OBJECTIVES: One third of infrainguinal vein bypasses may fail within the first 1.5 years. Pro- and anti-inflammatory mechanisms are thought to be involved in these graft stenoses and occlusions. In previous studies, low levels of anti-phosphorylcholine IgM (anti-PC IgM, an innate anti-inflammatory IgM) have been associated with increased cardiovascular events. In this study, the peri-operative dynamics of anti-PC IgM levels were established during leg bypass surgery, and associations assessed between anti-PC IgM levels and primary graft patency...

BACKGROUND: The radial approach to cardiac procedures has become increasingly common. While previous studies have suggested a favorable risk profile, serious complications can occur. The purpose of this study was to examine the incidence, subsequent treatment and outcome of all suspected significant neurovascular complications following trans-radial cardiac procedures at a large US hospital. METHODS: We reviewed all patients who underwent a left heart catheterization, coronary angiogram, or percutaneous coronary intervention via the trans-radial approach at a single large academic medical center in the United States between 2010 and 2016...

BACKGROUND: The prevalence of peripheral arterial disease (PAD) in Australia is currently poorly characterized. The risk factor profile for PAD is changing with the population ageing, diabetes increasing and smoking rates declining. The management of PAD is also evolving, with advances in medical management and endovascular technique. The trends in PAD prevalence and surgical management have implications for preventative medicine, the Australian health system and vascular surgery. We report and analyse trends in PAD surgical intervention performed between 2001 and 2015...

Prevalence of atherosclerotic peripheral artery disease (PAD) has steadily been increasing all over the world, affecting approximately 10% of the population. PAD dramatically decreases the patients' quality of life and is accompanied by high risks of limb amputation and death. Reconstructive and restorative interventions make it possible to achieve the highest success in treatment of PAD. Their results largely depend on the state of the patient's peripheral bed. Currently, the periphery is objectively assessed by means of ultrasonographic duplex examination, digital subtraction angiography, roentgen computed tomographic angiography (CTA), and in a series of cases magnetic resonance tomographic angiography (MRA)...

As the population of older individuals grows worldwide, researchers have increasingly focused their attention on identifying key molecular targets of age-related cognitive impairments, with the aim of developing possible therapeutic interventions. Two such molecules are the intracellular cyclic nucleotides, cAMP and cGMP. These second messengers mediate fundamental aspects of brain function relevant to memory, learning, and cognitive function. Consequently, phosphodiesterases (PDEs), which hydrolyze cAMP and cGMP, are promising targets for the development of cognition-enhancing drugs...

The first reported human anaphylactic death is considered to be the Pharaoh Menes death, caused by a wasp sting. Currently, anaphylactic cardiovascular events represent one of most frequent medical emergencies. Rapid diagnosis, prompt and appropriate treatment can be life saving. The main concept beyond anaphylaxis lies to myocardial damage and ventricular dysfunction, thus resulting in cardiovascular collapse. Cardiac output depression due to coronary hypoperfusion from systemic vasodilation, leakage of plasma and volume loss due to increased vascular permeability, as well as reduced venous return, are regarded as the main causes of cardiovascular collapse...

Objectives To date, the ultimate decision to treat iliac artery stenoses in patients suffering from symptomatic peripheral arterial disease is based on the patient's symptoms and on visual inspection of angiographical images. The primary aim of this study was to investigate the accuracy of geometry-based methods (i.e. visual inspection and quantitative vascular analysis (Viewforum version R7.2v1 Advanced vessel analysis, Philips Healthcare, Best, The Netherlands) of 3D rotational angiography) to identify the severity of equivocal iliac artery stenosis in peripheral arterial disease patients with intra-arterial hyperemic pressure measurements (gold standard) as a reference...

OBJECTIVE: Contrast-induced nephropathy (CIN) is a frequently used quality outcome marker after peripheral vascular interventions (PVIs). Whereas the factors associated with CIN development have been well documented, the long-term renal effects of CIN after PVI are unknown. This study was undertaken to investigate the long-term (1-year) renal consequences of CIN after PVI and to identify factors associated with renal function deterioration at 1-year follow-up. METHODS: From 2008 to 2015, patients who had PVI at our institution (who were part of a statewide Vascular Interventions Collaborative) were queried for those who developed CIN...

