Abstract/OtherAbstract:
Early hematoma enlargement and delayed clot lysis contribute to brain injury after intracerebral hemorrhage (ICH). We investigated hematoma growth, clot lysis, and brain edema formation in patients with spontaneous ICH. A total of 17 spontaneous ICH patients who received regular medication were chosen for this study. All patients had their first CT scan within 5 hours of onset of symptoms (day 0). The patients then underwent second, third, and fourth CT scans at 1, 3, and 10 days later. Hematoma size and absolute and relative brain edema volumes were measured. Hematoma enlargement was defined as a > 33% increase in volume. Relative brain edema volume = absolute brain edema volume/hematoma size. Hematoma enlargement occurred in 4 of the 17 ICH patients (24%) within the first 24 hours. The hematoma sizes were reduced significantly at day 10 (p < 0.05) because of clot lysis. However, both absolute and relative brain edema increased gradually with time (p < 0.01). These results suggest that delayed brain edema following ICH may result from hematoma lysis. This study also shows that early hematoma enlargement occurs in Chinese patients with ICH. Reducing early hematoma growth and limiting clot lysis-induced brain toxicity could be potential therapies for ICH.
