Summary
Endoscopic surgery offers more procedures and visual control for periventricular lesions, while stereotactic biopsy provides a precise, smaller approach. Both minimally invasive techniques are safe and effective for diagnosis.
Area of Science:
- Neurosurgery
- Minimally Invasive Procedures
- Intracerebral Pathology Diagnosis
Background:
- Endoscopic and stereotactic surgery are established minimally invasive techniques for diagnosing intracerebral pathologies.
- Periventricular lesions present unique challenges for surgical assessment.
Purpose of the Study:
- To compare the specific advantages and disadvantages of endoscopic surgery versus stereotactic biopsy in evaluating periventricular lesions.
- To assess the diagnostic yield and safety profiles of each approach.
Main Methods:
- Retrospective analysis of 70 patients with periventricular lesions.
- 17 patients underwent endoscopic surgery; 55 underwent stereotactic biopsy.
- Two patients had both procedures.
Main Results:
- Endoscopic surgery achieved 100% diagnostic yield with opportunities for concurrent procedures (e.g., ventriculostomy, cyst fenestration).
- Stereotactic biopsy had a 98% diagnostic yield, with one patient requiring subsequent endoscopic biopsy.
- Hydrocephalus was more common in the endoscopic group (77% vs. 20%).
- Adverse events were low for both methods.
Conclusions:
- Endoscopic surgery allows for additional procedures and enhanced visual control, reducing injury risk.
- Stereotactic surgery offers a smaller approach with precise trajectory planning, often under local anesthesia.
- Both endoscopic and stereotactic approaches are safe and effective for periventricular lesions, with distinct benefits.
