Cerebrovascular implications of takayasu arteritis: a review.

Purpose: Takayasu arteritis (TA) is a rare, chronic, inflammatory large-vessel vasculitis that affects the aorta and its main branches, including the cerebrovascular system. This review analyzes current knowledge and patient outcomes concerning the cerebrovascular implications of TA.

Methods: A literature search, with publications from 1994 to 2024, identified pertinent studies through PubMed.

Risk Factors for In-Stent Stenosis After Flow Diverter Treatment of Intracranial Aneurysms: A Systematic Review and Meta-Analysis of 2350 Patients.

Background And Objectives: Recent advances in flow diverter (FD) therapy for intracranial aneurysms have highlighted the need to evaluate risk factors for in-stent stenosis (ISS), a potentially serious complication. This meta-analysis aims to identify risk factors associated with an increased risk of ISS after FD treatment.

Methods: PubMed, Web of Science, Embase, and SCOPUS databases were systematically searched for studies reporting ISS rates and risk factors after FD therapy for intracranial aneurysms.

Management of Previously Failed Coiling and Clipping of a Middle Cerebral Artery Aneurysm.

Endovascular coiling techniques have emerged as an alternative and effective approach for treating intracranial aneurysms. However, in some cases, previously coiled aneurysms may require secondary treatment with surgical clipping, presenting a more complex challenge compared with the initial intervention. We present the case of a 39-year-old man with a residual class III Raymond-Roy occlusion partially coiled aneurysm at the left middle cerebral artery bifurcation (Video 1).

A unique anatomic variant: Left anterior choroidal artery arising proximal to fetal posterior communicating artery.

Anomalous vascular variants pose unique challenges in clinical management, especially in the context of neuroendovascular intervention. We present a case report detailing an extremely rare anatomic variant involving the left anterior choroidal artery, which arises proximal to the fetal posterior communicating artery. Our patient presented with confusion and speech abnormalities following a benzodiazepine overdose.

Bihemispheric ischemic strokes in patients with COVID-19.

Background: There is emerging evidence that COVID-19 can trigger thrombosis because of a hypercoagulable state, including large-vessel occlusion ischemic strokes. Bihemispheric ischemic stroke is uncommon and is thought to indicate an embolic source. Here, we examine the findings and outcomes of patients with bihemispheric stroke in the setting of COVID-19.
