Magnetic resonance angiography (MRA) as well as intraarterial digital subtraction angiography (DSA) were performed in 45 patients suffering from cerebrovascular disease, both procedures within one week of each other. MRA und DSA were evaluated separately for every patient retrospectively by two experienced radiologists on consensus basis. The results were then compared using catheter angiography as gold standard. Evaluation was confined to the common and internal carotid arteries (CCA, ICA) in the neck subdivided into 5 grades of stenosis. A comparative assessment was impossible in 9% cases due to motion artifacts and patient malposition. Out of 18 verified CCA stenoses 13 were demonstrated by MRA and 39 out of 44 ICA stenoses were assessed by MRA. There was a highly significant correlation between degree of stenosis detected by the two methods. Spearman Rank correlation coefficients of 0.824 and 0.913 were found for CCA and ICA, respectively.

Proximal protection devices for carotid artery stenting - A benchtop assessment of flow reversal performance.

Background And Purpose: Proximal protection devices, such as TransCarotid Artery Revascularization (TCAR, SilkRoad Medical, Sunnyvale), aim to yield better outcomes in carotid artery stenting (CAS) than distal protection devices by preventing plaque embolization to the brain. However, transfemoral catheters may not fully reverse flow from the external carotid artery (ECA) to the internal carotid artery (ICA). We assess a new balloon-sheath device, Femoral Flow Reversal Access for Carotid Artery Stenting (FFRACAS), for this purpose.

Objectives: This study analyzed carotid artery remodeling characteristics in early carotid atherosclerosis (ECAS).
Methods: The 1021 participants were evaluated using ultrasonography and categorized into three groups: Group A, 391 participants with increased intima-media thickness (IMT); Group B, 300 participants with atherosclerotic plaque only on the carotid bulb (CB); and the control group (330 participants). The ratios of the diameters in the CB to those in the common carotid artery (D) and internal carotid artery (D) were defined as carotid index1 (CI) and 2 (CI).

The evaporation of drops on solid surfaces is a ubiquitous natural phenomenon, and their dynamics play a pivotal role in many biological, environmental, and industrial processes. However, the complexity of the underlying mechanisms has largely confined previous studies to liquid drop evaporation under atmospheric conditions. In this study, the first comprehensive investigation of the evaporation dynamics of conducting polymer-containing drops under controlled vacuum environments is presented.

Background: Extracranial carotid artery aneurysm (ExCAA) is a very rare pathology. However, due to local compression symptoms, risk of CNS ischemia, and the potential risk of rupture, it constitutes a significant clinical problem. The small number of cases, substantial differences in etiology and morphology, and various treatment methods of ExCAA disturb the analysis of this pathology.

Introduction: This study aimed to examine the relationship between the relative opening of the ICA (RO-ICA) and the structure of the ciliary cleft (CC) using Ultrasound Biomicroscopy (UBM).
Materials And Methods: Clinical data from 31 eyes of 17 dogs at the Veterinary Teaching Hospital of Chungbuk National University, Korea, were analyzed. RO-ICA was categorized as "Slightly Narrow", "Narrow", "Open", and "Wide Open", with eyes further grouped into "Narrow" (including Slightly Narrow and Narrow) and "Open" (including Open and Wide Open) for analysis.
