Non-targeted thoracic epidural blood patch for spontaneous intracranial hypotension complicated by bilateral subdural haemorrhages in a patient with end-stage renal failure: case based review
摘要
Spontaneous intracranial hypotension (SIH) is a highly disabling neurological syndrome. It occurs secondary to a spinal cerebrospinal fluid leak (CSF) caused by a dural tear, a leaking meningeal diverticulum, or a CSF-venous fistula. SIH is rarely reported in patients with end-stage renal failure (ESRF) on haemodialysis, where fluid shifts may exacerbate CSF pressure dysregulation. We present the case of a female in her twenties referred for a non-targeted epidural blood patch. She had confirmed spontaneous intracranial hypotension, bilateral subdural haemorrhages and a CSF leak of unknown origin on MRI imaging. She had a background of end-stage renal failure and was on intermittent haemodialysis at the time of referral. This is a rare, potentially life-threatening condition with only two previous case reports in the literature in this patient cohort [
