title: "Approaches and surgical results in the treatment of ventral thoracic meningiomas. Review of our experience with a postero-lateral combined transpedicular-transarticular approach.".
abstract: BACKGROUND
  The surgical treatment of anterior thoracic meningiomas provides a set of technical difficulties: the access is obstructed by the spinal cord posteriorly, thoracic cage and musculature laterally, mediastinum and pleural cavity anteriorly. It is fundamental to avoid any manipulation of the compressed, but also undamaged spinal cord: this shows significant plastic capabilities. Any effort should be directed to maximizing the contribution of the plasticity in order to obtain a good functional recovery.
  
  
  METHODS
  We have utilized a postero-lateral combined transpedicular-transarticular approach in order to obtain less invasiveness on the neural structures. Ten patients with ventral thoracic meningioma were operated in the last 5 years. The preoperative clinical evaluation, follow-up monitoring, timing of recovery, Clinical/Functional Grade change were analysed.
  
  
  RESULTS
  8 Patients had significant neurological improvement, 2 were unchanged. Magnetic Resonance Imaging (MRI) was useful in preoperative planning. Radical excision was possible in all patients and the late postoperative MRI did not reveal recurrence of the lesions at this time. To date, there has been no evidence of clinical or radiological instability.
  
  
  CONCLUSIONS
  We found this surgical exposure very helpful in the treatment of anterior thoracic meningiomas. The related morbidity and risk of instability are minimal. The combined postero-lateral approach offers a good surgical access to ventral, lateral and dorsal aspects of the thoracic spinal canal without manipulation of the spinal cord. Exposure is obtained by avoiding damage to the pleura and manipulation of the lungs and mediastinum and may be a feasible alternative in elderly patients, too.
