity450 with rapid loss of cerebrospinal fluid (CSF) has occurred in every reported case of @entity548 complicating intracranial and spinal procedures. Loss of CSF is the main pathogenesis of this condition. In our case, the most probable pathomechanism seems to involve stretching of the @entity76 veins due to cerebellar sagging because of dural opening in the prone position and drop in CSF pressure. Such a complication is rare but should be considered after foramen magnum decompression surgery if the @entity1 shows @entity391 .
