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.

Introduction: In patients with intracerebral hemorrhage (ICH) perihemorrhagic edema (PHE) seems to play a predictive role besides initial hematoma size, clinical status and intraventricular bleeding (IVH). PHE may exceed the initial hematoma volume by up to 600% thereby leading to increased intracranial pressure (ICP) which may cause severe clinical deterioration. EUSI and ASA guidelines recommend the use of intravenous mannitol or hypertonic saline (HS) in order to reduce elevated ICP. However, clinical data suggest that HS may be superior to mannitol in lowering ICP and clinical data concerning the effect of mannitol on PHE as a cause of elevated ICP is limited. We aimed to investigate the effect of mannitol on PHE after ICH. Methods: Patients with supratentorial spontaneous ICH treated with 20% intravenous mannitol solution (125-250ml every 6h) for 5-10 days and controls matched for ICH volume, age and IVH who did not receive any osmotic agents during the course of treatment were identified retrospectively from our institutional ICH database. PHE volume was calculated on diagnostic CT scans performed on days 1, 2-3, 4-6, 7-9 and 10-12 using a validated volumetric algorithm. Frequency of elevated ICP up to day 12 (ICP burden), modified Rankin Scale (mRS) after rehabilitation (approx. day 90) and PHE evolution were assessed as outcome variables. Results: 44 ICH patients treated with mannitol and 43 controls were included. Basic characteristics did not differ between groups (median ICH volume day 1: 32.9 mL (IQR 16.3 - 54.0) and 27.7 mL (IQR 22.4 - 37.1), p=0.786; median age 71 y (IQR 61.5 - 77) and 72 y (IQR 66 - 81), p=0.269; median PHE volume day 1: 24.3 mL (IQR 16.0 - 38.8) and 24.3 mL (IQR 17.1 - 32.1), p=0.592, respectively). In the mannitol group PHE volume exceeded to a greater extent than in controls (PHE on day 10-12: 60.1 mL (SD 33.6) vs. 36.8 mL (SD 23.2), p=0.005). Median ICP burden was higher in the mannitol group (0 (IQR 0 - 7.75) vs. 0 (IQR 0), p=0.016). Median mRS did not differ between both groups (4 (IQR 4-6) vs. 4 (IQR 3-6), p=0.321). Conclusions: We found no effect of mannitol use on the general evolution of PHE and ICP. Other underlying mechanisms may explain the short-term effect of mannitol bolus administration on ICP in patients with spontaneous supratentorial ICH.

Perihemorrhagic Edema

ObjectiveTo determine the influence of intracerebral hemorrhage (ICH) location and volume and hematoma surface on perihemorrhagic edema evolution.MethodsPatients with ICH of the prospective Universitätsklinikum Erlangen Cohort of Patients With Spontaneous Intracerebral Hemorrhage (UKER-ICH) cohort study (NCT03183167) between 2010 and 2013 were analyzed. Hematoma and edema volume during hospital stay were volumetrically assessed, and time course of edema evolution and peak edema correlated to hematoma volume, location, and surface to verify the strength of the parameters on edema evolution.ResultsOverall, 300 patients with supratentorial ICH were analyzed. Peak edema showed a high correlation with hematoma surface (R2 = 0.864, p < 0.001) rather than with hematoma volumes, regardless of hematoma location. Smaller hematomas with a higher ratio of hematoma surface to volume showed exponentially higher relative edema (R2 = 0.755, p < 0.001). Multivariable logistic regression analysis revealed a cutoff ICH volume of 30 mL, beyond which an increase of total mass lesion volume (combined volume of hematoma and edema) was not associated with worse functional outcome. Specifically, peak edema was associated with worse functional outcome in ICH <30 mL (odds ratio [OR] 2.63, 95% confidence interval [CI] 1.68–4.12, p < 0.001), contrary to ICH ≥30 mL (OR 1.20, 95% CI 0.88–1.63, p = 0.247). There were no significant differences between patients with lobar and those with deep ICH after adjustment for hematoma volumes.ConclusionsPeak perihemorrhagic edema, although influencing mortality, is not associated with worse functional outcomes in ICH volumes >30 mL. Although hematoma volume correlates with peak edema extent, hematoma surface is the major parameter for edema evolution. The effect of edema on functional outcome is therefore more pronounced in smaller and irregularly shaped hematomas, and these patients may particularly benefit from edema-modifying therapies.
