Short communication: Retrospective analysis of obligatory testing results for Equine virus arteritis reveals a decrease of its seroprevalence in stallions used for artificial insemination.

Equine viral arteritis (EVA) can induce a persistent carrier state in stallions which then shed the virus via semen. About 30 years ago, obligatory EVA testing of stallions used for artificial insemination (AI) was implemented in the European Union. Information on the efficacy of these regulations on the prevalence of EVA in stallions are not yet available.

Balloon assisted Woven endobridge deployment (BAWD): A safety and efficacy study.

Background: Balloon-assisted deployment/remodelling is a proven adjunctive technique for coil embolization of intracranial aneurysms, and it may be a helpful adjunct in delivering the Woven EndoBridge (WEB) device.

Objective: To evaluate the safety, efficacy and feasibility of balloon-assisted WEB deployment in both ruptured and unruptured intracranial aneurysms in both typical and atypical locations.

Methods: Patients who underwent treatment of ruptured and unruptured intracranial aneurysms with the BAWD technique were retrospectively identified from a prospectively maintained database at two neurointerventional centres.

'Diagnostic anchoring' and a delayed diagnosis of reversible cerebral vasoconstriction syndrome.

We present a case of a woman in her 60s with acute left hemispheric ischaemic stroke syndrome due to tandem occlusions of the proximal left internal carotid artery and left middle cerebral artery. This was treated with emergent carotid artery stenting and endovascular clot retrieval. The patient made a complete recovery and was discharged home only to represent a few days later with focal neurological symptoms, profound headache and labile blood pressure.

Prior anticoagulation and bridging thrombolysis improve outcomes in patients with atrial fibrillation undergoing endovascular thrombectomy for anterior circulation stroke.

Background: Where stroke occurs with pre-existing atrial fibrillation (AF)studies validating the safety and efficacy of bridging thrombolysis, and the use of endovascular thrombectomy (EVT) in the setting of prior anticoagulation, are limited to single-center reports.

Methods: In a retrospective analysis, AF patients undergoing EVT for anterior circulation large vessel occlusion stroke enrolled in a prospectively-maintained, international multicenter database (International Stroke Perfusion Imaging Registry (INSPIRE)) between 2016 and 2019 were studied. Patients were categorized by anticoagulation status: anticoagulated (warfarin/non-vitamin K oral anticoagulants) versus not anticoagulated.

Urgent computed tomography angiography in paediatric stroke.

Aim: To improve delivery of acute therapies for acute ischaemic stroke (AIS).

Method: We identified factors influencing the speed of diagnosis and delivery of acute therapies in a prospective cohort of 21 children with suspected AIS (eight with AIS, 13 stroke mimics) and explored them in a retrospective cohort with confirmed AIS.

Results: Approximately half of the prospective and total AIS cohorts presented with acute, sustained hemiparesis, and were diagnosed relatively quickly.
