Aberrant anatomical variation of the vertebral artery (VA) from an internal carotid artery (ICA) is considered a rare finding. The incidence of this phenomenon can lead to patients suffering from posterior circulation neurological deficit if the ICA becomes significantly diseased. VA atypical anatomical origin is considered one of the rare pathologies, not only precipitating neurovascular incidents but equally leading to severe difficulty in VA dissection and surgical exposure, especially in carotid artery procedures.

Introduction: Dynamic vertebral artery insufficiency is a rare vascular phenomenon characterized by insufficient flow of the posterior cerebral circulation induced by dynamic motion of the head. Prior case reports have been limited to vertebral artery occlusion by cervical osteophytes or other structural impingements.
Case Report: In this case report, we discuss the unusual case of a 61-year-old female with a history of vertigo, diplopia, nystagmus, and left subclavian stenosis admitted to the hospital for syncope elicited by a left head turn and left shoulder raise.

Background Endovascular thrombectomy (EVT) is an effective method for vertebrobasilar artery occlusion (VBAO) in patients with moderate to severe deficits but has unclear benefits in patients with low National Institutes of Health Stroke Scale (NIHSS) scores at hospital admission. Purpose To compare the clinical outcomes of best medical management (BMM) alone versus BMM and early EVT (door-to-puncture time [DPT] ≤ 120 minutes) versus BMM and late EVT (DPT > 120 minutes) in patients with VBAO who have NIHSS scores of 10 or less at admission. Materials and Methods This retrospective study evaluated patients with VBAO and admission NIHSS score of 10 or less who were seen at 65 stroke centers in China from December 2015 to June 2022.

Background: To evaluate the prognostic effect of endovascular treatment (EVT) in patients with acute base artery occlusion (ABAO) within 24 h of onset, and analyze the factors related to prognosis.
Methods: A retrospective analysis was conducted on all ABAO patients who received EVT within 24 h of onset in the neurology department of Baotou Central Hospital in Inner Mongolia from May 2016 to October 2022. Good prognosis was defined as a Modified Rankin Scale (mRS) score of 0-3 and poor prognosis mRS score of 4-6 at 90 day follow-up, and factors related to prognosis were analyzed.

Background: Rotational vertebral artery occlusion, or bow hunter's syndrome (BHS), is a rare but clinically important cause of vertebrobasilar insufficiency. Extrinsic compression of the artery is usually caused by osteophytes, fibrous bands, or lateral disc herniation and typically occurs in the setting of anatomical variations, leading to dynamic compromise of the posterior circulation. Neoplastic causes of BHS are rare.
