Background: In patients who have suffered a transient ischemic attack (TIA) or ischaemic stroke, diagnostic imaging often reveals an occlusion in the extracranial internal carotid artery (ICA) on the symptomatic side. It is generally assumed that no follow-up is needed.
Case Description: A 57-year-old man reported to the emergency department with global aphasia. Two weeks previously he had been diagnosed with an occlusion of the left ICA following a TIA. On the basis of CT angiography we diagnosed an ischaemic stroke in the left middle cerebral artery territory and a severe stenosis of the left ICA. Several days later the patient underwent a successful carotid endarterectomy.
Conclusion: Following an acute symptomatic occlusion of the extracranial ICA, recanalisation of the artery can take place. In these patients we advise considering a repeat of the diagnostic imaging of the ICA within a week.

Purpose: To describe a case in which a right replaced posterior cerebral artery (PCA) was associated with an ipsilateral superior cerebellar artery (SCA) type persistent trigeminal artery (PTA) variant.
Methods: A 53-year-old man who had been diagnosed with chronic dissection of the left vertebral artery (VA) 4 months previously underwent follow-up magnetic resonance (MR) angiography using a 3-Tesla scanner.
Results: MR angiography showed a slightly dilated left VA at the terminal segment without interval change.

Trimethylamine -oxide (TMAO), a gut microbiome-derived metabolite, participates in the atherogenesis and vascular stiffening that is closely linked with cardiovascular (CV) complications and related deaths in individuals with kidney failure undergoing peritoneal dialysis (PD) therapy. In these patients, arterial stiffness (AS) is also an indicator of adverse CV outcomes. This study assessed the correlation between serum TMAO concentration quantified with high-performance liquid chromatography and mass spectrometry and central AS measured by carotid-femoral pulse wave velocity (cfPWV) in patients with chronic PD.

Background: Previous trials have failed to demonstrate the benefits of extracranial-intracranial (EC-IC) bypass surgery for patients with carotid or middle cerebral artery occlusion. However, little evidence has focused on the effect of age on prognosis. This study aimed to explore whether EC-IC bypass surgery can provide greater benefits than medical therapy alone in specific age groups.

Carotid artery stenosis is a significant cause of ischemic stroke, often necessitating interventions like carotid artery stenting (CAS) to restore adequate blood flow. However, complications like intraprocedural arterial dissection can arise during the procedure. This report presents a case of intraprocedural arterial dissection during CAS using a CASPER Rx stent.

Peripheral endothelial function, which accounts for the variability in shear stimulus, can be assessed using shear-mediated dilation normalized to the increased shear stimulus. Similarly, shear-mediated dilation of the internal carotid artery (ICA), an index of cerebrovascular endothelial function, should be normalized to increased shear stimulus. However, this approach has not yet been validated.
