It is partly difficult to relieve clinical symptoms after gamma knife surgery for conditions caused by bleeding from midbrain cavernous hemangioma. Midbrain cavernous hemangioma is a vascular malformation, due to the fragile wall of the corresponding blood vessel, it is easy to cause recurrent bleeding, which will cause edema of the surrounding brain tissues and lead to headache, dizziness, epilepsy and other symptoms. Gamma knife surgery can reduce the tumor size, deformation and narrowing of intratumor blood vessels and intratumor thrombosis, thus further reducing the occurrence of recurrent hemorrhage, but it cannot alleviate the clinical symptoms of the hematoma that has already appeared. If symptoms such as headache and dizziness are still present after the surgery, it is necessary to consult a doctor in time for standardized treatment under the guidance of the clinician.
