Abstract Background Follow-up imaging in intracerebral hemorrhage is not standardized and radiologists rely on different imaging modalities to determine hematoma growth. This study assesses the volumetric accuracy of different imaging modalities (MRI, CT angiography, postcontrast CT) to measure hematoma size. Methods 28 patients with acute spontaneous intracerebral hemorrhage referred to a tertiary stroke center were retrospectively included between 2018 and 2019. Inclusion criteria were (1) spontaneous intracerebral hemorrhage (supra- or infratentorial), (2) noncontrast CT imaging performed on admission, (3) follow-up imaging (CT angiography, postcontrast CT, MRI), and (4) absence of hematoma expansion confirmed by a third cranial image within 6 days. Two independent raters manually measured hematoma volume by drawing a region of interest on axial slices of admission noncontrast CT scans as well as on follow-up imaging (CT angiography, postcontrast CT, MRI) using a semi-automated segmentation tool (Visage image viewer; version 7.1.10). Results were compared using Bland–Altman plots. Results Mean admission hematoma volume was 18.79 ± 19.86 cc. All interrater and intrarater intraclass correlation coefficients were excellent (1; IQR 0.98–1.00). In comparison to hematoma volume on admission noncontrast CT volumetric measurements were most accurate in patients who received postcontrast CT (bias of − 2.47%, SD 4.67: n = 10), while CT angiography often underestimated hemorrhage volumes (bias of 31.91%, SD 45.54; n = 20). In MRI sequences intracerebral hemorrhage volumes were overestimated in T2* (bias of − 64.37%, SD 21.65; n = 10). FLAIR (bias of 6.05%, SD 35.45; n = 13) and DWI (bias of-14.6%, SD 31.93; n = 12) over- and underestimated hemorrhagic volumes. Conclusions Volumetric measurements were most accurate in postcontrast CT while CT angiography and MRI sequences often substantially over- or underestimated hemorrhage volumes.

Intracerebral hemorrhage (ICH) is one of the most devastating forms of cerebrovascular pathology. However, its treatment remains a matter of debate among neurosurgeons and neurologists. The study was to explore the efficacy of minimally invasive surgery (stereotactic catheter drainage, SCD) for patients with severe intracerebral hemorrhage (Glasgow Coma Scale, GCS) score ≤ 8 and hematoma volume ≥ 30 cm3) and to determine predisposing factors for good clinical outcome. A total of 75 patients with severe ICH were included in this retrospective study. Patients were assigned to the SCD group (n=38) or the conventional craniotomy group (n=37). Patients were followed up for 12 months postoperatively, and their clinical parameters were compared. During the operation, the SCD group exhibited a lower bleeding volume ( p<0.001) and shorter operating time ( p<0.001) than the conventional craniotomy group. For postoperative efficacy, the rates of pneumonia and tracheotomy were lower ( p=0.002 and p=0.027, respectively), and the duration of hospital and neurosurgery intensive care unit (NSICU) in days were significantly shorter in the SCD group ( p=0.046 and p=0.047, respectively). Furthermore, patients in the SCD group showed improved modified Rankin Scale (mRS) scores at discharge ( p<0.018) and at 12-month follow up ( p<0.001). Predisposing factors for good clinical outcomes were hematoma volume (<50 cm3, 95% confidence interval (CI): 1.043–1.956, p<0.046), initial GCS score (>6, 95% CI: 3.248–187.466, p<0.001), hypertension (none, 95% CI: 1.440–2.922, p<0.001), and treatment modality (SCD, 95% CI: 1.422–3.226, p<0.001). Taken together, SCD surgery is safe and effective in patients with severe ICH and has fewer complications and better clinical outcomes than conventional craniotomy.

