BACKGROUND: Duplex ultrasound is the first choice in diagnostics and surveillance of stenoses of the internal carotid arteries before and even after surgery. Therefore, the quality of duplex ultrasound is crucial to investigate these vascular pathologies. OBJECTIVE: Aim of this study was the evaluation whether different surgical techniques affect the postoperative quality of duplex ultrasound. METHODS: In a time period from January to May 2015 duplex ultrasound of the cervical vessels was performed in 75 patients after unilateral endarterectomy of the internal carotid artery at our department between 2006 and 2012...

BACKGROUND: Morphometric measurements of systemic atherosclerosis and direct quantification of visceral fat are only possible using materials from autopsy studies. However, the few autopsy studies that have investigated the association of visceral fat with atherosclerosis had small sample sizes and focused on coronary arteries of young or middle-aged White subjects. We aimed to investigate the association of pericardial fat (PF) and abdominal visceral fat (AVF) with atherosclerosis in the aorta, coronary, carotid, and cerebral arteries in a large autopsy study...

Cerebral hypoperfusion induced by transient bilateral common carotid arteries occlusion (tBCCAO), is associated with deleterious alterations in several physiological parameters of the animals. This study aims to investigate the effects of vanillic acid (VA) on memory impairment, locomotion and exploratory deficits, as well as histological and hippocampal long-term potentiation (LTP) injuries induced by tBCCAO procedure followed by reperfusion (BCCAO/R) in rats. Adult male Wistar rats (250-300g) were divided randomly into four groups: Sham-Operated group "Sham"; Vehicle+BCCAO/R group "BCCAO/R"; Vehicle+ Vanillic acid group "VA"; VA (100mg/kg) +BCCAO/R group "VA +BCCAO/R"...

Lifestyle modifications are recommended as the initial treatment for high blood pressure. The influence of dyslipidemia might be via moderate arterial stiffness, which results in hypertension and cardiovascular disease. We used data from a subgroup of the lifestyle, level of serum lipids/carotid femoral-pulse wave velocity (CF-PWV) Susceptibility BEST Study, a population-based study of community-dwelling adults aged 45-75 years. The serum lipid level and CF-PWV were measured at baseline, and lifestyle such as smoking status, sleeping habits, and the level of oil or salt intake was determined with the use of a validated questionnaire during follow-up...

Georgios Karaolanis, Konstantinos Maltezos, Chris Bakoyiannis, Sotiris Georgopoulos
Neck trauma is the leading cause of death mainly in younger persons posing to surgeons the dilemma whether to proceed with reconstruction of vascular injuries either in the presence of coma or in severe neurological deficit. Vascular injuries in zone II predominate over the other injuries located in zones I/III of the neck. Conventional open repair of carotid injuries with primary closure or interposition grafting is always recommended due to the effective long-term results for penetrating injuries or for patients unfit for endovascular intervention...

Objective: To evaluate in vivo patency rates of silk fibroin (SF) vascular grafts and resulting histological reactions in a canine model. Methods: To generate 3.5-mm inner diameter vessels, a combination of plaited silk fibers were wound with cocoon filaments and subsequently coated with an SF solution. The resulting SF grafts (n=35) were implanted into the carotid arteries of male beagles (age, 1-2 years; body weight: 9.0-10.5 kg). Expanded polytetrafluoroethylene (4-mm inner diameter, ePTFE) grafts (n=5) were used as controls...

A 74-year-old man with hoarseness was diagnosed with a right-sided aortic arch and Kommerell's diverticulum by computed tomography (CT). The diverticulum had a maximum diameter of 33 mm, and surgical intervention was chosen because of the possibility of rupture. A right common carotid to right subclavian artery bypass was constructed, stent-graft was placed after the branching of the right common carotid artery, and coil embolization of the diverticulum was performed via left brachial artery. No leaks were found on postoperative CT...

BACKGROUND: Apolipoproteins A-I and B (apoA-I and apoB) may be better indicators of the risk of cardiovascular and cerebrovascular diseases than conventional risk factors (RFs). The onset of ischemic stroke (IS) may be preceded by the development of atherosclerotic changes in carotid arteries, which can be detected by ultrasound. Only a certain % of patients with IS have an (underlying) carotid etiology. OBJECTIVE: The aim of our study was to determine the association between ultrasound indicators of carotid atherosclerosis and the presence of apolipoproteins and other biomarkers in patients with IS...

Atherosclerotic plaques are cholesterol-induced inflammatory niches accumulating in the vascular sub-endothelial space. Cellular and extracellular composition of human plaques is maneuvered by local inflammation that leads to alterations in the original vascular microenvironment and to the recruitment of an invading fibrous layer (fibroatharoma). In the present study we introduce a bioengineered three-dimensional model of human fibroatheroma (ps-plaque) assembled with a tailored hanging-drop protocol. Using vi-SNE based multidimensional flow cytometry data analysis we compared the myeloid cell-populations in ps-plaques to those in plaques isolated from human carotid arteries...

Examination of the common carotid artery (CCA) based on an ultrasound video sequence is an effective method for detecting cardiovascular diseases. Here, we propose a video processing method for the automated geometric analysis of CCA transverse sections. By explicitly compensating the parasitic phenomena of global movement and feature drift, our method enables a reliable and accurate estimation of the movement of the arterial wall based on ultrasound sequences of arbitrary length and in situations where state-of-the-art methods fail or are very inaccurate...

The 9p21.3 region is rich in regulatory elements and the variants in this region had been robustly associated with carotid plaque (CP) and coronary artery disease (CAD). Recently, the HACD4 was detected as one of the six 9p21.3 differentially expressed genes associated with accelerated atherosclerosis and greater mean lesion area in the Athsq1 congenic mice. We aimed to investigate association of two potentially regulatory HACD4 variants (rs36212560 I/D, rs2275888 T/C) and their haplotypes with CP occurrence and the level of HACD4 and FOCAD mRNA in human CP tissue...

OBJECTIVE: Ghrelin, a gastric hormone with pleiotropic effects modulates vascular function and may influence atherosclerosis. Plasma ghrelin is reduced in the metabolic syndrome (MS), which is also characterized by early atherosclerosis. Ghrelin circulates in acylated (AG) and desacylated (DAG) forms. Their relative impact and that of gender on subclinical atherosclerosis in MS is unknown. AIM OF THE STUDY: To investigate potential associations of total, AG and DAG with carotid atherosclerosis and with gender in the MS...

A 33-year-old man presented with aneurysmal subarachnoid hemorrhage from a ruptured, blister-type sidewall internal carotid artery (ICA) aneurysm. Balloon-assisted coiling was performed with residual neck. He subsequently developed severe vasospasm requiring intra-arterial therapies on multiple occasions, during which it was noted that despite widespread vasospasm, a focal segment of the ICA at the site of the aneurysm showed no significant spasm, suggesting underlying vessel abnormality. He was discharged without deficit and scheduled for flow diversion given concern over this potentially pathologic segment of vessel...

BACKGROUND AND PURPOSE: Small studies have suggested that Marfan syndrome is associated with a number of cerebrovascular complications. We sought to determine whether a clinical diagnosis of Marfan syndrome is associated with a higher prevalence of cerebrovascular diseases than the general population by performing a case-control study of hospitalized patients in the Nationwide Inpatient Sample (NIS). METHODS: Using the 2000-2012 NIS, we performed a case-control study matching cases of Marfan syndrome to controls without such a diagnosis...
