Hyperhomocysteinemia is implicated in retinal neurovascular illnesses including arterial occlusive disease, venous occlusive pseudoexfoliation and disease glaucoma. research to elucidate systems of HHcy-linked retinal disease. A medically relevant experimental program may be the mouse deficient or inadequate the gene encoding CBS enabling studies of the consequences of gentle to serious endogenous elevation of Hcy [30]. In prior studies, we analyzed implications on retina function and framework using either mice, that have a much milder HHcy with ~4C7 collapse upsurge in plasma Hcy (and a 2-collapse upsurge in retinal Hcy) and a standard lifespan. Our function shows that both mice possess retinal neuronal disruption and participation from the retinal vasculature [31C36]. To understand systems for HHcy-induced retinal neuronal loss of life we previously looked into the function of excitotoxicity and oxidative tension using perforated patch clamp evaluation and fluorescent recognition of ...

Systolic pressure at ankle level was measured at the Arteria tibialis posterior and the Arteria dorsalis pedis. Two individual series of measurements of arterial pressures per subject across the assessed visits were selected for the analysis. For the first analysis (worst change analysis) the series of measurements in the one artery which has the worst change from Baseline at the final measurement was used. For the second analysis (worst value analysis) the series of measurements which has the worst final post-Baseline measurement was used. The series relevant for the analyses was selected from the series for the affected leg or legs only. The selection is 1 out of up to 4 series available per subject. Series without Baseline value and series with at least 1 measurement of more than 150 mmHg were excluded from the selection process due to the suspicion of media sclerosis of the lower limb artery ...
The prevalence of PAOD in patients with CAD ranges from 5 to 40% (5,10,21-26). Such broad range may be justified by the fact that prevalence studies enroll different populations, are not randomized, investigate few clinical presentations of coronary disease, and use different diagnostic methods. Most studies that used ABPI enrolled small samples, sometimes only hospitalized patients who probably had more severe CAD. Therefore, comparisons with results of studies that selected large and diversified samples of patients with CAD are difficult (10,19). The measurement of ABPI is a widely accepted method for epidemiological studies (13,14). However, results vary according to the time when patients are examined and who performs the measurements (27). This index also shows a greater number of false-negative results among patients with diabetes because of the calcification of artery walls. It is estimated that 5 to 10% of patients with diabetes have an artificial elevation of blood pressure due to the ...

Of the approximately 8 million Americans who suffer from ischemic peripheral arterial occlusive disease (PAOD), many present with intermittent claudication, or pain associated with exercise. Impaired vasodilation of resistance vessels is a potential explanation for this symptom. Occluded arteries can lead to increased flow through collateral vessels, which function as natural bypasses around the obstruction. This increase in blood flow and resulting shear stress can cause outward remodeling, or arteriogenesis, which improves the efficacy of collaterals. However, following femoral artery ligation in a mouse model of chronic ischemia, vasodilation in the stem region of collateral vessels is impaired at day 7. In the outwardly remodeled collateral stem, the vessel diameter increase is not associated with cell proliferation, suggesting the functionality of the present smooth muscle cells (SMCs) may account for the impaired vasodilation. A potential mechanism for increased vessel diameter in the collateral

BACKGROUND: Peripheral arterial occlusive disease (PAOD) is a common cause of morbidity and mortality due to cardiovascular disease in the general population. Although numerous treatments have been adopted for patients at different disease stages, no option other than amputation is available for patients presenting with critical limb ischaemia (CLI) unsuitable for rescue or reconstructive intervention. In this regard, prostanoids have been proposed as a therapeutic alternative, with the aim of increasing blood supply to the limb with occluded arteries through their vasodilatory, antithrombotic, and anti-inflammatory effects. This is an update of a review first published in 2010. OBJECTIVES: To determine the effectiveness and safety of prostanoids in patients with CLI unsuitable for rescue or reconstructive intervention. SEARCH METHODS: For this update, the Cochrane Vascular Information Specialist searched the Specialised Register (January 2017) and the Cochrane Central Register of Controlled ...

