The difficulty of Elenna's surgery mainly involves three aspects.
First is the surgical posture in the supine position, which causes restrictions.
This position requires the patient to undergo a thoracotomy, severely interfering with the organs and causing the surgical window to be particularly narrow, limiting the space for maneuvering surgical instruments substantially.
Second is the intricate and complicated entanglement between the tumor and the neural fiber bundles within the spinal canal.
To avoid damaging the neural fiber bundles, the skill required for tumor excision is exceptionally high.
Third is the gradual or sudden positional changes of the tumor.
The gray matter of the spinal cord within the spinal canal is extremely soft.
As the tumor is gradually excised, the space created is slowly occupied by the spinal cord gray matter, causing the tumor to undergo shape changes.
As the surgery progresses, the changes in tumor shape become increasingly obvious.
