A clinical study of a fibrinogen-based collagen fleece for dural repair in neurosurgery.
There is frequently a need for dural grafts to cover defects resulting from retraction, shrinkage, or excision following neurosurgical procedures. Many substances have been tried as possible dural substitution, and different tissues and materials have been evaluated for use in dural repair. ⋯ We conclude that TachoComb is a valuable alternative to the patients fibrous tissues for dural repair in cases in which autogenous tissues are either unavailable or insufficient for proper reconstruction.

Several models for the application of intra-operative magnetic resonance imaging (IMRI) have recently been reported, most of them unique. Two fundamental issues need to be addressed: optimal use of the scanner to ensure a wide base for research, development and clinical application, and an organisational model that facilitates such use. ⋯ Intra-operative MRI is an imaging tool that can be useful especially in the context of neuronavigation. A scanner that can be turned off during surgery is particularly appropriate for neurosurgery. The concept of joint use of such facilities with other clinicians is mutually worthwhile.

Case ReportsCerebral germinoma with hemiatrophy of the brain: report of three cases.
The authors report three cases of cerebral germinoma that occurred in young adults with unusual presentation. ⋯ Clinical diagnosis was not easy because of the unusual clinical presentations and atypical MR imaging findings. It is suggested that cerebral germinoma should be included in the differential diagnosis of a haemorrhagic mass which is associated with cerebral atrophy in the thalamus, basal ganglia, or internal capsule, especially in adolescents or young adults.

Basilar vasospasm following spontaneous and traumatic subarachnoid haemorrhage: clinical implications.
Cerebral vasospasm has been commonly described following subarachnoid haemorrhage (SAH) though its impact on neurological outcome, especially in head trauma, has not been yet elucidated. The purpose of this study was to monitor and correlate neurological condition and flow velocities (FVs) in the arteries of the brain after SAH and more particularly to investigate the influence of basilar artery (BA) vasospasm on neurological outcome. ⋯ The present results further support that BA vasospasm may act as an independent factor of ischaemic brain damage following SAH, especially in head trauma.

ReviewThe one-piece orbitozygomatic approach: the MacCarty burr hole and the inferior orbital fissure as keys to technique and application.
Use of the MacCarty keyhole burr hole and the inferior orbital fissure provides simplicity and safety to perform the one-piece frontotemporal orbitozygomatic (FTOZ1) approach. ⋯ Understanding the MacCarty keyhole burr hole and the microsurgical anatomy of the inferior orbital fissure is essential to performing the FTOZ1 approach. The three types of FTOZ1 approach enable the surgeon to tailor the approach according to the surgical exposure needed for each lesion.
