Review Case Reports
[Intrathoracic migration of a ventriculoperitoneal shunt catheter: a case report].
The intrathoracic complications from ventriculoperitoneal shunt placement are very rare. However, they are potentially serious if not treated. ⋯ All reports recommend early catheter repositioning into the peritoneal cavity after diagnosing the migration described, to prevent worse complications. Moreover, it is important to keep in mind that intrathoracic migration can happen and it is necessary to palpate the catheter continuously during passage through subcutaneous tunnelling to prevent it.

The insula is a highly connected area, as an intricate network of afferent and efferent projections connect it with adjacent and distant cortical regions. ⋯ the pars triangularis and orbicularis of the inferior frontal gyrus, as well as the middle and anterior part of the superior temporal gyrus, have few connections with the perisylvian associative network. Consequently, in the trans-opercular approach to the insula, these 2 regions represent anatomical corridors that give access to the insula. The IFOF and the uncinate fasciculus represent the deep functional margin of resection.

This study evaluates the pathological and magnetic resonance imaging evidence to define the precise topographical relationships of craniopharyngiomas and to classify these lesions according to the risks of hypothalamic injury associated with their removal. ⋯ A triple-axis topographical model for craniopharyngiomas that includes the degree of hypothalamus invasion is useful in planning the surgical approach and degree of resection. Infundibulo-tuberal craniopharyngiomas represent 42% of all cases. These lesions typically show tight, circumferential adhesion to the third ventricle floor, with their removal being associated with a 50% risk of hypothalamic injury. The endoscopically-assisted extended transsphenoidal approach provides a proper view to assess the degree and extension of craniopharyngioma adherence to the hypothalamus.

Review Historical Article
[The 2013 Sixto Obrador Award. A triple-axis topographical model for surgical planning of craniopharyngiomas. Part I: historical review of the topographical diagnosis and classification schemes of craniopharyngiomas].
This study reviews the historical evolution of pathological, neuroradiological and surgical evidence that influenced the topographical concepts and classification schemes of craniopharyngiomas. ⋯ A triple-axis topographical model for craniopharyngiomas that includes the degree of hypothalamus invasion is useful in planning surgical approach and degree of resection. The group of infundibulo-tuberal craniopharyngiomas associates the highest risk of hypothalamic injury (50%). The endoscopically-assisted extended transsphenoidal approach provides a proper view to assess the topography of the craniopharyngioma and its degree of adherence to the hypothalamus.

Review Meta Analysis
[Postoperative bed header position after burr-hole drainage of chronic subdural haematoma: systematic review and meta-analysis of randomised controlled trials].
Several studies have suggested the possible influence of postoperative bed header position on the risk of symptomatic recurrences and medical complications in patients who have been intervened due chronic subdural haematomas. Nevertheless, this hypothesis has not been assessed by a meta-analysis. ⋯ There were no differences regarding frequency of symptomatic recurrences, reoperations or medical complications in patients who were maintained in a flat position compared with those whose bed header was elevated during the postoperative course. Despite there being consistency between the results, there is a potential risk of bias; thus proscribing definitive recommendations until studies with higher methodological quality are available.
