Summary
Computer-assisted neurosurgical (CANS) navigation enhances transsphenoidal surgery safety. This system precisely guides surgeons, reducing risks like carotid artery injury during pituitary adenoma removal.
Area of Science:
- Neurosurgery
- Medical Technology
- Image-Guided Therapy
Background:
- Transsphenoidal surgery, used for pituitary adenomas, carries risks, including carotid artery injury.
- Experienced neurosurgeons face challenges in maintaining precise surgical orientation.
Purpose of the Study:
- To evaluate the efficacy of a computer-assisted neurosurgical (CANS) navigation system for transsphenoidal pituitary adenoma surgery.
- To assess the system's ability to improve surgical precision and safety.
Main Methods:
- The CANS system, utilizing electromagnetic coupling, displayed real-time suction tube position superimposed on preoperative MRI scans.
- The navigation system was employed during transsphenoidal approaches for nine pituitary adenomas.
Main Results:
- The CANS navigation system accurately displayed surgical orientation and provided localization in all nine patients.
- No intraoperative complications were reported during the use of the CANS system.
- Cerebrospinal fluid outflow during tumor removal may impact accuracy, necessitating precise probe positioning.
Conclusions:
- The CANS navigator enables precise suction tube localization during transsphenoidal approaches.
- This technology facilitates safer and less-invasive neurosurgical procedures for pituitary adenomas.
