Purpose: Preoperative endovascular embolisation is a widely used adjunct for the surgical treatment of brain arteriovenous malformations (AVMs). However, whether this improves completeness of AVM resection is unknown, as previous analyses have not adjusted for potential confounding factors. We aimed to determine if preoperative endovascular embolisation was associated with increased rate of complete AVM resection at first surgery, following adjustment for Spetzler-Martin grade items.

This pilot randomised controlled trial (RCT) aims to determine the feasibility of answering this question in a main phase RCT.
Methods And Analysis: We will perform a pilot phase, parallel group, pragmatic RCT involving approximately 60 children or adults with mental capacity, resident in the UK or Ireland, with an unresected symptomatic brain cavernoma. Participants will be randomised by web-based randomisation 1:1 to treatment with medical management and with surgery (neurosurgery or stereotactic radiosurgery) versus medical management alone, stratified by prerandomisation preference for type of surgery.
Objective: Unruptured intracranial aneurysms (UIA) are common. For many the treatment risks outweigh their risk of subarachnoid haemorrhage and patients undergo surveillance imaging. There is little data to inform if and how to monitor UIAs resulting in widely varying practices.
View Article and Find Full Text PDFCerebral arteriovenous malformations (AVMs) are frequently associated with concurrent aneurysms. These aneurysms are commonly haemodynamically related to the AVM and can be classified into extranidal or intranidal in reference to the AVM nidus. An aneurysm arising from an artery that does not angiographically contribute to the blood flow to the AVM is uncommon.

Methods: A systematic review of the surgical treatment of IIH was carried out. Cochrane Library, MEDLINE and EMBASE databases were systematically searched from 1985 to 2014 to identify all relevant manuscripts written in English.
Background: Idiopathic intracranial hypertension (IIH) has an estimated incidence of one to three people per 100,000 people per year, and occurs most commonly in obese, young women. IIH is associated with severe morbidity, notably due to a significant threat to sight and severe headache. Several different management options have been proposed.

The publication rate of presented abstracts is considered a proxy marker of the scientific strength of a conference. We aimed to determine the publication fate of presented abstracts at SBNS meetings over a 5-year period.

Surgical simulation is increasingly proposed to help bridge the resultant training gap. For simulation training to translate effectively into the operating theater, acquisition of technical proficiency must be objectively assessed.

Despite being rare, brain abscess is a potentially fatal condition that requires early radiological and surgical intervention. It has a varied presentation, with many cases showing no localising typical features, making it hard to diagnose at presentation.

Purpose: To assess the incidence, risk factors, time of the onset, and effect of early evacuation of symptomatic SEH after spinal surgery.
Confident intra-operative localisation of thoracic spinal pathology remains challenging. Several strategies are routinely employed, including intra-operative fluoroscopy and pre-operative image-guided skin marking. These techniques are limited both by potential inaccuracy and inconvenience.

We illustrate a case of a traumatically ruptured vertebral artery pseudoaneurysm treated with coil embolisation.

We present a case of a 48-year-old man who was initially thought to have had a brainstem stroke and was clinically 'locked-in'. Upon investigation, a petrous apex dural atriovenous fistula was identified causing profound brainstem venous hypertension. Surgical clipping lead to complete neurological recovery.

Study Design: This study involved a search of MEDLINE (1966 to 2000), EMBASE (1980 to 2000), and the Cochrane Controlled Trials Register. The authors of the identified randomized controlled trials were contacted to detect any additional published or unpublished data. The trials selected for this study included all the truly unconfounded or quasi-randomized controlled investigations allocating patients with cervical radiculopathy or myelopathy to 1) "best medical management" or "decompressive surgery (with or without some form of fusion) plus best medical management," or 2) "early decompressive surgery" or "delayed decompressive surgery.
