Objective. The influence of cognitive impairment after mild traumatic brain injury (mTBI) on cerebral vascular perfusion has been widely concerned, yet the resting-state cerebral blood flow (CBF) connectivity alterations based on arterial spin labeling (ASL) in mild traumatic brain injury (mTBI) remain unclear. This study investigated region CBF and CBF connectivity features in acute mTBI patients, as well as the associations between CBF changes and cognitive impairment. Materials and Methods. Forty-five acute mTBI patients and 42 health controls underwent pseudocontinuous arterial spin labeling (pCASL) perfusion magnetic resonance imaging (MRI). The alterations in regional CBF and relationship between the CBF changes and cognitive impairment were detected. The ASL-CBF connectivity of the brain regions with regional CBF significant differences was also compared between two groups. Neuropsychological tests covered seven cognitive domains. Associations between the CBF changes and cognitive impairment were further investigated. Results. Compared with the healthy controls, the acute mTBI patients exhibited increased CBF in the bilateral inferior temporal gyrus (ITG) and decreased CBF in the right middle frontal gyrus (MFG), the bilateral superior frontal gyrus (SFG), and the right cerebellum posterior lobe (CPL). In the mTBI patients, significant correlations were identified between the CBF changes and cognitive impairment. Importantly, the acute mTBI patients exhibited CBF disconnections between the right CPL and right fusiform gyrus (FG) as well as bilateral ITG, between the left SFG and left middle occipital gyrus (MOG), and between the right SFG and right FG as well as right parahippocampal gyrus. Conclusion. Our results suggest that acute mTBI patients exhibit both regional CBF abnormalities and CBF connectivity deficits, which may underlie the cognitive impairment of the acute mTBI patients.

Introduction: The radiological and clinical follow-up of patients with a mild traumatic brain injury (mTBI) and an intracranial hemorrhage (ICH) is often heterogeneous, as there is no official guideline for CT scan control. Furthermore, public sector health expenditure has increased significantly as the number of MRI and CT scan almost doubled in Canada in the last decade. Therefore, the main objective of this study was to describe the current management practices of mTBI patients with intracranial hemorrhage at two level-1 trauma centers. Methods: Design: An historical cohort was created at the CHU de Québec – Hôpital de l'Enfant-Jésus (Québec City) and Hôpital du Sacré-Coeur (Montréal). Consecutive medical records were reviewed from the end of 2017 backwards until sample saturation using a standardized checklist. Participants: mTBI patients aged ⩾16 with an ICH were included. Measures: The main and secondary outcomes were the presence of a control CT scan and neurosurgical consultation/admission. Analyses: Univariate descriptive analyses were performed. Inter-observer measures were calculated. Results: Two hundred seventy-four patients were included, of which 51.1% (n = 140) came from a transfer. Mean age was 60.8 and 68.9% (n = 188) were men. Repeat CT scan was performed in 73.6% (n = 201) of our patients as 12.5% showed a clinical deterioration. The following factors might have influenced clinician decision to proceed to a repeat scan: anticoagulation (association of 87.1% with scanning; n = 27), antiplatelet (84.1%; 58), GCS of 13 (94.1%; 16), GCS of 14 (75%; 72) and GCS of 15 (70.2%; 111). 93.0% (n = 254) of patients had a neurosurgical consultation and only 6.7% (17) underwent a neurosurgical intervention. Conclusion: The management of mild traumatic brain injury with hemorrhage uses a lot of resources that might be disproportionate with regards to risks. Further research to identify predictive factors of deterioration is needed.