AbstractIntroduction.Several mechanisms in formation of perihemorrhagic edema are activated after contact of brain tissue-extravasated blood in intracerebral hemorrhage. Cysteinyl leukotrienes (cysLT) (C4, D4, E4) are included in this process as significant edema factors and they determine the neurological deficit and outcome. The study aim was a 5-day follow-up (admission/3 day/5 day) of urinary cysLT, hematoma volume, edema volume values and their correlation in patients after spontaneous, primary supratentorial intracerebral hemorrhage.Methods.An enzyme immunoassay was used for urinary cysLT measured in 62 patients and 80 healthy controls. Hematoma and edema volumes were visualized and measured by computed tomography and mathematically calculated with a special spheroid shape formula (V=AxBxC/2).Results.CysLT of hemorrhagic patients (1842.20±1413.2, 1181.54±906.2, 982.30±774.2pg/ml/mg creatinine) were significantly excreted (p<0.01). Brain edema (12.86±13.5, 22.38±21.1, 28.45±29.4cm3) was significantly increased (p<0.01). Hematoma volume values (13.05±14.5, 13.13±14.7, 12.99±14.7cm3) were not significant (p>0.05). A high correlation (multiple regression) between cysLT, hematoma and edema was found on the 3rdday (R=0.6) and a moderate correlation at admission (R=0.3) and on the 5thday (R=0.3).Conclusion.In our 5-day follow-up study a significant cysLT brain synthesis and significant brain edema progression versus constant hematoma volume values in hemorrhagic patients was found. A high correlation between cysLT, hematoma and edema volume was found on the 3rdday, a moderate correlation on admission and on the 5thday, which means that high cysLT and hematoma values were associated with high/moderate edema values.

Abstract Background Neuroinflammation is important in the pathophysiology of spontaneous intracerebral hemorrhage (ICH) and peripheral inflammatory cells play a role in the clinical evolution and outcome. Methodology Blood samples from ICH patients (n = 20) were collected at admission for 5 consecutive days for peripheral blood mononuclear cells (PBMCs). Frozen PBMCs were used for real-time PCR using Taqman probes (NFKB1, SOD1, PPARG, IL10, NFE2L2, and REL) and normalized to GAPDH. Data on hospital length of stay and modified Rankin score (MRS) were collected with 90-day MRS ≤ 3 as favorable outcome. Statistical analysis of clinical characteristics to temporal gene expression from early to delayed timepoints was compared for MRS groups (favorable vs unfavorable) and hematoma volume. Principle findings and results IL10, SOD1, and REL expression were significantly higher at delayed timepoints in PBMCs of ICH patients with favorable outcome. PPARG and REL increased between timepoints in patients with favorable outcome. NFKB1 expression was not sustained, but significantly decreased from higher levels at early onset in patients with unfavorable outcome. IL10 expression showed a negative correlation in patients with high hematoma volume (>30 mL). Conclusions and significance Anti-inflammatory, pro-survival regulators were highly expressed at delayed time points in ICH patients with a favorable outcome, and IL10 expression showed a negative correlation to high hematoma volume.

Background. Although recent studies have focused on the use of metformin in treating ischemic stroke, there is little literature to support whether it can treat intracerebral hemorrhage (ICH). Therefore, this study is aimed at evaluating the possible effects of prestroke metformin (MET) on ICH patients with type 2 diabetes. Methods. From January 2010 to December 2019, all first-ever ICH patients with type 2 diabetes from our hospitals were included. All discharged patients would receive a one-time follow-up at 1 year after admission. Death, disability, and recurrence events were recorded. Results. We included 730 patients for analysis (the median age: 65 [IQR, 56-72] years and 57.7% was men). Of those patients, 281 (38.5%) had received MET before ICH (MET+), whereas 449 (61.5%) had not (MET−). MET (+) patients had a lower median baseline hematoma volume than did MET (-) patients (9.6 ml [IQR, 5.3-22.4 ml] vs. 14.7 ml [IQR, 7.9-28.6 ml]; P < 0.001 ). The inhospital mortality events were not significantly reduced in the MET (+) group compared with the MET (-) group (6.4% vs 8.9%, respectively; absolute difference, −2.5% [95% CI, −3.9% to −0.7%]; OR, 0.70 [95% CI, 0.39 to 1.27]; P = 0.22 ). The 1-year mortality events were not significantly reduced in the MET (+) group compared with the MET (-) group (14.1% vs 17.4%, respectively; absolute difference, −3.3% [95% CI, −5.1% to −1.8%]; OR, 0.73 [95% CI, 0.47 to 1.14]; P = 0.16 ). The 1-year disability events were not significantly reduced in the MET (+) group compared with the MET (-) group (28.4% vs 34.1%, respectively; absolute difference, −5.7% [95% CI, −8.2% to −3.3%]; OR, 0.77 [95% CI, 0.52 to 1.13]; P = 0.18 ). Finally, the recurrence rates in those two groups were not significantly different (MET [+] vs. MET [-]: 6.4% vs. 5.9%; absolute difference, 0.5% [95% CI, 0.2% to 1.3%]; OR, 1.08 [95% CI, 0.51 to 2.28]; P = 0.84 ). Conclusions. Pre-ICH metformin use was not associated with inhospital mortality and 1-year prognosis in diabetic ICH patients.

