Today, we are showcasing a complex neurosurgical procedure to remove a tumor located at the level of the second cervical vertebra (C2). In this video, Professor Talgat Kerimbayev, Head of the Spinal Neurosurgery Department at the National Center for Neurosurgery, explains the key features of the surgical technique.

Why is this surgery unique?

The C2 vertebra (axis) connects to the base of the skull and plays a crucial role in head movement. The tumor was located in a hard-to-reach area, close to vital structures — the spinal cord and the vertebral artery. Even the slightest error in this region can lead to irreversible consequences.

In standard practice, such surgery is typically performed in two stages:

Tumor removal via a transoral (through the mouth) approach;

Spinal stabilization using screw fixation.

What approach did our specialists take?

The spinal neurosurgeons, led by Professor Talgat Kerimbayev, applied an innovative modified technique — a single-stage removal of the tumor of the odontoid process through the vertebral pedicles, combined simultaneously with spinal stabilization using screw fixation.

This method allowed surgeons to avoid manipulation around the spinal cord and vertebral artery, achieve complete tumor removal, and eliminate the need for additional traumatic access.

As early as the second day after surgery, the patient was transferred to the ward and mobilized. The patient’s condition is stable and satisfactory, with positive clinical dynamics, and discharge is being planned.

It is encouraging to see high-tech medicine advancing in our country, enabling such precise and safe surgical interventions.
