Posterior Circulation Ischaemic Stroke

Abstract

About 20-25% (range 17-40%) of the 150 000 ischaemic strokes in the United Kingdom each year affect posterior circulation brain structures (including the brainstem, cerebellum, midbrain, thalamuses, and areas of temporal and occipital cortex), which are supplied by the vertebrobasilar arterial system. 1 Early recognition of posterior circulation stroke or transient ischaemic attack (TIA) may prevent disability and save lives, but it remains more difficult to recognise and treat effectively than other stroke types. Delayed or incorrect diagnosis may have devastating consequences, including potentially preventable death or severe disability, if acute treatment or secondary prevention is delayed. 2 The annual adjusted incidence of posterior circulation infarction was estimated at 18 per 100 000 person years (95% confidence interval 10/100 000 to 26/100 000) in an Australian study. 3 Preceding posterior circulation TIA or other transient brainstem symptoms, particularly if recurrent, signal a high risk of impending ischaemic stroke and should prompt specialist urgent referral for further management. 4 New acute treatment options and stroke prevention strategies specific to the posterior circulation are important areas of active research. This review aims to demonstrate the importance and challenges of recognising and treating posterior circulation stroke, including the key differences between posterior and anterior circulation stroke. What is posterior circulation ischaemic stroke?Posterior circulation ischaemic stroke is a clinical syndrome associated with ischaemia related to stenosis, in situ thrombosis, or embolic occlusion of the posterior circulation arteries-the vertebral arteries in the neck, the intracranial vertebral, basilar, and posterior cerebral arteries, and their branches (fig 1⇓). Common sites of occlusion cause characteristic clinical patterns and syndromes (figs 1 and 2⇓).

The clinical efficacy of Shenxiang Suhe Pill administration in posterior circulation ischemic vertigo: A randomized controlled trial

“…[8,9] TCD has become one of the most commonly used approaches in the diagnosis of vertigo. [3] Therapies for PCI includes antithrombotic, thrombolytic, and anti-arteriosclerosis treatment. Non-drug treatments for PCI includes application of endovascular technologies such as angioplasty, stent implantation, mechanical thrombectomy, and surgical method such as endarterectomy.…”

“…[ 2 ] PCI accounts for about 20% of ischemic cerebrovascular diseases, including transient ischemic attack and cerebral infarction in the posterior circulation. [ 3 ] Atherosclerosis is a chronic inflammatory disease and is considered as a major cause of PCI. [ 4 ] In PCI, immune cells interact to jointly regulate the formation of plaque and affect the tendency of specific plaques to rupture.…”

Association of composite dietary antioxidant index with prevalence of stroke: insights from NHANES 1999-2018

“…Dietary habits have garnered significant attention due to their direct influence on overall health. Extensive research over the years has established a compelling association between dietary choices and the incidence of stroke (12,13). Composite Dietary Antioxidant Index (CDAI) is a novel and comprehensive tool designed to assess the combined antioxidant intake from a diverse range of dietary sources (14).…”
