Abstract
Background. Vasospasm is a challenging component of the subarachnoid hemorrhage "syndrome" that is unpredictable and very difficult tomonitor using noninvasive or invasivemonitoring technologies in neurocritical units. Methods. We describe the novel use of computerized tomography perfusion (CTP) imaging to choose proper targets for invasive cerebral blood flow monitors. Results. A total of 3 patients are included in this report. CTP parameters were used to generate points of interest to target using invasive cerebral monitoring of the cerebral blood flow and initiate vasodilator therapy and subsequently guide its weaning. Conclusions. CTP can be useful in localizing a specific anatomical target for invasivemonitoring in subarachnoid hemorrhage patients suffering from vasospasm.
