Delayed Cerebral Infarction Beyond Endoluminal Spasmolysis and Induced Hypertension

This study examines what happens when the standard treatments for brain artery spasms after a brain bleed (subarachnoid haemorrhage) fail — specifically, how often patients still develop brain infarctions (areas of brain tissue damage) and what factors predict this outcome. **You may be eligible if...** - You are 18 years or older - You are receiving critical care after a subarachnoid haemorrhage (bleeding around the brain) - The source of the bleed (a brain aneurysm) has been treated (either by surgery or a minimally invasive procedure) - You are experiencing suspected or confirmed severe cerebral vasospasm (dangerous narrowing of brain arteries) **You may NOT be eligible if...** - Your expected survival is less than five days - Your Transcranial Doppler ultrasound signal is too weak to measure - You are pregnant Talk to your doctor to see if this trial is right for you.
