Background:
Giant thoracic disk herniations are calcified hernias that fill >40% of the spinal canal and result in myelopathy with associated neurologic symptoms. This is a fairly rare abnormality that requires surgical treatment. Currently, there is no unambiguous opinion about the surgical approach to the treatment for this pathology. It is believed that the most effective method is the anterior approach (minithoracotomy or thoracoscopic approach), which reduces the risks of spinal cord injury but is associated with the risks of damage to the lungs, pleura, and major vessels. A giant thoracic disk herniation is also quite large.
Methods:
We describe the case of a 60-year-old female patient with a giant thoracic disk herniation. Complete removal of the hernia through a minimally invasive dorsal approach was performed, followed by stabilization. In this case, we used 3-dimensional planning with the help of Surgical Theater, as well as intraoperative neuromonitoring. We also used the ZEISS QEVO, a microinspection tool to aid in resection.
Results:
No complications have been registered after the surgery. In this case, surgery resulted in a curative treatment outcome for the patient.
Conclusions:
The minimally invasive dorsal approach in the surgery of giant thoracic herniated disks can be successfully used in neurosurgical practice. With this approach, it may be possible to avoid dorsal stabilization, but this requires additional research.
