AI Article Synopsis
- Retinal artery occlusion can occur due to carotid artery stenosis, and it’s rare but possible during carotid artery stenting via the external carotid artery’s collateral circulation.
- Two cases were reported where retinal artery occlusion happened in patients after carotid artery stenting, suggesting the embolic debris came from the external carotid artery, which lacked protection.
- The study indicates that relying solely on a protection device for the internal carotid artery is insufficient, and it is crucial to also protect the external carotid artery to prevent retinal artery embolization.
Article Abstract
Retinal artery occlusion associated with carotid artery stenosis is well known. Although it can also occur at the time of carotid artery stenting, retinal artery occlusion via the collateral circulation of the external carotid artery is rare. We encountered two cases of retinal artery occlusion that were thought to be caused by an embolus from the external carotid artery during carotid artery stenting with a distal embolic protection device for the internal carotid artery. A 71-year-old man presented with central retinal artery occlusion after carotid artery stenting using the Carotid Guardwire PS and a 77-year-old man presented with branch retinal artery occlusion after carotid artery stenting using the FilterWire EZ. Because additional new cerebral ischaemic lesions were not detected in either case by postoperative diffusion-weighted magnetic resonance imaging, it was highly likely that the debris that caused retinal artery occlusion passed through not the internal carotid artery but collaterals to retinal arteries from the external carotid artery, which was not protected by a distal embolic protection device. It is suggested that a distal protection device for the internal carotid artery alone cannot prevent retinal artery embolisation during carotid artery stenting and protection of the external carotid artery is important to avoid retinal artery occlusion.

Background: Vascular dementia (VaD), the second most common cause of dementia, is characterized by cognitive decline due to reduced cerebral blood flow and blood-brain barrier disruption. Current evidence demonstrates that not only are VaD patients at higher risk of severe COVID-19 illness and mortality, but also that pre-existing cognitive dysfunction/dementia is associated with increased COVID-19 incidence. Conversely, SARS-CoV-2 infection alone worsens dementia-related mild cognitive impairment (MCI) and increases risk of cognitive decline, supported by similar fMRI findings demonstrating hypoperfusion.

In this report, a 37-year-old woman presented with a multi-nodular goitre with clinical features concerning for transient cerebral ischaemia. The anaesthetic management and neurological monitoring used to mitigate the risk of cerebral ischaemia during thyroidectomy is described and the literature surrounding this rare complication is explored.

Purpose: The present study aimed to compare the impacts of different exercise types on cardiovascular health and executive function in sedentary young individuals, and to determine the associations between cardiovascular function and executive function (EF) after exercise.
Methods: Sixty-three sedentary participants were randomly divided into high-intensity interval training (HIIT), moderate-intensity continuous training (MICT), resistance exercise (RE), and control groups. Macro- and microvascular endothelial function were assessed using brachial artery flow-mediated dilation and fingertip reactive hyperemia index, respectively.

Background: Studies have described a first pass effect (FPE) where patients with successful recanalization after one pass experience better outcomes. Few studies have evaluated this in patients with large core infarctions.
Objective: To determine whether patients with large core infarcts undergoing mechanical thrombectomy in which first pass reperfusion is achieved experience improved outcomes compared with those who undergo more than one pass.
