The Camino ICP sensor remains one of the most popular ICP monitoring devices for use in critical neurosurgical patients. The system offers reliable ICP measurements in an acceptable percentage of device complications and the advantage of in vivo recalibration. The incidence of technical complications was low and similar to others devices.

SummaryBackground. Intraventricular meningiomas are rare tumours that represent about 2% of all intracranial meningiomas, and represent one of the most challenging problems in neurosurgery. They are located deep within the brain and often are sizable and highly vascular. We report on a series of 10 meningiomas of the lateral ventricles treated at our institution during the last 28 years.Patients. Ten patients (6 women, 4 men; mean age 41.6 yrs) were admitted to our medical center between 1978-2005 with meningioma of the lateral ventricles. Headache was the first symptom in 8 cases and ocular signs were present in 5 patients.Results. Seven tumours were located in the right ventricle (70%) ranging in size from 2-8 cm, with 7 tumours larger than 3 cm in diameter. Nine patients underwent surgery with total excision in 8 cases and subtotal in the other; the remaining patient only received radiosurgery.Conclusions. Total resection is the gold standard for treatment which was possible in all but one of the cases undergoing surgery. Resultados. El síntoma de debut fue la cefalea en 8 casos y en 5 pacientes existían alteraciones oculares. Siete tumores estaban localizados en el ventrículo derecho (70%) con un tamaño que oscilaba entre 2 y 8 cm.; 7 tumores tenían más de 3 cm. de diámetro. Se intervino quirúrgicamente a 9 pacientes consiguiéndose una extirpación completa en 8 casos y subtotal en el otro; el paciente restante fue tratado mediante radiocirugía estereotáctica.Conclusiones. La resección completa es el tratamiento idóneo en los meningiomas intracraneales, que exceptuando un caso fue posible en todos nuestros pacientes operados.PALABRAS CLAVE: Abordajes quirúrgicos.
