4.2. Can Radiological Vasospasm Be Correlated to DCI Incidence?
confusion, vasospasm, hemorrhage, headache, DCI
PCT, VASOSPASM, COMPLICATION, HEMORRHAGE, DCI
The lower percentage of DCI in our study can be explained by the fact that only the radiological definition of DCI was used in this study and that the early screening of vasospasm may have decreased the percentage of this complication (23% in our study). In the literature, the incidence of DCI is between 50 and 70%. Westermaier et al. [It is also important to note that, in our study, 26.7% of patients with grade 1 and grade 2 WFNS had vasospasm based on PCT. This rate is only slightly lower than other (higher) grades. This justifies the equivalent careful monitoring of these patients, although it is not clear whether PCT findings fully correlate with angiographic and/or clinical vasospasm. In addition, one must take into account the difficulty in the detection of relevant clinical symptoms in patients presenting with complex neurological conditions due to a mixture of symptoms not exclusively associated with hemorrhage, such as headache, confusion, sedation and so forth. The distinction between clinical vasospasm and symptomatic radiological vasospasm [
