Statistically significant values are marked in bold.

All given data only refer to the hemisphere ipsilateral to the subdural electrodes. DCI_ACA = delayed infarct volume in the territory of the anterior cerebral artery; DCI_MCA = delayed infarct volume in the territory of the middle cerebral artery; DCI_PCA = delayed infarct volume in the territory of the posterior cerebral artery; DSA = digital subtraction angiography (A1, A2, M1, M2, P1, P2 = first and second segments of ACA, MCA and PCA ipsilateral to the subdural electrodes); ICH = intracerebral haemorrhage; IVH = intraventricular haemorrhage; mbfv_ACA = transcranial Doppler-sonography (TCD)-determined peak mean blood flow velocity of ACA; mbfv_MCA = TCD-determined peak mean blood flow velocity of MCA; mbfv_PCA = TCD-determined peak mean blood flow velocity of PCA; peak_{clusSD-delayed} = peak number of clustered spreading depolarizations (SD) of a recording day during the delayed period between the early post-intervention neuroimage and the late neuroimage after completion of neuromonitoring (clustered SD = SD that occurred less than 1 h apart from the previous SD); peak_{isoSD-delayed} = peak number of isoelectric SDs of a recording day during the delayed period (isoelectric SD = SD in electrically inactive tissue); peak_SD-delayed = peak number of SDs of any type of a recording day during the delayed period; PTDDD_delayed = peak value of a recording day for the total (cumulative) SD-induced depression durations during the delayed period.
