Abstract Background: Identification of intracerebral hemorrhage (ICH) patients at risk of hematoma expansion(HE) could facilitate the selection of candidates likely to benefit from therapies aiming to minimize ICH growth. We, therefore, aimed to develop a prediction score for HE that can be quickly used during the critical phase. Methods: A retrospective analysis of clinical features of 317 ICH patients in the Second Affiliated Hospital of Soochow University from January, 2016 to May, 2018 was conducted. Independent risk factors of HE were obtained according to multiple logistic regression, and a prediction score was established and preliminarily evaluated. Results: History of anticoagulants, ultraearly hematoma growth≥2.7ml/h, GCS≤8, and non-enhanced CT signs (island sign, black hole sign, blend sign, niveau formation) exist one or more, were independent risk factors for HE (P <0.05).The C statistics of score was 0.854 (95%CI, 0.803~0.904); P < 0.001); calibration was outstanding (c2=3.323, P = 0.344); decision curve analysis showed the score was safe and reliable, with high net benefit. After dichotomized, the sensitivity, specificity and accuracy of the high-risk group (score≥4.5) were 0.77, 0.85 and 0.83, respectively. Conclusion The score can accurately identify high-risk individuals with HE, swift guide treatment decisions, and can also be used in clinical trials. Keywords: Intracerebral hemorrhage; Hematoma expansion; Non-enhanced CT; Prediction; Score.

Background and Purpose: The characteristics of direct oral anticoagulant (DOAC)-related intracerebral hemorrhage (ICH) have not been fully clarified. We planned to recruit patients prospectively and to investigate the characteristics and outcomes in patients with ICH receiving direct oral anticoagulant (DOAC) and warfarin treatment. Methods: The prospective analysis of stroke patients taking anticoagulants (PASTA) registry study is an observational, multicenter, prospective registry of stroke patients receiving OAC. Patient enrollment started in April 2016 at 25 tertiary centers across Japan. We compared imaging, clinical characteristics, and discharge modified Rankin Scale (mRS) between DOAC- and warfarin-related ICH patients with atrial fibrillation (AF). Results: A total of 154 patients (51 women; median age 77 [quartiles 69-87] years) were analyzed. Of these, 111 patients (72%) received prior DOAC treatment and the remaining 43 (28%) received prior warfarin treatment (Fig. A, B and C). There were no relevant differences in clinical and hematoma characteristics between DOAC- and warfarin-related ICH regarding baseline hematoma volume (median [quartiles]: DOAC, 11 [5-23] mL vs. warfarin, 12 [5-30] mL; P =0.95), rate of hematoma expansion (DOAC, 12/111 [11%] vs. warfarin, 4/43 [9%]; P =0.80), rate of subcortical hemorrhage (DOAC, 15/111 [11%] vs. warfarin, 10/43 [9%]; P =0.80) and the proportion of patients with unfavorable outcome (mRS, 4-6: DOAC 76/108 [70%] vs. warfarin 23/38 [61%]; P =0.26). Cerebral microbleeds (CMBs) were detected more frequently in DOAC group than in warfarin (47/76 [62%] vs. 11/32 [34%]; P <0.01). Subgroup analyses showed that type of DOAC agent did not result in relevant differences in imaging characteristics or outcome (Fig. D and E). Conclusions: Our results showed that there were no significant differences in hematoma characteristics and functional outcome among AF patients with DOAC- or warfarin-related ICH.

