The initial experience with the Embotrap III stent-retriever in a real world setting.

Materials And Methods: We performed a retrospective review of our prospectively maintained database to identify all patients treated with the Embotrap 3 stent-retriever between January 2021 and January 2022. We recorded the baseline demographics, NIHSS, ASPECT score and clot characteristics, first pass and final eTICI scores, complications and 90 day mRS.

Results: One hundred and ten patients met the inclusion criteria, average age 69 ± 14 years, 50% were male ( = 55).

The Q and A-The MIVI Q Catheters for Aspiration Thrombectomy-Initial Experience from London.

Background: Aspiration thrombectomy is a widely accepted treatment option for large vessel occlusion (LVO). The MIVI aspiration system has a novel design to maximize the lumen size. We present the results of our initial experience with this innovative aspiration thrombectomy system.

Vessel wall enhancement of a ruptured intra-nidal aneurysm in a brain arteriovenous malformation.

Ruptured arteriovenous malformations are a frequently encountered pathology with significant associated morbidity and mortality. Identifying and securing the rupture point is mandatory; however, this can often be difficult. Black blood vessel wall magnetic resonance imaging is a promising technique for identifying ruptured saccular aneurysms and has been used in cases of multiple aneurysms.

Dural masses: meningiomas and their mimics.

Meningiomas are the most common dural tumour. They are regularly being seen as an incidental finding on brain imaging and treated conservatively. However, there are many other dural masses which mimic their appearances, including primary neoplastic processes, metastases, granulomatous diseases and infection.

Sigmoid Sinus Diverticulum, Dehiscence, and Venous Sinus Stenosis: Potential Causes of Pulsatile Tinnitus in Patients with Idiopathic Intracranial Hypertension?

Background And Purpose: Pulsatile tinnitus is experienced by most patients with idiopathic intracranial hypertension. The pathophysiology remains uncertain; however, transverse sinus stenosis and sigmoid sinus diverticulum/dehiscence have been proposed as potential etiologies. We aimed to determine whether the prevalence of transverse sinus stenosis and sigmoid sinus diverticulum/dehiscence was increased in patients with idiopathic intracranial hypertension and pulsatile tinnitus relative to those without pulsatile tinnitus and a control group.

Subarachnoid haemorrhage guidelines and clinical practice: a cross-sectional study of emergency department consultants' and neurospecialists' views and risk tolerances.

Objectives: To establish if emergency medicine and neuroscience specialist consultants have different risk tolerances for investigation of suspected spontaneous subarachnoid haemorrhage (SAH), and to establish if their risk-benefit appraisals concur with current guidelines.

Setting: 4 major neuroscience centres in London.

Participants: 58 consultants in emergency medicine and neuroscience specialities (neurology, neurosurgery and neuroradiology) participated in an anonymous survey.

New vistas in clinical practice: susceptibility-weighted imaging.

Susceptibility-weighted imaging (SWI) is a recently developed magnetic resonance imaging (MRI) technique where image contrast represents 'magnetic susceptibility effects'-a natural property of tissues. The applications of SWI are rapidly increasing, with much work being carried out to determine the usefulness of the technique in multiple disease states. Current clinical applications of the technique include detection of microbleeds, subarachnoid hemorrhage (SAH), ferromagnetic deposition in neurodegenerative disease, and characterization of cerebral tumors.

Localized grey matter atrophy in multiple sclerosis: a meta-analysis of voxel-based morphometry studies and associations with functional disability.

Grey matter (GM) damage in Multiple Sclerosis (MS) occurs largely independent of white matter (WM) lesions and shows stronger correlation with clinical parameters than WM damage but no clear pattern of GM atrophy distribution has emerged in the literature. We used Signed Differential Mapping (SDM), a novel neuroimaging meta-analytical method, to assess global and regional GM volume differences in MS. Meta-regression methods were used to explore potential effects of disease duration and degree of functional disability.