Hypertension (HT) is the leading preventable cause of premature death worldwide, and about every third person suffers from hypertension (1). In the long run, high blood pressure damages important organs such as the heart, blood vessels, the brain and the kidneys. Consequential diseases such as myocardial infarction, stroke, peripheral arterial occlusive disease, retinal damage or kidney damage result from the damaged vessels caused by high blood pressure.. Inflammation is a hallmark of hypertension, and there is a mounting evidence suggesting that chronic low-grade inflammation contributes to cardiovascular disease (CVD) including HT (2-5). Endothelial dysfunction, oxidative stress, cytokines, toll-like receptors, inflammasomes, and gut microbiome interact in a complex and intricate way (6). Reducing inflammation therefore contributes to successful prevention and management of hypertension. Systemic inflammation can also be triggered by food. Proteins or protein-derived compounds that occur in ...

Among high risk patients with known occlusive arterial disease and a greater than 3% annual risk of a vascular event (defined as non-fatal myocardial infarction, non-fatal stroke, or vascular death), the benefits of aspirin substantially outweigh the risks of bleeding. A recent meta-analysis of randomised trials of antiplatelet drugs versus control showed that for every 1000 such patients treated for a year, aspirin would be expected to prevent about 10-20 vascular events and cause one or two major gastrointestinal bleeds.1 In a wide range of high risk … ...

A method of surgically treating occlusive disease in an intraluminal tissue using both a retractor (6) and a retractable one-piece stent. The stent is constructed and arranged such that it can exist in at least a stable initial collapsed state (12) and a stable deployed expanded state (10). In conjunction with the retractor, the stent is positioned at an appropriate location within an occluded intraluminal tissue and converted from a stable initial collapsed state to a stable deployed expanded state, and is then converted to a collapsed state and removed before significant restenosis occurs.
LCX artery occlusions are estimated to account for 20% of MIs.5,6 They may pose a diagnostic dilemma, primarily if the ECG findings are non-diagnostic for STEMI. Subsequently, these patients are more likely to undergo PCI more than 24 hours from onset of symptoms compared to patients with more readily recognizable left anterior descending (LAD) and right coronary artery (RCA) occlusions.5 LCX lesions are associated with increased risk of heart failure and mortality at 90 days and 1 year compared to RCA and LAD lesions.7 In addition, there have been multiple reports indicating higher peak levels of cardiac biomarkers, suggesting larger infarct sizes and thus more myocardial necrosis.8. Attempts at improving early diagnosis of total occlusion lesions in the LCX have had limited success. According to one study, angiography-proven LCX total artery occlusions only met STEMI criteria 46% of the time, and the addition of posterior leads (V7-V9) only improved sensitivity 6-14% of the time.9 Isolated V2 ...
Various peripheral arterial occlusive lesions have traditionally been managed with surgical therapy. However, endoluminal intervention with catheter-based techniques has become quite common and, in many cases, is now the treatment of choice.
A PubMed search was conducted with the question to evaluate the evidence on the optimal reference standard for radiological sequencing to investigate and confirm a clinical diagnosis of PAES. The search terms included were "popliteal artery entrapment syndrome" or "PAES" and "radiology" and "imaging". The included articles were published from 2014 onward full text availability was a requirement. The search criteria excluded review articles (n=2), articles pertaining to surgical treatment (n=1), articles pertaining to surgical procedural factors (n=1), prostatic artery embolisation (n=2) and chronic galactocele (n=1). Subsequently, four articles were included in this review. The criteria yielded two case studies, a peer-reviewed editorial and a retrospective case series..

