Ethmoidal dural arteriovenous fistulas are a rare entity accounting for 10 % of all dAVFs. Haemorrhage occurs in up to 91 % of cases, which is a particularly high risk and warrants therapeutic intervention. Endovascular treatment for these fistulas using the conventional detachable microcatheter technique is associated with certain limitations and risks; 8.
View Article and Find Full Text PDFPurpose: Intracranial arteriovenous malformations (AVMs) treated at our institution with modern techniques of endovascular intervention were analysed for the rate of complete occlusion, associated morbidity, and mortality. To our knowledge, this is the first series from the UK evaluating the effectiveness of endovascular embolisation as a primary treatment for selected cases.
Methods: All newly referred AVMs between January 2017 and June 2022 were reviewed and those treated with primary endovascular intervention were identified.
Purpose: Despite the potentially devastating and permanently disabling effects of paediatric arteriovenous malformations (pAVMs), there is a paucity of studies reporting long-term quality-of-life (QoL) outcomes in AVM patients. We aim to evaluate the management strategies for paediatric intracranial pAVMs in the UK and long-term QoL outcomes using a validated paediatric quality-of-life outcome measure.
Methods: In this single-centre case-series, we retrospectively reviewed a prospectively maintained database of all paediatric patients (i.
With increasing advances in technology, the breadth of aneurysms that are treatable via an endovascular approach has increased. Wide necked aneurysms remain difficult to treat but the emergence of dedicated intrasaccular flow disruption devices such as the Woven EndoBridge (WEB, Micorvention) has increasingly seen previously ruptured and unruptured wide necked aneurysms successfully embolised and secured from the circulation using a single device.We are reporting two cases of WEB device treatment from the earliest experience with this device at our institution.

We reviewed the screening practice for the detection of cerebrovascular disorder in asymptomatic children referred to our neurovascular service on the basis of a positive family history and parental and/or treating physician concern. Retrospective case-note review of referrals to our neurovascular service (July 2008-April 2018).

Methods: Retrospective case note and neuroimaging review of patients with angiographically confirmed DAVF diagnosed during January 2015-June 2020 at a tertiary neuroscience centre (Walton Centre NHS Foundation Trust, Liverpool, UK).
Results: Six intracranial DAVF causing cervical cord or brainstem oedema (all males aged 60-69 years) and 27 spinal DAVF (88% thoracolumbar) were detected over a 5.
Purpose: Since appearance of the balloon-remodeling technique and stent-assisted coiling, complex aneurysms have been treated successfully by endovascular means worldwide. Although these two techniques have been widely proven, the combination of both traditionally made the procedures more complicated technically. The aim of our study was to determine the technical success, safety, and efficacy of the low-profile stents delivered through double lumen balloons.

The uncommon location of the fistula and the absence of specific radiological signs resulted in initial misdiagnosis as longitudinally extensive transverse myelitis. Neurologists should have a high index of suspicion for dural arteriovenous fistula in older men, especially those with subacute or chronic symptoms, acellular cerebrospinal fluid and, particularly, if there is neurological deterioration soon after corticosteroid treatment.

Pseudoaneurysm can arise due to radionecrosis from previous radiotherapy in the base of skull and neck region and may present with haemoptysis many years later. It is important to be aware of this entity in the work-up of haemoptysis, particularly in patients with previous base of skull and neck radiotherapy.
View Article and Find Full Text PDFA retrospective review was made to assess the accuracy of four dimensional CT angiogram (4D-CTA) in diagnosis of arteriovenous malformations (AVM) and dural arteriovenous fistulas (DAVF), with catheter-based digital-subtraction angiogram (DSA) being gold standard. 33 pairs of investigations (DSA and 4D-CTA) were performed primarily for suspicion of AVM/DAVF. Based on blinded reports, sensitivity and specificity for detection of AVM/DAVF were 77% (95% CI: 46-95%) and 100% (95% CI: 83-100%) respectively.

The presence of associated aneurysms, especially intranidal aneurysms, is considered to increase the risk of re-hemorrhage. We present two cases where an intranidal aneurysm was demonstrated on four-dimensional CT angiography (time-resolved CT angiography) (4D-CTA).

The Comaneci device confers the same benefits as balloon remodeling but without the risks of parent artery occlusion. This alleviates time pressure on the clinician, and could reduce the risk of parent artery thrombosis.
