Filter by:The aim of the study was to determine retrospectively the presence of carotid artery calcification (CAC) detected on digital panoramic radiographs (DPRs) and correlate the finding of such calcifications with gender, smoking status, medical history and periodontal status.The authors hypothesized that more CACs could observed in DPRs of individuals with periodontitis and CACs may correlate with the various risk factors included age, gender, smoking status, medical history.DPRs, periodontal status, medical (hypertension, diabetes, hyperlipidemia, cardiovascular disease) and smoking stories of 1101 patients (576 males, 525 females) were evaluated. The patients were divided into two groups as CAC detected in dental DPRs [CAC(+)] and those who were not [CAC (-)]. Periodontal status categorized as gingivitis, periodontitis and gingivitis with reduced periodontium.
Despite aortic coarctation (CoA) repair these patients have cardiovascular complications and coronary artery disease is the most common cause of death.
The goal of this study is to evaluate the incidence of post procedure DW-MRI lesions (relative to baseline) and debris captured in the ENROUTE Transcarotid NPS inline filter during a transcarotid stenting procedure.
The goal of this evaluation is to document the incidence of post procedure DW-MRI lesions (relative to baseline) in patients treated with the transcarotid artery revascularization (TCAR) procedure.
The role of methylase system and Proprotein convertase subtilisin/kexin type 9 (PCSK9) in the accelerated atherosclerotic progression of diabetic patients is unclear. Authors will evaluate methylase activity and PCSK9 in carotid plaques of asymptomatic diabetic and non diabetic patients, as well as the effect of statin added to PCSK9 inhibitors (PCSK9i) therapy vs. statin alone in diabetic plaques. Plaques will be obtained from 43 type 2 diabetic and 30 non diabetic patients undergoing carotid endarterectomy. Diabetic patients will receive statin therapy (n 23) or statin plus PCSK9i (140 mg of evolocumab; n 20) or placebo (n 23) for 4 months before scheduled endarterectomy. Plaques will be analyzed for macrophages (CD68), T-cells (CD3), inflammatory cells (HLADR), methylase activity, nuclear factor (NF)-KB, tumor necrosis factor (TNF)-alpha, nitrotyrosine, matrix metalloproteinase (MMP) and collagen content (immunohistochemistry and enzyme- linked immunosorbent assay. Authors' study hypothesis is that methylase and PCSK9 over-activity will be associated with enhanced inflammatory reaction and NF-KB expression in diabetic plaques. Secondly, the inhibition of methylase activity in atherosclerotic lesions of diabetic patients by metformin plus SLGT2i might be associated with morphological and compositional characteristics of a potential stable plaque phenotype, possibly by down regulating NF-KB-mediated inflammatory pathways.
Sonodynamic therapy (SDT) is a new treatment for carotid atherosclerotic plaque. The purpose of this study is to evaluate the safety and initial effectiveness of this technique.
The objective of this post-market clinical follow-up study is to evaluate the clinical outcomes of patients receiving PhotoFix as a patch within a vascular repair or reconstruction procedure.
From our experience among Egyptian population in our institution, there is an increased prevalence of hidden subclinical peripheral artery disease along with carotid artery affection. Thus, increasing the risk of post-operative morbid complications.We aim to evaluate routine/ non-selective carotid and peripheral arterial screening in asymptomatic patients undergoing coronary artery bypass grafting in the Egyptian populationIt is a prospective, non-randomized, comparative study including two groups of patients. The study will start from the day of approval of the ethical committee. It will include 260 patients, on basis of "all new comers". Patients will be examined and classified as "high-risk" group (ɳ = 130) or "low-risk" group (ɳ=130). All patients will have the "routine" preoperative investigations along with evaluation of extracranial carotid system by non-invasive carotid duplex and lower limb arterial system by non-invasive bilateral lower limb arterial duplex.
Carotid revascularization procedures are performed for more than 87% of cases in patients with asymptomatic internal carotid stenosis (ICS), who are assumed to have a life expectancy of at least 5 years. Hence, the investigators aim to compare carotid artery stenting (CAS) with carotid endarterectomy (CEA) in terms of long-term prognostic endpoints in patients with uneventful perioperative course. CEA and CAS, as a consequence of either surgical trauma or mechanical stimuli related to the compliance mismatch between the stented segment and the native artery, may perturb carotid baroreceptors function causing an impairment of cardiovascular autonomic control. Also, CEA and CAS result in different postoperative geometric features of carotid arteries that entail relevant modifications of rheological parameters, that may be associated with the risk of local complications. Finally, long-term and sustained cognitive benefits after CAS as compared to CEA are yet to be demonstrated.
Background-White matter hyperintensities (WMH), patchy areas of hyperintense signal on T2-weighted or Fluid Attenuated Inversion Recovery sequences on brain magnetic resonance imaging (MRI), are believed to reflect cerebral burden of ischemic damage and are associated to incident stroke, dementia and eventually mortality in otherwise healthy subjects. Also brain atrophy has been related with presence of carotid atherosclerosis and vascular cognitive impairment. Carotid atherosclerosis may contribute to the genesis of WMH. A recent meta-analysis by our group comprising 5306 subjects was able to demonstrate an association between the presence of carotid atherosclerosis and WMH (odds ratio, OR, 1.42, 95% confidence interval [CI] 1.22-1.66). Objective-To evaluate the relation between carotid artery plaque characteristics, cardiovascular risk factors and brain atrophy/WMH burden analyzed quantitatively as number and volume of lesions and as brain volumes, and progression over 18 months of follow up in subjects asymptomatic for cerebrovascular disease with a carotid artery stenosis <70%.