Object Surgical evacuation of spontaneous intracerebral hemorrhage (sICH) remains a subject of controversy. Minimally invasive techniques for hematoma evacuation have shown a trend toward improved outcomes. The aim of the present study is to describe a minimally invasive alternative for the evacuation of sICH and evaluate its feasibility. Methods The authors reviewed records of all patients who underwent endoscopic evacuation of an sICH at the UCLA Medical Center between March 2002 and March 2011. All patients in whom the described technique was used for evacuation of an sICH were included in this series. In this approach an incision is made at the superior margin of the eyebrow, and a bur hole is made in the supraorbital bone lateral to the frontal sinus. Using stereotactic guidance, the surgeon advanced the endoscopic sheath along the long axis of the hematoma and fixed it in place at two specific depths where suction was then applied until 75%–85% of the preoperatively determined hematoma volume was removed. An endoscope's camera, then introduced through the sheath, was used to assist in hemostasis. Preoperative and postoperative hematoma volumes and reduction in midline shift were calculated and recorded. Admission Glasgow Coma Scale and modified Rankin Scale (mRS) scores were compared with postoperative scores. Results Six patients underwent evacuation of an sICH using the eyebrow/bur hole technique. The mean preoperative hematoma volume was 68.9 ml (range 30.2–153.9 ml), whereas the mean postoperative residual hematoma volume was 11.9 ml (range 5.1–24.1 ml) (p = 0.02). The mean percentage of hematoma evacuated was 79.2% (range 49%–92.7%). The mean reduction in midline shift was 57.8% (p < 0.01). The Glasgow Coma Scale score improved in each patient between admission and discharge examination. In 5 of the 6 patients the mRS score improved from admission exam to last follow-up. None of the patients experienced rebleeding. Conclusions This minimally invasive technique is a feasible alternative to other means of evacuating sICHs. It is intended for anterior basal ganglia hematomas, which usually have an elongated, ovoid shape. The approach allows for an optimal trajectory to the long axis of the hematoma, making it possible to evacuate the vast majority of the clot with only one pass of the endoscopic sheath, theoretically minimizing the amount of damage to normal brain.

Background Factors associated with long-term mortality after spontaneous intracerebral hemorrhage (ICH) have been poorly investigated. Aim Our objective was to identify variables associated with long-term mortality in a prospective cohort of 30-day ICH survivors. Methods We prospectively included consecutive 30-day spontaneous ICH survivors. We evaluated baseline and follow-up clinical characteristics and magnetic resonance imaging (MRI) markers of chronic brain injury as variables associated with long-term mortality using univariate and multivariable Cox proportional hazard regression models. Results Of 560 patients with spontaneous ICH, 304 (54.2%) survived more than 30 days and consented for follow-up. During a median follow-up of 10 years (interquartile range: 8.0–10.5), 176 patients died. The cumulative survival rate at 10 years was 38%. In multivariable analysis, variables independently associated with long-term mortality were age (hazard ratio (HR) per 10-year increase: 1.68, 95% confidence interval (CI): 1.45–1.95), male gender (HR: 1.41, CI: 1.02–1.95), prestroke dependency (HR: 1.66, CI: 1.15–2.39), National Institutes of Health Stroke Scale score (HR per 1-point increase: 1.03, CI: 1.01–1.04), occurrence of any stroke (HR: 2.24, CI: 1.39–3.60), and dementia (HR: 1.51, CI: 1.06–2.16) during follow-up. Among MRI markers, only cerebral atrophy (HR per 1-point increase: 1.50, CI: 1.13–2.00) was independently associated with long-term mortality. Conclusions Preexisting comorbidities, clinical severity at presentation, and significant clinical event during follow-up are associated with long-term mortality. Among MRI markers of chronic brain injury, only cerebral atrophy is associated with long-term mortality.
