We report a case of heparin-induced thrombocytopenia (HIT) that was complicated by acute intracerebral hemorrhage (ICH) and bilateral adrenal hemorrhage. In the setting of worsening thrombocytopenia, the risk of expansion of ICH and additional thrombotic events is concerning; hence, we employed plasmapheresis to reduce thrombotic risk. ⋯ This case helps illustrate the utility of plasmapheresis in management of HIT when anticoagulation is contraindicated.

Large hemispheric infarction (LHI), also known as malignant middle cerebral infarction, is a devastating disease associated with significant disability and mortality. Clinicians and family members are often faced with a paucity of high quality clinical data as they attempt to determine the most appropriate course of treatment for patients with LHI, and current stroke guidelines do not provide a detailed approach regarding the day-to-day management of these complicated patients. ⋯ The panel devised a series of clinical questions related to LHI, and assessed the quality of data related to these questions using the Grading of Recommendation Assessment, Development and Evaluation guideline system. They then developed recommendations (denoted as strong or weak) based on the quality of the evidence, as well as the balance of benefits and harms of the studied interventions, the values and preferences of patients, and resource considerations.

In subarachnoid hemorrhage (SAH), brain injury visible within 48 h of onset may impact on admission neurological disability and 3-month functional outcome. With volumetric MRI, we measured the volume of brain injury visible after SAH, and assessed the association with admission clinical grade and 3-month functional outcome. ⋯ The volume of brain injury visible on DWI and FLAIR within 48 h after SAH is proportional to neurological impairment on admission. Moreover, FLAIR-imaging implicates chronic brain injury-predating SAH-as potentially relevant cause of poor functional outcome.

This study assessed whether early levels of biomarkers measured in CSF within 24-h of severe TBI would improve the clinical prediction of 6-months mortality. ⋯ These data suggest that early levels of MAP-2 in combination with clinical data provide enhanced prognostic capabilities for mortality at 6 months.

Perihematomal edema exacerbates the mass effect of hematoma and contributes to early neurological deterioration after intracerebral hemorrhage (ICH). Oxygen therapy has protective effects on the blood-brain barrier (BBB). We aimed to examine the effects of oxygen therapy on edema formation and BBB permeability after ICH. ⋯ Very early oxygen therapy can attenuate edema formation and BBB disruption after ICH, but the brief therapeutic time window suggests that the translational potential is limited.
