Background And Objective: To analyze the location of familial retinal arterial tortuosity (fRAT) in the three-dimensional structure of retinal capillaries.

Patients And Methods: Retrospective observational study. Twelve eyes of six patients (two of whom were brothers) were imaged by optical coherence tomography angiography (OCTA).

Background And Purpose: To compare potential risk factors, clinical symptoms, diagnostic delay, and 3-month outcome between spontaneous internal carotid artery dissection (sICAD) and spontaneous vertebral artery dissection (sVAD).

Methods: We compared patients with sICAD (n=668) and sVAD (n=302) treated in 3 university hospitals.

Results: Patients with sICAD were older (46.

Background And Purpose: Isolated Horner syndrome without associated cranial nerve palsies or ischemic symptoms is an important presentation of spontaneous internal carotid artery dissection (sICAD). Ultrasound is often used as a screening method in these patients because cervical MRI is not always available on an emergency basis. Current knowledge on ultrasound findings in patients with sICAD presenting with isolated Horner syndrome is limited.

Background And Purpose: Cerebral atrophy has been recently recognized as a key marker of disease progression in cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). The contribution of subcortical cerebral lesions in this process remains undetermined. The aim of this study was to investigate the relationships between cerebral volume and different types of subcortical MRI lesions in CADASIL.

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy (CADASIL) is a hereditary arteriopathy caused by mutations of the Notch3 gene. The risk factors for cerebral microhaemorrhages (CM), their relationship to other MRI lesions in the disease and their potential clinical impact have not been previously defined. Our purpose was to examine the frequency, number and location of microhaemorrhages in a multicentre cohort study, defining predisposing factors and associated radiographic markers in CADASIL patients.

Diffusion tensor imaging can be used in vivo to assess the longitudinal and regional microstructural changes occurring after middle cerebral artery (MCA) infarcts in humans. Nine patients were investigated 1 week (D7), 1 (M1), 3 (M3), and 6 months (M6) after the occurrence of an isolated MCA infarction. First, an overall analysis was performed using histograms of mean diffusivity (MD) and fractional anisotropy (FA) in each hemisphere.
