ABSTRACT

OBJECTIVE:

Colloid cysts (IIIVT CC) are benign neuroepithelial cysts located in the anterior third ventricle. The authors propose the use of NdYAG laser stereotactic neuroendoscopic for guided resection of the third ventricle colloid cysts.

METHOD:

Eleven patients presented third ventricle colloid cysts and were treated by NdYAG laser guided with stereotactic endoscopy (n=7) , stereotactic endoscopy (n=3) or stereotactly guided puncture (n=1). The patients were followed prospectively (average 33 months, range 19-64 months). The clinical data, neuroimaging findings, hospitalization stay, outcomes and complications of the method were evaluated.

RESULTS:

All patients presented headache; six had papilledema, one had gait disturbance and one had third-nerve palsy. Neuroimaging showed hydrocephalus and a IIIVT CC with 14.4-mm mean diameter. After surgery all patients presented clinical and image improvement. Only two patients presented transient morbidities that were easily treated One had diabetes insipidus that lasted for two days and was treated with a single dose of DDAVP, and another had chemical aseptic meningitis, probably due to the contact of the cyst content with the CSF. This patient was treated with antibiotics and corticosteroids with complete resolution of the problem without sequels. The other patients were discharged from the hospital 48 h after surgery.

CONCLUSION:

The stereotactic neuroendoscopy-guided procedure with NdYAG laser allowed the complete removal of the third ventricle colloid cysts, without definitive morbidities, sequels or recurrence of the lesion.
RESUMO

OBJETIVO:

Os cistos colóides (CC IIIVT) são lesões neuroepiteliais benignas localizadas anteriormente no terceiro ventrículo. Nós propomos a ressecção neuroendoscópica com o uso do NdYAG laser guiada por estereotaxia.

MÉTODO:

Onze pacientes portadores de cisto colóide do terceiro ventrículo foram tratados por neuroendoscopia estereotática com laser NdYAG (n=7), neuroendoscopia estereotática (n=3) ou punção estereotática (n=1) e foram seguidos prospectivamente (média 33 meses, variação 19-64 meses). Os dados clínicos, achados de neuroimagem, tempo de hospitalização, evolução e complicações referentes à técnica foram avaliadas.

RESULTADOS:

Todos pacientes apresentaram cefaléia; seis tiveram papiledema, um apresentou distúrbio de marcha e um apresentou paresia do terceiro nervo. Os exames de neuroimagem evidenciaram hidrocefalia e CC IIIVT com diâmetro médio de 14,4 mm. Depois da cirurgia todos os pacientes apresentaram melhora clínica e de imagem. Apenas dois pacientes apresentaram morbidades transitórias que foram facilmente tratadas um apresentou diabetes insipidus que durou dois dias e foi tratada com uma única dose de DDAVP, o outro apresentou meningite química asséptica, provavelmente pelo contato do conteúdo do cisto com o líquor. Este paciente recebeu antibióticos e corticóide com resolução completa do problema. Os outros pacientes receberam alta hospitalar após 48 h.

CONCLUSÃO:

A ressecção neuroendoscópica com o uso do NdYAG laser guiada por estereotaxia possibilitou a remoção completa do cisto colóide sem morbidades definitivas, seqüelas ou recorrência da lesão.
