Transcortical Endoscopic Surgery for Intraventricular Lesions.

Area of Science:

• Neurosurgery
• Minimally Invasive Procedures
• Endoscopic Techniques

Background:

• Intraventricular lesions pose significant neurosurgical challenges.
• Traditional surgical approaches can involve substantial morbidity.
• Endoscopic techniques offer a less invasive alternative for accessing and treating these lesions.

Purpose of the Study:

• To review recent advancements in endoscopic techniques for treating intraventricular lesions.
• To evaluate the efficacy and outcomes of endoscopic procedures for specific conditions.
• To identify factors influencing the success of neuroendoscopic interventions.

Main Methods:

• A comprehensive literature search was conducted in PubMed for articles published since 2000.
• Keywords used included 'endoscopy,' 'endoscopic,' and 'neuroendoscopic.'
• Articles focusing on intraventricular lesions were selected and reviewed for relevant data.

Main Results:

• Endoscopic ventriculo-cysto-cisternostomy (VCC) showed better outcomes than ventriculo-cystostomy (VC) for suprasellar arachnoid cysts (SACs).
• Transforaminal-transchoroidal approach (TTA) may offer better exposure for colloid cysts compared to the transforaminal approach (TA).
• Endoscopic procedures alone can treat intraventricular cysticercosis, with third ventriculostomy potentially aiding cases with inflammation. Tumor biopsies achieve high diagnostic rates, but factors like tumor location and coagulation affect accuracy. Endoscopic tumor resection remains challenging.

Conclusions:

• Endoscopic procedures are effective for treating SACs and intraventricular cysticercosis.
• Endoscopy is a viable alternative for colloid cyst removal.
• While safe for tumor biopsies, endoscopic tumor resection requires further refinement.
