Outcome Measures

Primary Outcomes (1)

  • Delayed Cerebral Ischemia - Clean groups

    Delayed Cerebral Ischemia as defined by Vergouwen et al in Stroke 2010;41(10):2391-2395. We found confirmation/exclusion of DCI difficult in a few patients. To minimize error, two clinicians reviewed all clinical, biochemical and radiological data, obtained 3 weeks from ictus, and independently assessed if any clinical deterioration fulfilled the criteria of delayed cerebral ischemia. Furthermore, included patients were categorized as "definitely DCI", "probably DCI", "probably not DCI" or "definitely not DCI". Therefore we decided to modify our primary outcome measure in this case-control study to compare "definitely DCI" vs. "definitely not DCI".

    21 days

Secondary Outcomes (5)

  • Early brain injury: Comparison of microRNA profiles with clinical neurology following occlusion of the aneurysm

    Assessed at the first wake-up call following clip or coil

  • Association of microRNA-profile with 3 month outcome

    Follow up examination at 3 month or as close to this

  • Delayed Cerebral Ischemia as defined by Vergouwen et al in Stroke 2010;41(10):2391-2395. Large groups.

    21 days following ictus

  • Relation of microRNA profile to cerebral infarction as defined by Vergouwen et al in Stroke 2010;41(10):2391-2395.

    Following a blinded description of CT-scans

  • Relation of microRNA profile to the regional area of cerebral injury

    Following a blinded description of CT-scans

Study Arms (3)

SAH with DCI

After 21 days from ictus the patients with subarachnoid hemorrhage are stratified to group 1 or 2 depending on their development of delayed cerebral ischemia.

SAH without DCI

After 21 days from ictus the patients with subarachnoid hemorrhage are stratified to group 1 or 2 depending on their development of delayed cerebral ischemia.

Neurological healthy controls

12 patients (ASA 1) undergoing spinal anesthesia for orthopedic surgery have 2 ml of cerebrospinal fluid drawn preceding injection of local analgetic.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Group 1+2: Patients admitted to Neurointensive Department in Rigshospitalet. Group 3: Patients undergoing spinal anesthesia for orthopedic surgery in Bispebjerg Hospital.

You may qualify if:

  • Patient admitted to the neurointensive care unit with aneurismal subarachnoid hemorrhage
  • External ventricular drainage with 5 days of ictus
  • Age \> 18 years

You may not qualify if:

  • Glasgow Coma Score (GCS) continuously \< 7 during the first 5 days following ictus
  • A known and proven complication (rebleeding, clip/coil complication, cardiopulmonal complication requiring full sedation, ventriculitis e.g.) leads to a GCS \< 7 thereby preventing the detection of DCI.
