Carotid artery dissection (CAD) is a frequent cause of stroke, accounting for up to 25% of all ischemic strokes in young and middle-aged patients. It may be traumatic or spontaneous, with multi-factorial etiology. A tear in the arterial wall causes intrusion of blood within its layers, producing intra-luminal stenosis, or aneurysmal dilatation. Thrombo-embolism arising from this anatomic disruption has been postulated as the essential stroke mechanism in CAD. Bilateral internal carotid artery dissection (ICAD) has been rarely reported. Antiplatelets and anticoagulation remain standard therapy for CAD. However, in patients with either expanding pseudoaneurysms, severe flow compromise, worsening symptoms despite anticoagulation or contraindication to anticoagulation, endovascular stenting is beneficial. We describe a patient with ischemic stroke from spontaneous bilateral ICAD with completely occluded left ICA. Having failed medical therapy with antiplatelets and anticoagulants due to extensive loss of carotid vascular supply, he was managed successfully with endovascular stenting with good neurological recovery.

Programmable scanning diffuse speckle contrast imaging of cerebral blood flow.
Neurophotonics
January 2025
University of Kentucky, Department of Biomedical Engineering, Lexington, Kentucky, United States.
Significance: Cerebral blood flow (CBF) imaging is crucial for diagnosing cerebrovascular diseases. However, existing large neuroimaging techniques with high cost, low sampling rate, and poor mobility make them unsuitable for continuous and longitudinal CBF monitoring at the bedside.
Aim: We aimed to develop a low-cost, portable, programmable scanning diffuse speckle contrast imaging (PS-DSCI) technology for fast, high-density, and depth-sensitive imaging of CBF in rodents.
Is there a simple and accessible solution to improve acute infarct core imaging? The utility of steady-state CT angiographic source images obtained from a delayed phase acquisition.

Background: Early identification and quantification of core infarct is of importance in stroke management for treatment selection, prognostication, and complication prediction. Non-contrast computed tomography (CT) (NCCT) remains the primary tool, but it suffers from limited sensitivity and inter-rater variability; CT perfusion is inconsistently available and commonly blighted by movement artefact. We assessed the performance of a standardised form of CT angiographic source imaging (CTASI) obtained through addition of a delayed phase at 40 seconds post-contrast injection (DP40) following fast-acquisition CT angiography.

Department of Endocrinology, The Second Affiliated Hospital of Anhui Medical University, Hefei Anhui, 230601, China.
Background: The triglyceride-glucose (TyG) index has been identified as an alternative biomarker for insulin resistance (IR), while residual cholesterol (RC) is a simple, cost-effective, and easily detectable lipid metabolite. However, the associations of these two markers with carotid plaque presence remain unclear. Thus, this study aimed to explore their associations with carotid plaque presence.

Design & Methods: The study included 114 adolescents aged 12-17 years from Juiz de Fora, Brazil, divided into 40 individuals with obesity and 74 controls. Physical and biochemical assessments were conducted, including measurements of Brachial Flow-Mediated Dilation (BFMD), Carotid Intima-Media Thickness (IMT), and oxidative biomarkers such as nitrite, nitrate, and 8-isoprostane.
Transcirculation repair of a direct carotid-cavernous fistula in a patient who presented with hydrocephalus: illustrative case.
J Neurosurg Case Lessons

The Trauma and Neuroscience Institutes, St. John's Hospital and Medical Center, Tulsa, Oklahoma.
Background: Direct carotid-cavernous fistulas (CCFs) are relatively rare but dangerous complications of penetrating traumatic brain injury or maxillofacial trauma. A variety of clinical signs have been described, including ophthalmological and neurological ones. In some cases, severely altered cerebral blood flow can present as massive life-threatening bleeding through the nose, subarachnoid hemorrhage, and/or intraparenchymal hemorrhage.