Background and Purpose Early hematoma expansion (EHE) has been described in the first 48 hours. SHRINC is a phase 2 prospective safety trial whose primary objective is to assess the safety of pioglitazone (PIO) when administered to patients with spontaneous intracerebral hemorrhage (SICH) compared to standard care. A secondary objective is to characterize the changes in hematoma resolution and expansion over time. This prospective study addresses the natural history, clinical impact, and associated risk factors of late hematoma expansion (LEX) by serial magnetic resonance imaging (MRI) after SICH. Methods SHRINC aims to enroll 78 subjects between the ages of 18-80 with a SICH of ≥ 5 ml. This analysis includes the first 42 patients enrolled. Four subjects were excluded because they did not have an MRI after day 2. A baseline CTH was performed followed by an MRI within 24 hours of symptom onset. Hematoma volume (Hv) was measured on FLAIR sequences using a previously published semi-automated range of interest method. LEX was defined as an increase in Hv > 0.5 ml after the 48 hour MRI. Factors associated with LEX were evaluated with logistic regression. Longitudinal analyses were used for measurements taken over the follow up period. Results: Ten (26.3%) of 38 subjects displayed LEX. Eight subjects had LEX between day 2 to 14, and 4 between days 14 to 28. The median initial Hv was 16.1cc in LEX patients and 24.1cc in those without expansion (NEX) (p=0.23). Lower platelet counts (p=0.04) and BUN levels (p=0.03) were associated with LEX in univariate analysis. Multivariate analysis suggested that those with higher BUN levels were less likely to have LEX (OR=0.81; 95%CI 0.65-0.99). Blood pressure and EHE (13.2%) were not associated with LEX. There was no difference in neurological worsening (NIHSS increase ≥ 4), 6 month mRS or death between LEX and NEX. Conclusion: This is the first prospective study to address LEX with serial MRIs. LEX occurs between day 2 to 14 and day 14 to 28. Elevated BUN levels may decrease the likelihood of LEX. A limitation of our study is that the effect of PIO on LEX could not be evaluated because SHRINC is a blinded trial. Further studies will assess the pathophysiology of LEX and its potential implications in clinical trials evaluating hematoma growth and resolution.

Background: Early neurologic deterioration (END) occurs commonly in intracerebral hemorrhage (ICH) patients being transported by EMS ambulances, but the imaging correlates of END have not been previously delineated. Methods: We analyzed consecutive ICH patients in the Field Administration of Stroke Therapy - Magnesium (FAST-MAG) Trial, a phase 3, multicenter of paramedic-initiated magnesium sulfate vs. placebo for stroke patients presenting within 2 hours of symptom onset. END was defined as a 2-point or greater decrease in the Glasgow Coma Scale (GCS) from paramedic evaluation to ED evaluation. Baseline imaging studies were independently analyzed by 2 neurologists for ICH location, volume, presence of intraventricular hemorrhage (IVH), heterogeneity (defined as >20 point difference in Hounsfield units), irregular hematoma borders, multilobulated appearance, and substantial edema (defined as >0.5cm thickness). Leukoaraiosis was graded using the Fazekas scale for periventricular and deep white matter changes (0-3 for each). Results: Among 127 patients, mean age was 66 (SD 14) years, 34% were women, 35% were Hispanic ethnicity, 83% white, and 84% had a history of HTN. Patients were evaluated by paramedics a median of 23 (IQR 16, 39) minutes after last known well time (LKWT). At that time, the median GCS was 15 (IQR 15-15) and mean SBP/DBP was 177/95 (SD 34/22). Initial post-arrival brain imaging was performed a median of 94 (IQR 77, 117) min after LKWT. Post-arrival study GCS scores were obtained at a median of 108 (IQR 70, 144) min after LWKT. Early neurologic deterioration occurred in 37 (29%) patients. Among these patients, median first ED GCS was 3 (IQR 3-10). On first imaging, compared with neurologically stable patients, END patients had larger hematoma volume (33 cc v 16 cc, p<0.0001), and more frequent presence of intraventricular extension (45% v 20%, p=0.003), midline shift (58% v 22%), substantial edema (54% v 26%, p=0.038), heterogeneous density (50% v 22%, p=0.006), multilobulated appearance (44% v 18%, p=0.002), and irregular border (39% v 14%, p=0.010). Leukoaraiosis and cortical v subcortical location did not affect rates of END. In multivariate analysis, hematoma volume and presence of IVH were imaging findings independently associated with early neurologic deterioration. Conclusions: About 3 in 10 patients with hyperacute ICH neurologically deteriorate during the prehospital and early emergency department course, often before neuroimaging is obtained. Patients with early neurologic deterioration have larger hematoma volume and occurrence of IVH on initial imaging. These findings suggest hematoma expansion prior to ED arrival drives early neurologic deterioration in ICH and emphasize the need for prehospital interventions.
