Natural history of dolichoectatic vertebrobasilar aneurysms: a multinational study.

Objective: Dolichoectatic vertebrobasilar aneurysms (DVBAs) are expansions of arterial tissue leading to aneurysmal formations without an obvious neck. Their natural history is poorly understood; usually patients are admitted with thromboembolic complications and/or neurological symptoms from the mass effect. There have not been international collective data, and correct timing for highly risky treatments has been under discussion.

Frequency of subclavian steal syndrome in a sample of non-Western population.

Background: Subclavian steal syndrome (SSS) is not rarely found during ultrasound examinations. Previous reports demonstrated a relation between ethnic factors and SSS. Data regarding SSS in non-Western population are still lacking.

Endovascular therapy for acute vertebrobasilar occlusion (VERITAS): a systematic review and individual patient data meta-analysis.

Background: Trials of endovascular therapy for basilar artery occlusion, including vertebral occlusion extending into the basilar artery, have shown inconsistent results. We aimed to pool data to estimate safety and efficacy and to explore the benefit across pre-specified subgroups through individual patient data meta-analysis.

Methods: VERITAS was a systematic review and meta-analysis that pooled patient-level data from trials that recruited patients with vertebrobasilar ischaemic stroke who were randomly assigned to treatment with either endovascular therapy or standard medical treatment alone.

Babinski-Nageotte syndrome after vertebral artery dissection and foramen arcuale.

Vertebrobasilar ischaemia happens for a myriad of reasons. Among the rarest is the existence of a foramen arcuale (FA). This condition results from the ossification of the lateral edge of the posterior atlantooccipital membrane, closing, completely or partially, the top of this groove, turning it into a foramen or a channel.

Bow Hunter's Stroke Caused by Cryptic Recanalization of an Occluded Vertebral Artery: A Case Report.

An 80-year-old man was admitted to our hospital with acute cerebellar infarction. Conventional magnetic resonance angiography and computed tomography angiography (CTA) showed occlusion of the right vertebral artery (VA). Carotid ultrasonography revealed that the right VA was narrowed at its entry point into the transverse foramen near C6.

Impact of tortuosity of the V1-segment vertebral artery on mechanical thrombectomy.

Tortuosity of the vasculature poses challenges to mechanical thrombectomy (MT); however, only a few studies have reported the impact of vertebral artery (VA) tortuosity on MT. The present study aimed to investigate the impact of tortuosity of the V1-segment VA on MT in patients with acute vertebrobasilar artery occlusion (AVBAO). The patients diagnosed with AVBAO and treated with MT in the Stroke Center of Xijing Hospital from November 2019 to March 2022 were analyzed retrospectively.

Outcomes of stenting after failed basilar artery thrombectomy for acute stroke: a nationwide registry-based cohort study.

Background: Mechanical thrombectomy is the most effective treatment for restoring reperfusion in large vessel occlusion acute ischaemic stroke, even in patients with posterior circulation. However, the strategy for optimal treatment of patients with acute basilar artery occlusion (BAO) in difficult-to-treat cases in which thrombectomy has failed is unknown.

Aims: The purpose of this study was to evaluate the clinical efficacy and safety of rescue intracranial stenting (RIS) in patients with acute BAO treated with thrombectomy.

Wallenberg Syndrome Secondary to Vertebrobasilar Aneurysm Associated With Subclavian Steal Syndrome.

Wallenberg syndrome, also known as lateral medullary syndrome, is a rare condition affecting the vertebrobasilar circulation, causing symptoms such as vertigo, nystagmus, dysarthria, and hemifacial weakness. Typically linked to ischemic strokes, it can also arise from vertebrobasilar aneurysms. In rare cases, subclavian steal syndrome (SSS), involving retrograde flow in the vertebral artery due to subclavian stenosis, complicates the picture, as observed in this case of a 66-year-old woman with both conditions and a vertebrobasilar aneurysm.

Evaluation of the effect on stroke mechanism, stroke recurrence and clinical outcome in stroke patients with basilar artery atherosclerosis: A single centre retrospective observational study.

Objectives: Basilar artery atherosclerotic plaque is the predominant cause of stroke in the posterior circulation. İscheamic stroke caused basilar artery atherosclerosis faces a high risk of recurrence despite optimal medical treatment, which might lie in the less than ideal recognition of underlying stroke mechanism and lack of individualized treatment for strokes of different mechanisms. We aim in this study to investigate the effect on stroke mechanism, stroke recurrence and clinical outcome in stroke patients with basilar artery atherosclerosis.

Hyperintense vessel sign in vertebrobasilar dolichoectasia.

Vertebrobasilar dolichoectasia (VBD) is a rare condition characterised by ectasia, elongation and tortuosity in the vertebrobasilar arteries. VBD prevalence ranges from 0.05% to 18%.

Endovascular treatment for aggressive vertebrobasilar stenosis due to giant cell arteritis: illustrative cases.

Background: Giant cell arteritis (GCA) infrequently presents with progressive symptomatic vertebrobasilar stenosis. Vertebrobasilar GCA is often refractory to medical treatments and can lead to short-term ischemic stroke recurrence, which is associated with a poor prognosis. Endovascular treatment (EVT) is a therapeutic option; however, the optimal timing and indications for its application remain unclear.

Basilar Artery Band Thrombus: Report of a Unique Case.

Basilar artery bands (BAB) are described in scant reports in the literature as shelves, bridges, septa, or webs within the lumen of the basilar artery. The anatomy and histology of these bands have only recently been fully explored and classified. Although there has been evidence of non-atherosclerotic calcification of these structures and vertebrobasilar atherosclerosis, previous studies have not demonstrated any plaque or thrombus formation on the basilar artery bands.
