Prediction of Poor Outcome in Cerebellar Infarction by Diffusion MRI.
Identification of patients with posterior fossa infarction at risk for neurological deterioration remains a challenge. MRI-based assessments of MCA infarction can predict poor outcome. Similar quantitative imaging measures after cerebellar stroke have not been studied. We tested the hypothesis that MRI-based volumetric assessment of cerebellar infarcts can provide reliable information for the prediction of poor outcome. ⋯ Quantitative volumetric measurement predicts poor outcome of cerebellar stroke patients, even when controlling for age and NIHSS. Quantitative analysis of diffusion MRI may assist in identification of patients with cerebellar stroke at highest risk of neurological deterioration. Prospective validation is warranted.

Although intracerebral hemorrhage (ICH) is a common form of cerebrovascular disease, little is known about factors leading to neurological deterioration occurring beyond 48 h after hematoma formation. The purpose of this study was to characterize the incidence, consequences, and associative factors of late neurological deterioration (LND) in patients with spontaneous ICH. ⋯ LND is a common phenomenon in patients with ICH; further, LND appears to affect outcome. Independent predictors of LND include hematoma volume, intraventricular hemorrhage, and blood glucose on admission. Progression of perihematomal edema may be one mechanism for LND.

Recovery is common after subarachnoid hemorrhage (SAH), even in patients who are severely disabled at hospital discharge. Little is known about predictors of late recovery in such patients, even though such knowledge may influence treatment decisions. We hypothesized that cerebral infarction volume would be associated with 3 months outcomes in patients who are severely disabled at 14 days. ⋯ After SAH, even with severe neurological injury at 14 days, good recovery is frequent and is associated with lower infarction volume. These data may help clinicians inform surrogate decision makers as they plan the future care of such severely disabled patients.

Early Major Worsening in Ischemic Stroke: Predictors and Outcome.
We aimed to investigate the characteristics and outcome of patients suffering early major worsening (EMW) after acute ischemic stroke (AIS) and assess the parameters associated with it. ⋯ Worsening of ≥8 points in the NIHSS score during the first 24 h in AIS patients is related to cervical artery dissection and hemorrhagic transformation. It justifies urgent repeat parenchymal and arterial imaging. Both conditions may be influenced by targeted interventions in the acute phase of stroke.

Readmission within 30 days is increasingly evaluated as a measure of quality of care. There are few data on the rates of readmission after subarachnoid hemorrhage (SAH). ⋯ Demographics, severity of neurologic injury, radiographic cerebral infarction, and outcomes were not associated with readmission after SAH. Markers of a more complicated hospital course (ICU and hospital LOS, EVD placement) were associated with 30-day readmission. Most readmissions were for infections acquired after discharge. Readmission within 30 days is difficult to predict, and, since the most common reason was infection acquired after discharge, it may be difficult to prevent without an integrated health system and coordinated care.
