Wrapping of solitary ruptured intracranial aneurysms, outcome at five years.
Previous follow up studies of patients who have had ruptured intracranial aneurysms treated by a wrapping technique have largely been in the pre-microsurgical era. Our objective was to ascertain whether wrapping aneurysms with the aid of the operating microscope provides protection against rebleeding in the short and long term. The study involved retrospective analysis of patients with ruptured aneurysms treated by wrapping over a six-year period. ⋯ Of the 15 patients who had a solitary ruptured aneurysm wrapped, none had rebled at one year follow up. One patient died of a myocardial infarction at 4 years, the remaining 14 patients had no episodes of rebleeding with all patients achieving Glasgow outcome scores of four or five at 5 years follow-up. Although surgical clipping of intracranial aneurysms is the definitive method of treatment, our findings suggest that wrapping of ruptured intracranial aneurysms with the aid of the operating microscope confers good protection against both early and late rebleeding in those cases considered 'unclippable'.

Whole-body [18F]FDG PET in the management of metastatic brain tumours.
To determine its roles in the diagnosis and the systemic evaluation of metastatic brain tumours, whole-body positron emission tomography (PET) using [18F]FDG was performed in 20 consecutive patients. ⋯ It is suggested that whole-body [18F]FDG PET is a safe, reliable, and convenient method for the diagnosis and systemic evaluation of patients thought to be suffering or needing to be differentiated from a metastatic brain tumour.

Case ReportsThe natural history of late diagnosed or untreated growing skull fractures: report on two cases.
Growing skull fractures (GSF) are rare complications of head trauma. Cases after childhood are extremely rare and demonstrate complicated pathological conditions which necessitate extensive treatment. We report on two rare cases of intracranial cysts related to growing skull fractures which are secondary to trauma sustained during childhood, and have been discovered in adolescence.

Comparative StudyA comparison between ventriculo-peritoneal and ventriculo-atrial cerebrospinal fluid shunts in relation to rate of revision and durability.
Results of 884 first-time shunts inserted in the time period from 1958 to 1989 are retrospectively evaluated, 1) to perform a durability analysis of a shunt based on Kaplan-Meyer method, 2) to compare the rate of revision for ventriculo-atrial (VA) and ventriculo-peritoneal (VP) shunts, 3) to compare the durability of a VA shunt with a VP shunt and 4) to do a stratified durability analysis comparing the VA and VP shunts in relation to the following background variables: shunt type, time period and age of the patient. Furthermore the specific complications related to VA and VP shunts are identified based on findings in the literature. Overall one-year shunt durability is 57% and five-year shunt durability is 37%. ⋯ Hence the apparent difference in revision rate between VA and VP shunts seems secondary to variations in follow-up time and variations in background variables. To supplement our statistical analysis we have performed a literature study to look at the specific complications associated with VA and VP shunts. It seems as if the specific complications in relation to the VA shunting method are more severe than in relation to the VP shunting method.

The Camino intracranial pressure device in clinical practice: reliability, handling characteristics and complications.
Intracranial pressure monitoring has a key role in the management of patients developing increased intracranial pressure (ICP). We adopted the Camino fiberoptic system for intracranial pressure measurement in 1993 in our neurosurgical department. The aim of this study was to investigate reliability, handling characteristics and complication rate of the Camino intracranial pressure device. ⋯ Recorded complications included infection (0.7%), intraparenchymal haematoma (5.1%), and a high complication rate (23.5%) with regard to technical aspects. The Camino intracranial pressure system offers reliable ICP measurements in an acceptable percentage of devices, and the advantage of in vivo recalibration. The high incidence of technical complications identifies a need for improvement in the fiberoptic cable and the fixation system.
