Early brain hemorrhage clots are mainly present in the brain as blood clots and should not be absorbed. Around 1-2 weeks, the clot begins to gradually autolyze and liquefy. Around 2-3 months, it is broken down and absorbed by the infiltration of inflammatory cells. In patients with early-onset intracranial hemorrhage, if the bleeding is huge, the effect of taking a simple borehole drainage is not very obvious, mainly because of the early presence in the form of a blood clot. In order to achieve better decompression, the hematoma can only be removed by craniotomy. If the bleeding volume is not very large, borehole drainage can be performed in about 1-2 weeks, because at this stage the intracranial hematoma is completely liquefied. That is, according to the characteristics of its hematoma absorption, it can provide some theoretical basis for the treatment.
