Summary
Endoscopic treatment for congenital arachnoid cysts is effective, with most patients experiencing symptom relief and cyst size reduction. This minimally invasive approach is recommended as a first-line therapy.
Area of Science:
- Neurosurgery
- Pediatric Neurosurgery
Background:
- Congenital arachnoid cysts are benign fluid-collections that can cause neurological symptoms.
- Traditional treatments include open microsurgery or shunting, which are invasive.
Purpose of the Study:
- To evaluate the safety and efficacy of endoscopic treatment for congenital arachnoid cysts.
- To assess the outcomes of minimally invasive neurosurgery in a cohort of patients.
Main Methods:
- Prospective study of seven patients with congenital arachnoid cysts.
- Endoscopic cystocisternostomy and ventriculocystostomy performed via burr holes.
- Follow-up included clinical assessment and imaging (MRI/CT scans).
Main Results:
- Six out of seven patients showed cyst size reduction on imaging.
- Five patients experienced symptom relief, and one showed improvement.
- No mortality or significant morbidity was observed.
- One case required conversion to open microsurgery due to bleeding.
Conclusions:
- Endoscopic treatment is a safe and effective first-line option for congenital arachnoid cysts.
- Minimally invasive neurosurgery offers good outcomes with low complication rates.
- Microsurgical fenestration or shunting remain viable options if endoscopic treatment fails.
