[Treatment of lesions in mesencephalic aqueduct and around it by neuroendoscope].

OBJECTIVE: To explore the surgical efficacy of lesions in mesencephalic aqueduct and around it with neuroendoscope. METHODS: A total of 14 cases with lesion underwent neuroendoscope. Endoscopic third ventriculostomy (ETV), excision or biopsy and mesencephalic aqueduct plasty were performed. RESULTS: There were primary obstruction (n = 4), glioma (n = 4), intraventricular cysticercosis (n = 2), pineal cell tumor (n = 1), lymphoma (n = 1), brain abscess (n = 1) and germinoma (n = 1). Postoperative cranial computed tomography (CT) and/or magnetic resonance imaging (MRI) showed narrowed ventricle. The outcomes were symptomatic improvement (n = 5), no change (n = 5), worsening (n = 4) and mortality (n = 0). CONCLUSION: ETV, lesion biopsy or partial lesion resection and aqueductal plasty are efficacious for the patients with lesions in mesencephalic aqueduct and around it.
