Ischaemic Lesions in Acute Intracerebral Haemorrhage
Sponsor: University of Leicester
Summary
The aim of this observational study is to determine how and why inadequate brain blood flow occurs after bleeding in patients with intracerebral haemorrhage (ICH). Treatment for strokes caused by burst blood vessels involves reducing blood pressure (BP) to stop the bleeding. However, this reduction in BP may affect blood flow, causing blockages in blood vessels within the brain. Fast breathing also affects brain blood flow. Therefore, participants will be asked to undergo a simple brain blood flow assessment using transcranial Doppler (TCD) within 48 hours upon admission to hospital. Patients will then have a follow-up TCD assessment at 4-7 days post-ICH onset, in addition to an MRI scan at \>7 days. This research will help to confirm if blockages after bleeding are caused by reduced blood flow within the brain.

Interventions
Transcranial Doppler ultrasonography (TCD)
TCD will be used to measure cerebral blood velocity (CBv) in the middle and posterior cerebral arteries (MCA and PCA). Following confirmation of a suitable TCD window, participants will undergo a ten-minute rest period in the supine or semi-supine position. Continuous measurements of CBv, blood pressure (BP), heart rate, and end-tidal carbon dioxide will be recorded. Baseline BP will be measured using an automated BP device prior to each recording to allow calibration of the files offline for analysis. This will occur at the first visit and at follow-up, 4-7 days post-onset of intracerebral haemorrhage.