Endovascular treatment is an established modality of femoropopliteal occlusive disease. However, there are conflicting results concerning the choice of applying percutaneous transluminal angioplasty (PTA) or stenting (ST). Aim of this study, is the systematic review of the most recent studies in the international references where the results of the two methods are compared, in order to determine, using standard evidence based criteria, the safety and effectiveness of the two methods. Screening of the database Medline/PubMed and Cochrane, covering the period between January 1999 to December 2010 with additional literature search of the references of the articles was done in order to discover the studies that deal with the subject of this systematic review. The investigation was limited in meta-analysis and either randomized or not controlled trials. The critical evaluation of the studies was performed according to the Impact factor of the Journal on which they were published. Sixteen studies were ...

Peripheral Arterial Occlusive Disease (PAOD) is an acquired inflammatory disease where a peripheral artery becomes occluded due to the buildup of atherosclerotic plaques. In patients that possess collateral arteries, an occlusion can lead to shear induced outward remodeling, arteriogenesis, of these collaterals, partially restoring blood flow. However, newly remodeled collaterals exhibit reduced functional vasodilation, which may impair normal activity, such as ambulation. To model chronic ischemia and arteriogenesis in collaterals, a femoral artery ligation in a murine hindlimb is commonly performed. Previous efforts by our group involved measurements of collateral artery diameter to assess the impact of arteriogenesis on functional vasodilation/vascular reactivity; however diameter measurements are not as descriptive as an assessment of flow, and performing particle image velocimetry allows the change in blood flow control to be investigated. Particle image velocimetry was performed in the profunda
In patients with peripheral arterial disease, obstructing plaques caused by atherosclerotic occlusive disease commonly occur in the infrarenal aorta and iliac arteries. Atherosclerotic plaques may induce symptoms either by obstructing blood flow or by breaking apart and embolizing atherosclerotic and/or thrombotic debris to more distal blood ...

It is well recognised that vascular tissue and mechanisms of cervical arterial dysfunction (CAD) may give rise to pain in the cranio-cervical region (Taylor and Kerry 2005). It is perhaps less well known that vascular tissue can be the source of pain syndromes throughout the body, ranging from the obvious - abdominal aortic aneurysm (low back pain), through to the less obvious (or less well known) distal limb pain/numbness as a result of popliteal artery entrapment syndrome (PAES). PAIN may be local due to a nociceptor response in the tunica adventitia due to underlying pathology (arterial dissection, atherosclerosis, aneurysm) or distal due to ischaemia (which may be movement or exercise induced ...

Fig. 2. Differences in collateral growth and tissue recovery in animal models versus humans with arterial occlusive disease. (A) After an acute arterial ligation (shown here in a mouse), there is a strong pressure gradient between the proximal and distal sides of the occlusion (orange line). This redirects the blood flow into adjacent arterioles and causes a strong shear-stress-mediated opening of collateral channels, which restore blood flow into the hypoxic areas. In the hypoxic tissues, ischemic tissue damage (necrosis) occur if the blood flow is not restored within the first hours after the occlusion. Necrosis induces acute inflammation, and recruited inflammatory cells produce angiogenic cytokines such as VEGF. The hypoxia itself activates factors such as HIF that stimulate the production of VEGF among other factors, and angiogenesis. Distal angiogenesis, along with the growth of collaterals, contributes to the tissue recovery by the formation of connections between the collaterals and the ...
The possibility that variation in the extent of native collateral circulation is an important determinant of variation in ischemic injury when acute arterial occlusion occurs or disease becomes manifest has historically been overlooked or minimized-, with the exception of those who study or treat acute ischemic stroke7-14 (and references therein), some coronary investigators4-6,69 (and references therein), and among vascular surgeons who frequently encounter or perform arterial occlusions.70,71 This presumably extends, in part, from the small diameter typical of native collaterals in most healthy individuals that is beyond the resolution of digital angiography (,0.2 mm), from the misconception that such minute vessels cannot mediate significant flow in the acute setting until remodeling has occurred, and from the inability to experimentally change native collateral extent to test its importance. The latter restriction has begun to yield in recent studies in which collateral extent was found to ...
