abstract = {Spreading depolarizations (SD) contribute to lesion
progression after experimental focal cerebral ischemia while
such correlation has never been shown in stroke patients. In
this prospective, diagnostic study, we investigate the
association of SDs and secondary infarct progression after
malignant hemispheric stroke. SDs were continuously
monitored for 3-9 days with electrocorticography after
decompressive hemicraniectomy for malignant hemispheric
stroke. To ensure valid detection and analysis of SDs, a
threshold based on the electrocorticographic baseline
activity was calculated to identify valid
electrocorticographic recordings. Subsequently SD
characteristics were analyzed in association to infarct
progression based on serial MRI. Overall, 62 patients with a
mean stroke volume of 289.6 ± 68 cm3 were included. Valid
electrocorticographic recordings were found in 44/62
patients with a mean recording duration of 139.6 ± 26.5
hours and 52.5 ± 39.5 SDs per patient. Infarct progression
of more than $5\%$ was found in 21/44 patients. While the
number of SDs was similar between patients with and without
infarct progression, the SD-induced depression duration per
day was significantly longer in patients with infarct
progression (593.8 vs. 314.1 minutes; *p = 0.046).
Therefore, infarct progression is associated with a
prolonged SD-induced depression duration. Real-time analysis
of electrocorticographic recordings may identify secondary
stroke progression and help implementing targeted management
strategies.Keywords: Electrocorticography; malignant
