Endoscopic transventricular resection of a colloid cyst

Area of Science:

• Neurosurgery
• Minimally Invasive Surgery
• Endoscopic Techniques

Background:

• Third ventricle colloid cysts are benign intracranial tumors.
• Surgical resection is the primary treatment for symptomatic cysts.
• Endoscopic approaches offer potential advantages over traditional open surgery.

Purpose of the Study:

• To demonstrate a purely endoscopic gross-total resection of a third ventricle colloid cyst.
• To highlight a specific surgical trajectory and technique for optimal approach.
• To emphasize the preservation of surrounding neurovascular structures.

Main Methods:

• Purely endoscopic approach utilizing a far lateral trajectory.
• Retraction of the caudate nucleus using an endoscopic sheath.
• Use of a pneumatic endoscope holder for bimanual manipulation.
• Intraoperative visualization and confirmation of gross-total resection.

Main Results:

• Successful gross-total resection of the third ventricle colloid cyst was achieved.
• The surgical technique preserved the fornix, thalamostriate vein, and caudate nucleus.
• Postoperative inspection revealed no signs of pressure-related damage to adjacent structures.

Conclusions:

• Purely endoscopic resection is a safe and effective method for treating third ventricle colloid cysts.
• The described technique provides an ideal approach with minimal disruption to critical neurovascular structures.
• Endoscopic surgery allows for complete cyst removal and preservation of neurological function.
