Aneurysmal Subarachnoid Hemorrhage, Aneurysm, Ruptured, Arteriovenous Malformations, Intracranial Aneurysm, Intracranial Hemorrhages
Conditions
Brief summary
The study is an observational prospective evaluation of an approved and unchanged clinical management, evaluating different diagnosis methods to assess brain perfusion in patients with an aneurysmal or AVM-related intracranial hemorrhage
Detailed description
The study is a prospective description and evaluation of an approved and unchanged clinical management, evaluating already used different diagnosis methods to assess brain perfusion in patients with atraumatic (aneurysmal, AVM-related, unknown cause) intracranial hemorrhage.
Interventions
This study will use an established local protocol for DCI and intracranial arterial vasospastic stenosis screening, and follow-up to make sure that all patients have the same protocol and don't lose any chance of improvement and good outcome : CT perfusion at different time intervals

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in brain hypoperfusion | Change between day 0, 5, 9 after Intracranial Hemorrhage | Brain hypoperfusion in arterial territories assessed by the delays on perfusion Time to drain (seconds) on CT and/or MR perfusion |
Secondary

|---|---|---|
| Change in brain hypoperfusion 3 | Change between day 0, 5, 9 after Intracranial Hemorrhage | Brain hypoperfusion in arterial territories assessed by the delays on perfusion parameters TMax maps in seconds on CT and/or MR perfusion |
| Change in brain hypoperfusion 4 | Change between day 0, 5, 9 after Intracranial Hemorrhage | Brain hypoperfusion in arterial territories assessed by the delays on perfusion parameters Mean transit time on CT and/or MR perfusion in seconds |
| Change in vessel size | Change between day 0, 5, 9 after Intracranial Hemorrhage | Change in the vessel size measured on digital subtraction angiography (DSA) and computed tomography angiogram (CTA) in millimeters |
| Time to next endovascular intervention for vasospastic stenosis | Number of days after the endovascular procedure until the next procedure in days, up to 4 weeks | Delay between two procedures for the same indication |
| Transcranial Doppler | Change between day 0, 5, 9 after Intracranial Hemorrhage | Reduction in intracranial vasospasm assessed by the targeted vessel velocity in meters per second |
| modified Rankin Scale at 3 months | 3 months after Intracranial Hemorrhage | clinical evolution (mRS between 0 and 6, a higher score means a worse outcome) |
| Change in Glasgow coma scale | Change between day 0, 5, 9 after Intracranial Hemorrhage | Glasgow coma scale (GCS between 3 and 15, a higher score means a better outcome) |
| Change in National Institutes of Health Stroke Scale score | Change between day 0, 5, 9 after Intracranial Hemorrhage | National Institutes of Health Stroke Scale (NIHSS between 0 and 42, a higher score means a worse outcome) |
| Change in the monitoring of tissue oxygen pressure (PtiO2) | Change between day 0, 5, 9 after Intracranial Hemorrhage | Monitoring of tissue oxygen pressure (PtiO2) |
| Change in the number of new ischemic lesions | Change between day 0, 5, 9, 21 after Intracranial Hemorrhage | Number of new ischemic lesions on non-contrast CT scan |
| Brain Hypoperfusion 2 | Change between day 0, 5, 9 after Intracranial Hemorrhage | Reduction in brain hypoperfusion assessed by the volumes on different perfusion parameters time to peak (in seconds) on CT and/or MR perfusion |
