Microsurgery for spinal canal tumors: A clinical analysis of 145 cases / 第二军医大学学报

ABSTRACT

Objective: To explore the microsurgical treatment of spinal canal tumors and to analyze the strategies for clinical treatment of spinal canal tumors. Methods: Were retrospectively analyzed the clinical data of 145 patients with spinal canal tumors who were treated in our hospital from Dec. 2014 to Nov. 2016. Microscopic resection of tumors was performed with half lamina-, full lamina-, or lamina joint-fenestration. Spinal internal fixation was performed in 52 patients. The patients were followed up for 3-26 months. X-ray and magnetic resonance imaging were performed again in all patients, and computed tomographyed was performed in patients undergoing internal fixation. The spinal cord function was assessed by McCormick grade before operation, 1 week after operation and 3 months after operation. Results: Of the 145 patients, 127 underwent total resection, 16 underwent subtotal resection and 2 underwent partial resection. One patient with cervical intramedullary tumors developed kyphosis after operation and underwent reoperation. No screw rod dislocation or spine instability was found in the 52 patients undergoing spinal internal fixation. The McCormick grading was significantly better 1 week and 3 months after operation versus before operation (P<0.05). Conclusion: Microsurgery is an effective method for treatment of spinal canal tumors. Good intraoperative exposure and reliable spinal internal fixation are essential to reduce the complications after spinal canal tumor surgery.
