Background and Purpose-Various grading scores to predict survival after intracerebral hemorrhage (ICH) have been described. We aimed to test the accuracy and clinical usefulness of 3 well-known scores (original ICH score, modified ICH score, and ICH grading scale) in a large unselected cohort of typical ICH patients. Methods-A total of 1364 ICH cases were referred to our center from January 1, 2008, to October 17, 2010 were prospectively recorded, and the first computed tomography brain scan was retrospectively reviewed to determine ICH volume and location and to identify intraventricular hemorrhage. The original ICH, ICH grading scale, and modified ICH score were calculated. Receiver operating characteristic and decision curves for 30-day mortality were generated. Results-A total of 1175 patients were included in the final analysis. All 3 scores and the Glasgow Coma Scale (GCS) divided cases into groups with highly significant differences in mortality. The area under the receiver operating characteristic curve was very similar for original ICH (0.861), ICH grading scale (0.874), and GCS (0.872), but was less for modified ICH score (0.824). Age was much less predictive (0.565). Combining GCS with age, log ICH volume, and intraventricular hemorrhage to derive a multifactorial risk of death at 30 days significantly increased the area under the receiver operating characteristic curve (0.897). All scores and GCS demonstrated a similar net benefit for threshold probabilities of 10% to 95%. Above 95%, the net benefit of GCS became inferior to the prognostic scores. Conclusions-Although existing grading scores are highly predictive of 30-day mortality, GCS alone was as predictive in our cohort, but age was not.

BACKGROUND AND PURPOSE Studies in animal models suggest that inflammation is a major contributor to secondary injury after intracerebral hemorrhage (ICH). Direct, noninvasive monitoring of inflammation in the human brain after ICH will facilitate early‐phase development of anti‐inflammatory treatments. We sought to investigate the feasibility of multimodality brain imaging in subacute ICH. METHODS Acute ICH patients were recruited to undergo multiparametric MRI (including dynamic contrast‐enhanced measurement of blood‐brain barrier transfer constant (Ktrans) and PET with [11C]‐(R)‐PK11195). [11C]‐(R)‐PK11195 binds to the translocator protein 18 kDa (TSPO), which is rapidly upregulated in activated microglia. Circulating inflammatory markers were measured at the time of PET. RESULTS Five patients were recruited to this feasibility study with imaging between 5 and 16 days after onset. Etiologies included hypertension‐related small vessel disease, cerebral amyloid angiopathy (CAA), cavernoma, and arteriovenous malformation (AVM). [11C]‐(R)‐PK11195 binding was low in all hematomas and 2 (patient 2 [probable CAA] and 4 [AVM]) cases showed widespread increase in binding in the perihematomal region versus contralateral. All had increased Ktrans in the perihematomal region (mean difference = 2.2 × 10−3 minute−1; SD = 1.6 × 10−3 minute−1) versus contralateral. Two cases (patients 1 [cavernoma] and 4 [AVM]) had delayed surgery (3 and 12 months post‐onset, respectively) with biopsies showing intense microglial activation in perilesional tissue. CONCLUSIONS Our study demonstrates for the first time the feasibility of performing complex multimodality brain imaging for noninvasive monitoring of neuroinflammation for this severe stroke subtype.

ObjectivesTo identify factors associated with the decision to transfer and/or operate on patients with intracerebral haemorrhage (ICH) at a UK regional neurosurgical centre and test whether these decisions were associated with patient survival.DesignRetrospective cohort study.Setting14 acute and specialist hospitals served by the neurosurgical unit at Salford Royal NHS Foundation Trust, Salford, UK.ParticipantsAll patients referred acutely to neurosurgery from January 2008 to October 2010.Outcome measuresPrimary outcome was survival and secondary outcomes were transfer to the neurosurgical centre and acute neurosurgery.ResultsWe obtained clinical data from 1364 consecutive spontaneous patients with ICH and 1175 cases were included in the final analysis. 140 (12%) patients were transferred and 75 (6%) had surgery. In a multifactorial analysis, the decision to transfer was more likely with younger age, women, brainstem and cerebellar location and larger haematomas. Risk of death in the following year was higher with advancing age, lower Glasgow Coma Scale, larger haematomas, brainstem ICH and intraventricular haemorrhage. The transferred patients had a lower risk of death relative to those remaining at the referring centre whether they had surgery (HR 0.46, 95% CI 0.32 to 0.67) or not (HR 0.41, 95% CI 0.22 to 0.73). Acute management decisions were included in the regression model for the 227 patients under either stroke medicine or neurosurgery at the neurosurgical centre and early do-not-resuscitate orders accounted for much of the observed difference, independently associated with an increased risk of death (HR 4.8, 95% CI 2.7 to 8.6).ConclusionsThe clear association between transfer to a specialist centre and survival, independent of established prognostic factors, suggests aggressive supportive care at a specialist centre may improve survival in ICH and warrants further investigation in prospective studies.
