Cerebral puncture is often used in clinical practice, and it is important to clarify the specific condition at the time of the cerebral puncture, such as CT-guided intracranial hematoma puncture and drainage for cerebral hemorrhage, or extracerebral ventricular puncture and drainage for acute hydrocephalus.CT-guided intracranial hematoma puncture and drainage is a minimally invasive procedure that has become popular in recent years, and it often requires only minimally invasive drill holes placed inside the cavity of a hematoma with CT localization guidance. A minimally invasive drilling approach is performed and a catheter is placed in the hematoma cavity to allow for proper removal of the intracranial hematoma. This procedure has fewer complications and is less invasive, and is indicated for older patients or those with less bleeding, and the results are excellent. Extraventricular puncture and drainage surgery, on the other hand, is mainly indicated for acute hydrocephalus formation, which requires immediate drainage of intracranial fluid thus reducing the state of intracranial hypertension, and is a life-saving treatment modality for patients.
