This article will introduce the key points of surgical resection of parasickle meningioma in the ** area. **Regional parafalx meningioma is a more common intracranial tumor located within the longitudinal fissure of the brain and may present with localized jerks in one lower extremity, or weakness or paresthesias in one lower extremity. Therefore, surgical resection needs to fully understand the morphology and characteristics of the tumor and the number and line of graft veins near the tumor, master the correct surgical skills and methods, and reduce the occurrence of complications to achieve the best results.
Below, we will introduce in detail the experience of resecting parafalx meningioma in the ** area:
1. Read the film carefully before surgery, and decide whether the surgical incision is located in front or behind the tumor according to the relationship between the tumor and the surrounding graft veins, so as to reduce the probability of graft vein injury as much as possible
2. Be careful when cutting the dura to avoid damaging the bridging vein or venous lake that flows into the dura and reduce the chance of postoperative venous bleeding
3. Give mannitol intravenous drip to reduce intracranial pressure before surgery, and after opening the dura, do not give the tumor to be removed, and release water from the longitudinal fissure as much as possible to further reduce the intracranial pressure, so as to have sufficient space to remove the tumor, avoid contusion of brain tissue, and prevent the occurrence of limb paralysis
4. The tumor is not large, and the brain sickle can be cut off directly, and the brain sickle involved in the tumor can be removed togetherIf the tumor is large, the tumor can be removed to lower blood pressure first, and then the affected brain sickle can be removed when there is space
5. During the resection of the tumor, it is necessary to pay attention to the bridging veins before, after, below and on the surface of the tumor, and separate them after decompression, so as to reduce the tension of the veins and avoid injury
6. If it is difficult to expose the tumor from the longitudinal fissure, the cortex of the motor area can be avoided and adsorb a brain area 2cm long before and after the proximal midline of the frontal lobe or parietal lobe, so as to expose the brain sickle and tumor
