Vasospasm Diagnosis

Diagnosis of vasospasm is made by some combination of clinical, cerebral angiographic, and transcranial doppler ultrasonographic factors.

It can be detected accurately by using MEPs. MEPs are a feasible bedside tool for online VS detection in an intensive care unit and, therefore, may complement existing diagnostic tools 1).

see Angiographic vasospasm.

see Transcranial Doppler for vasospasm diagnosis.


The techniques used for identification of microcirculatory changes are xenon CT scanning, positron emission tomography, single-photon emission computed tomography, MRI perfusion imaging, and CT perfusion (CTP) with CTP being in advantage because of its low cost, rapid imaging, high spatial resolution, and ease of performance 2)

Apart from imaging techniques, the clinical symptoms and the neurological examination of the patient play a crucial role. The disadvantage is that by the time cerebral vasospasm cause clinical symptoms, the ischemic event may have progressed too far, and the chance of a therapeutic intervention may have been missed 3).
