- "Large territorial infarct" refers to infarcts detected during the endovascular coiling procedure or immediately post-procedure (i.e., CT performed for suspicion of cerebral infarct or other complication). This does not imply having to wait 24-48 hours post-procedure to perform the protocol-mandated CT scan in order to randomize a patient. Evaluation for a new major neurological deficit post-procedure implies reversal of sedation and performance of a GCS examination (verbal scores in intubated patients may be extrapolated from the eye-opening and motor scores using predefined values). If a new major neurological deficit does not improve within 12 hours after the coiling procedure, the patient cannot be included.
