Introduction: Current trend of neurosurgery at spine pathologies is to implement minimally invasive surgery. These types of approaches have been developed widely at any level of degenerative disease. This development has been associated with technology advances for minimally invasive techniques.

This approach is proposed as a treatment option for spinal compressive lesions as compared to traditional procedures, as it shows good results in terms of volume resection of the lesion, post-operative neurological outcome, low blood loss, less postoperative pain and decreased hospital stay.

Materials and Methods: We describe the surgical treatment technique in ten patients diagnosed with spinal intra-canal compressive lesions in the cervical, thoracic and lumbar region, which underwent surgical resection between January 2011 and July 2013. These were resected with a minimally invasive surgical technique in order to assess the surgical anatomy and feasibility of the approach to treat spinal lesions at this level.

Results: Ten patients were included for analysis. Meningioma was the most frequent neoplasm. There were no intraoperative complications. The means surgical time was 145 min. The average intraoperative bleeding was 188 ml. Patients experienced minimal postoperative pain and they were discharged in average 30 hours after surgery.

Conclusions: This type of approach technique provides adequate visualization and microsurgical resection of the lesions, with reduced muscle denervation and devascularization by preserving the tension of the ligament complex. These results correlate with previous studies of minimally invasive techniques for spinal neoplasms.
