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.
