Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The causal correlation between presence of cerebral vasospasm measured daily by transcranial Doppler sonography (TCD) and occurrence of cerebral ischemia detected by cranial computed tomography scan (CCT) is not finally verified.
First studies demonstrated that ultrasound perfusion imaging (UPI) allows the detection of perfusion deficits in middle cerebral artery infarction.
The purpose of our study is to evaluate the diagnostic and prognostic value of UPI to predict delayed cerebral ischemia. In our trial we compare parameters of UPI (b= rise rate, A= plateau of acoustic intensity) in patients with aneurysmal subarachnoid hemorrhage with results of follow-up cranial computed tomography scans (CCT), TCD results and clinical outcome.
