YL-1 Needle Puncture vs BHC With Postoperative Exhaustive Drainage for CSDH

Chronic subdural haematoma (CSDH) is a common condition in neurosurgery. It is generally considered to be a closed exudate formed by blood or blood degradation products between the dura mater and the arachnoid membrane. Its local occupying effect will compress the neighbouring brain tissues, leading to varying degrees of neurological dysfunction. In severe cases, it can lead to cerebral hernia and endanger the patient's life. Currently, the most commonly used surgical method for the treatment of chronic subdural haematoma is BHC, but many studies have found that various complications may occur after BHC. With the rapid development of neurosurgical microtechnology, Twist Drill Craniotomy (TDC) was proposed. YL-1 puncture needle technique, as a modified solution of TDC, has a short surgical time and is less traumatic to patients. In the treatment of chronic subdural haematomas, investigator's team has adopted the strategy of postoperative instillation of urokinase and adequate drainage of the haematoma. Based on this, this study intends to conduct a multicentre prospective observational cohort study of the above two treatment in order to scientifically and rigorously derive the optimal clinical treatment strategy for chronic subdural haematoma.
