BACKGROUND: Contrast induced nephropathy (CIN) may be defined as Acute Renal Failure (ARF) that occurs within 24-72h of exposure to intra-venous or intra-arterial iodinated contrast media that cannot be attributed to other causes. CIN occurs in up to 5% of hospitalized patients with normal renal function prior to injection of contrast media. It occurs more frequently in patients with renal impairment particularly if associated with diabetic nephropathy. Among all procedures utilizing contrast agents for either diagnostic or therapeutic purposes, coronary angiography and percutaneous coronary interventions are associated with the highest rates of CIN...

BACKGROUND: Erosive pustular dermatosis of the leg (EPDL) is a poorly understood entity first described by Lanigan and Cotteril in 1987. Its clinical diagnosis is based on exclusion since the physiopathology is unknown. The primary objective of this investigation was to specify the clinical aspects and outcomes in a prospective study. The secondary objectives were to describe associated diseases, the circumstances of occurrence, and the laboratory tests used. PATIENTS AND METHODS: This was a prospective study that included 45 patients selected by members of the Angiology-Dermatology Group of the SFD (French Dermatology Society) at 13 centres between 01/09/2013 and 31/10/2014...

Chronic venous disease is a common disorder associated with a variety of symptoms in later disease stages but also with complications such as venous leg ulcer. This, in turn, has substantial socioeconomic effects and significantly impacts patients' quality of life. While there are a number of diagnostic procedures available, color-flow duplex ultrasound has become the gold standard. As regards therapeutic options, major advances have been made in recent decades. Today, there are alternatives to saphenofemoral ligation and stripping of the great saphenous vein, including endovenous thermal ablation techniques...

Patients born with a single functional ventricle typically undergo three-staged surgical palliation in the first years of life, with the last stage realizing a cross-like total cavopulmonary connection (TCPC) of superior and inferior vena cavas (SVC and IVC) with both left and right pulmonary arteries, allowing all deoxygenated blood to flow passively back to the lungs (Fontan circulation). Even though within the past decades more patients survive into adulthood, the connection comes at the prize of deficiencies such as chronic systemic venous hypertension and low cardiac output, which ultimately may lead to Fontan failure...

Mesenteric vascular insufficiency is a serious medical condition that may lead to bowel infarction, morbidity, and mortality that may approach 50%. Recommended therapy for acute mesenteric ischemia includes aspiration embolectomy, transcatheter thrombolysis, and angioplasty with or without stenting for the treatment of underlying arterial stenosis. Nonocclusive mesenteric ischemia may respond to transarterial infusion of vasodilators such as nitroglycerin, papaverine, glucagon, and prostaglandin E1. Recommended therapy for chronic mesenteric ischemia includes angioplasty with or without stent placement and, if an endovascular approach is not possible, surgical bypass or endarterectomy...

A 79-year-old male chronic hemodialysis patient with no history of central venous catheterization was referred to our hospital with progressive swelling of the left upper limb ipsilateral to a forearm arteriovenous fistula. Radiological assessments revealed marked hyperostosis in the ribs, sternum, and clavicles with well-developed ossification of the sternocostoclavicular ligaments. Such characteristic structural abnormalities and our failure to identify the left subclavian vein with contrast material despite the abundant dilated collaterals in the left shoulder area encouraged us to diagnose our patient with sternocostoclavicular hyperostosis (SCCH) complicated by central vein obstruction...

BACKGROUND: Approximately 24% of adults in the United States have visible varicose veins, and an estimated 6% have evidence of advanced chronic venous disease. The majority of individuals with varicose veins seek treatment because of symptoms, such as aching, throbbing, fatigue, pruritus, ankle swelling, and tenderness, rather than cosmetic reasons. Furthermore, varicose veins are a manifestation of chronic venous insufficiency, which can progress to leg pain, leg edema, chronic skin changes, and nonhealing ulcers...

Chronic venous insufficiency is an often-missed diagnosis that results in a variety of clinical manifestations that may severely compromise quality of life. Prompt recognition is important to provide symptomatic relief and prevent disease progression. Most patients can be treated with a comprehensive plan of conservative measures. However, it is important for providers to recognize those patients who require referral to a vascular specialist for more invasive therapies. Over the past 2 decades, a variety of endovenous strategies have demonstrated effective and lasting results in treatment of severe symptomatic venous insufficiency...

<i>Chronic cerebrospinal venous insufficiency (CCSVI) is a series of stenotic malformations in the cerebrospinal venous outflow routes, which is postulated to cause multiple sclerosis (MS). The hypotheses assumed that CCSVI leads to iron deposition which triggers inflammation and demyelination in MS. Invasive endovascular treatment of CCSVI was initiated based on the previous theory. The present study was designed to validate this hypothesis using a rat model of CCSVI. Bilateral jugular vein ligation (JVL) was performed on female albino rats (n = 15), and sham-operated rats (n = 15) were used as a control group...

Nathan W Kugler, Kellie R Brown
BACKGROUND: Chronic venous insufficiency affects millions of Americans with symptoms spanning a broad range. Saphenous incompetence resulting in chronic reflux is at the root of most disease and is amenable to surgical correction. METHODS: We conducted a systematic review of the literature on nonthermal ablative techniques using a MEDLINE (Ovid) search from January 2000 to August 2016. Only prospective studies and literature review articles in the English language were included for final analysis...

OBJECTIVE: Although duplex ultrasound (DUS) imaging is the current gold standard in the diagnosis of femoropopliteal deep venous thrombosis, it is not an optimal diagnostic modality to diagnose iliocaval occlusion. Screening for iliocaval occlusion thus remains a challenge for clinicians because of the lack of a reliable noninvasive technique. This challenge results in most patients undergoing computed tomography venography or magnetic resonance venography or invasive venography and intravascular ultrasound imaging...

Background The development and use of minimally invasive procedures provide improved options for the management of symptoms of chronic venous insufficiency. While many patients with iliac venous occlusive disease and superficial venous insufficiency improve with combined iliac venous stenting and correction of superficial venous reflux, some patients have symptoms which persist. The goal of this study was to identify clinical factors related to persistent symptoms in patients with leg swelling after treatment of both iliac vein stenting and thermal ablation...

We investigated the impact of contrast media (CM) with different osmolality on cardiac preload in patients with chronic kidney disease (CKD) and congestive heart failure (CHF). Patients with CKD and CHF were equally randomized to receive either iso-osmolar contrast media (IOCM) iodixanol or low-osmolar contrast media iopromide. We measured cardiac preload indexes by invasive hemodynamic monitoring before and after CM injection. Major adverse cardiac events postprocedures were recorded. Increase in extravascular lung water index was only seen in the iopromide group ( P < ...

Objective Inflammation has been implicated as a factor that may contribute to chronic venous insufficiency. The purpose of this study is to compare readily available inflammatory cell biomarkers, with an emphasis on neutrophil count, lymphocyte count, and neutrophil lymphocyte ratio, in patients with chronic venous insufficiency. We hypothesized that circulating leukocyte counts would be higher in the peripheral blood of patients with severe compared to mild chronic venous insufficiency. Methods We performed a retrospective medical record review of patients discharged from Ruby Memorial Hospital (Morgantown, WV, USA) with a primary diagnosis of chronic venous insufficiency...

BACKGROUND: Chronic venous insufficiency is a frequently occurring disease consisting of a characteristic symptom complex and ulcerations. Normally, varicose veins with reflux or obstruction can be found. However, these symptoms have also been described in obese people and are considered functional chronic venous insufficiency. The aim of this work was to present patients with ulceration in obesity-associated chronic venous insufficiency and to describe typical features of ulceration in obese people...
