- Original description
Cerebrospinal fluid is a clear fluid that surrounds and protects the brain. During surgery for brain tumors, neurosurgeons often need to open the covering of the brain (the dura) to reach the tumor. At the end of the operation, this covering is carefully closed again. In some cases, the closure might not be completely adequate leading to cerebrospinal fluid leak. This leakage may collect under the scalp or flow out through the surgical wound. When this happens, the surgical wound may not heal properly, and the risk of infection can increase. These complications can delay recovery and may postpone additional treatments, such as radiotherapy or chemotherapy, that are often needed after brain tumor surgery. Although cerebrospinal fluid leakage is less common after supratentorial craniotomy (surgery on the upper part of the brain) than after other types of brain surgery, it remains a challenging complication and has not been well studied in this group of patients. The aim of this study is to determine how often cerebrospinal fluid leakage occurs after supratentorial craniotomy for intracranial tumors, identify factors that increase the risk of leakage, and evaluate how these leaks are managed. Understanding these factors may help reduce the occurrence of cerebrospinal fluid leakage and improve postoperative recovery in the future.Read full original descriptionShow less
Cerebrospinal Fluid Leak Incidence, Management and Risk Factor After Supratentorial Craniotomy for Intracranial Tumors: a Prospective Observational Study.