BACKGROUND: The burden of metabolic syndrome (MetS) is increasing in the United States and is pervasive among patients with peripheral arterial disease. Whereas MetS has been implicated in the development of all types of cardiovascular disease and adverse outcomes after vascular interventions, little is known about how MetS influences perioperative outcomes of lower extremity bypass surgery and whether any negative effects can be modified by use of cardiovascular risk-modifying medications...

The updated ESC guidelines on PAD were developed, for the first time, as a collaboration between cardiologists and vascular surgeons and unveiled at the European Society of Cardiology (ESC) 2017 congress. Although awareness has improved, PAD is still associated with significant morbidity, mortality, and quality of life impairment. Primarily, the guidelines emphasize the need for a multidisciplinary management of these patients and propose "a vascular team". A new chapter on antithrombotic therapies is provided...

AIM: To examine associations between diabetic retinopathy (DR) and common micro- and macrovascular complications of diabetes mellitus, and how these could potentially impact clinical practice. MATERIALS AND METHODS: A structured search of the PubMed database identified studies of patients with diabetes that assessed the presence or development of DR in conjunction with other vascular complications of diabetes. RESULTS: From 70 included studies, we found that DR is consistently associated with other complications of diabetes, with the severity of DR linked to a higher risk of the presence of, or developing, other micro- and macrovascular complications...

An 84-year-old woman was admitted to our hospital because of congestive heart failure, rapid atrial fibrillation, and ischemic heart disease. Percutaneous coronary intervention (PCI) via the left radial artery was performed, and a stent was deployed successfully into left anterior descending coronary artery (LAD). She got into shock state one hour after PCI. Chest X-ray and computed tomography scan revealed increase of soft tissue around the left axilla and implied the existence of hematoma. Hemoglobin level decreased from 13...

BACKGROUND: The resting ankle-brachial index (ABI) is a clinical test to diagnose peripheral artery disease (PAD). The Wyatt's score has been proposed to assess the students' performance on ABI measurement on a healthy volunteer (HV). No study has shown that this score is sensitive to different teaching methods. In this randomized-controlled-trial, we wanted to determine whether didactic learning alone or didactic learning combined with experiential learning improve proficiency in the ABI procedure assessed by the Wyatt's score...

The impact of dual antiplatelet therapy (DAPT) cessation after percutaneous coronary intervention with drug eluting stent implantation in patients at high atherothrombotic risk remains unclear. We aimed to characterize the risk for adverse events, and its relationwith the mode of DAPT cessation in patients at high atherothrombotic risk (HATR). Considering patients treated with drug-eluting stents among those enrolled in the Patterns of Non-Adherence to Anti-Platelet Regimens in Stented Patients registry, wedefined subjects with prior myocardial infarction (MI), prior stroke or peripheral vascular disease at HATR, while patients without any of these conditions were classified as atherothrombotic risk (LATR)...

INTRODUCTION: Routine noninvasive vascular study results can be affected by a multitude of factors and do not provide information specific to the location of the wound. Results must be extrapolated and may prompt a false sense of security that adequate perfusion for healing exists. CASE REPORT: The case of an 80-year-old Caucasian man, who presented with chronic ulceration of the left lateral malleolus and fifth metatarsal base with concurrent metatarsal osteomyelitis, is presented...

BACKGROUND: Despite suggestions that severe left ventricle dysfunction may warrant selection of durable mechanical circulatory support over conventional surgery, comparative studies are lacking due to incomplete characterization of patients at highest risk after conventional surgery. We sought to define subsets of patients with severe left ventricle dysfunction who are at greatest mortality risk following conventional cardiac surgery. METHODS: We studied 892 patients aged ≥ 18 years who underwent conventional coronary or valve surgery from 1993 to 2014, with preoperative ejection fraction ≤ 25%...

OBJECTIVE: Extracorporeal membrane oxygenation (ECMO) is an important life-saving modality for patients with cardiopulmonary failure. Vascular complications, including clinically significant limb ischemia, may occur as a result of femoral artery cannulation for venoarterial (VA) ECMO. This study examines our institutional experience with femoral VA ECMO and the development of ipsilateral limb ischemia. METHODS: We performed a retrospective review of all consecutive patients undergoing femoral VA ECMO between 2011 and 2016...
