After the formation of intracranial hematoma, the doctor has to monitor the patient’s vital signs, review the CT regularly, and dynamically observe the amount of intracranial hematoma, based on the amount of bleeding. When the bleeding volume reaches 30 ml or more above the curtain, craniotomy is performed. A subcurtain volume of 10 ml is an indication for surgery. There are various methods of intracranial hematoma removal: 1. The most common one is to open the skull and bone flap, determine the site of bleeding, open the cranial cavity, find the hematoma, and remove the hematoma, which is a traditional method; 2. Drilling and drainage, according to the CT picture, locate the site of the hematoma, drill the hematoma through a minimally invasive method, place a drainage tube, and inject drugs such as urokinase in the lumen to dissolve the hematoma, so that The hematoma is dissolved and turned into a liquid state, which is drained out of the body through the drainage tube. 3. Endoscopic hematoma removal. Different treatment modalities are chosen according to the condition, and the neurosurgeon should be consulted for details.
