Introduction
After meningioma surgery, cerebral edema may occur. The first critical period is the acute hemorrhage phase, which typically happens within 3 days after surgery, and during this time there is also a risk of seizures and infection. The second critical period is brain swelling, which usually occurs 7 to 10 days postoperatively. During this phase, it is essential to control cerebral edema to prevent severe consciousness impairment or even the development of brain herniation.
Generally, the critical period following brain tumor surgery lasts about 10 days, although recovery time may vary depending on the location of the surgery and the size of the meningioma.
Meningiomas are benign tumors; however, surgical treatment can cause some damage to brain tissue. Deep-seated meningiomas, in particular, carry a relatively high risk of bleeding, mainly because most meningiomas are closely adhered to surrounding brain tissue. After surgery, cerebral edema may develop, and in some cases, impaired consciousness may occur. Typically, patients pass through the critical phase within approximately 10 days after surgery. The first critical period is acute hemorrhage, which usually occurs within the first 3 days post-surgery, and there is also a risk of seizures and infection during this time. The second critical period involves cerebral swelling, which generally occurs 7 to 10 days after surgery. During this phase, it is essential to actively manage cerebral edema to prevent severe complications such as coma or the development of brain herniation.
After surgical treatment for meningioma, if the patient's symptoms and condition gradually stabilize and vital signs show progressive improvement, this generally indicates that the critical phase has been successfully passed.
