Pretreating cavernous sinus with hemostatic agent injection molding during endoscopic endonasal pituitary surgery:...

Area of Science:

• Neurosurgery
• Endoscopic Surgery
• Vascular Techniques

Background:

• Endoscopic endonasal pituitary surgery requires meticulous hemostasis, especially during cavernous sinus manipulation.
• Intracavernous bleeding can complicate pituitary adenoma resection, posing risks to patients.

Purpose of the Study:

• To elucidate the technical nuances of cavernous sinus molding with hemostatic agent injection.
• To evaluate the efficacy and safety of this technique for intraoperative bleeding control.

Main Methods:

• A cohort of 38 patients undergoing pituitary adenoma resection with cavernous sinus manipulation were included.
• A novel technique involving injection of a hemostatic agent into the cavernous sinus was employed prior to intracavernous procedures.
• Evaluation focused on intraoperative bleeding, surgical field quality, and postoperative complications.

Main Results:

• The technique effectively controlled intracavernous bleeding, with multi-spot injections showing superior results.
• Use of a specifically designed blunt metal tube facilitated precise injection.
• No significant postoperative complications such as temporal lobe edema or hemorrhage were observed.

Conclusions:

• Cavernous sinus hemostatic agent injection molding is a practical and effective adjunct for managing bleeding during endoscopic endonasal pituitary surgery.
• This technique offers a safe approach to controlling intracavernous bleeding, minimizing operative risks.
