Abstract
OBJECTIVE: The aim of this study was to evaluate the safety and efficacy of microscopic minimally invasive keyhole technique for surgical resection of thoracic spinal meningiomas.
METHODS: Seventeen consecutive patients with thoracic spinal meningiomas were included in the series from May 2015 to August 2017. All patients were treated using a microscopic keyhole technique through a tubular retractor system. The demographic data, perioperative variables were recorded. At last follow-up, clinical outcome was assessed using the visual analog scale (VAS) for pain and the American Spinal Injury Association (ASIA) scale for motor/sensory outcome.
RESULTS: All of them underwent microscopic keyhole surgery and complete resection was achieved. Mean operative time was 153.2 min (range115-300 min). Mean blood loss during surgery was 110.3mL (range 50-175mL). No infection or aggravation of spinal cord injury occurred after operation, except for two patients who had postoperative cerebrospinal fluid leakage that recovered after conservative treatment. The mean duration of hospital stay was 6.8days(range5-10 days). At the last follow-up, all patients had a reduced level of pain as suggested by an average VAS score that improved from 7.6 to 0.2. The ASIA grade improved or remained normal in all patients except one. No evidence of tumor recurrence or secondary spinal deformity was observed in any patients during the postoperative follow-up period, and spinal stabilities were found to be satisfactory.
CONCLUSIONS: Based on our results, the microscopic minimally invasive keyhole technique can be used safely and effectively for resection of thoracic spinal meningiomas.
