Meningioma Resection

Meningioma usually occurs in the arachnoid cap-like cells around the nerve roots near the dura mater, which explains why meningioma is common in the lateral side of the spinal canal. Meningioma can also originate from fibroblasts of the soft or dura mater, suggesting that it may originate from mesoderm tissue. Meningioma grows out of the dura mater, mostly on the dorsal or lateral side of the spinal cord, and a few can be found in the ventral side of the spinal cord. Tumor resection should be performed once the meningioma is diagnosed. Treatment of diseases: spinal meningioma meningioma Indication Suitable for patients with meningioma. Contraindications 1. The general condition of the body is poor, there are cachexia or huge pressure sores or local skin bloated. 2. Aged and debilitated, the vital organs such as heart and lung are poor, and the limbs are completely paralyzed for more than 3 months. Preoperative preparation 1. Assess the patient's ability to withstand surgery and make necessary supplements and corrections. 2. Fasting 6~8h before surgery to prepare the skin in the operation area. Use before anesthesia. 3. Position the lamina segment where the lesion is located. In addition to the general positioning according to the body surface markers, the metal markers should be attached to the body surface before surgery to accurately position the X-ray. Surgical procedure 1. Anesthesia: general anesthesia with endotracheal intubation. 2. Position: Prone position or lateral position, neck segment tumor can also be used for sitting position. 3. Incision: Straight midline straight incision. 4. The spinal canal was revealed by conventional laminectomy. 5. Separate the tumor after cutting the dura. Meningioma is characterized by abundant blood supply, tight adhesion to the dura mater, and difficulty in separation. The tumor can be removed in the tumor first, the tumor volume is reduced, the tumor is separated from the spinal cord, and the cotton is isolated from the spinal cord. After the tumor base site is isolated, the tumor is removed along with the attached dura mater. 6. The resection of the meningioma in front of the spinal cord is difficult. You can cut off one or two dentate ligaments and gently retract the spinal cord to one side. The nerve roots involved in the tumor should be preserved as much as possible. After the tumor is revealed, the block is removed. If the dura mater attached to the tumor cannot be removed, bipolar electrocoagulation can be used to reduce tumor recurrence. Repair the dural defect with an autologous fascia or artificial dura mater. complication 1. Limbs are paralyzed. 2. Wound infection. 3. Corresponding to the nerve root pain or numbness of the limbal nerve root distribution area. 4. Postoperative hematoma. 5. Defecation dysfunction. 6. Abdominal distension and other gastrointestinal dysfunction.
