With the advance of radial access and ulnar access there has been an increased interest in performing right heart catheterization (RHC) and right-heart based procedures via antecubital venous access. Our purpose is to describe the venous anatomy of the upper extremities, technique, equipment, and cost for employing this approach. Reported also is the international experience based on publications assessing procedural success, complications, fluoroscopy time and radiation dose, access-site compression time, and time to ambulation...

Cardiac catheterization has greatly contributed to the progress made in the management of congenital heart diseases (CHD). Initially used in diagnosis, it allowed the understanding of heart diseases, their anatomy and hemodynamics. Gradually, the development of interventional cardiology has played a major role in the management of these malformations (Patent ductus arteriosus [PDA] and atrial septal defect [ASD] closure, pulmonary dilatation, percutaneous pulmonary valve implantation…). The development of such technology was made possible through the concomitant development of imaging techniques: fluoroscopy, ultrasound, MRI and CT...

Therapeutic hypothermia has been shown to improve neurologic outcome in medical cardiac arrest patients, yet little is known about factors that delay target temperature achievement. Our primary aim was to identify factors associated with not achieving our institutional "door-to-cool" (DTC) performance goal (emergency department [ED] arrival to temperature of 34°C) of ≤4 hours. Secondary aims included whether achievement of DTC goal was associated with timing of bolus neuromuscular blockade (NMB), survival, or functional outcome...

INTRODUCTION: The likelihood of detecting vesicoureteral reflux (VUR) after febrile urinary tract infections (UTI) in children logically should correlate with the correct diagnosis of the UTI. Beneath the unspecific symptoms of fever urine analysis is the main diagnostic criterion for the exact diagnosis of febrile UTIs in children. Use of inadequate urine sampling techniques during diagnosis may lead to impaired accuracy in UTI diagnosis. This could lead to the assumption that children, having diagnosed their UTI by the use of possibly inadequate urine sampling techniques should not be evaluated as consequently compared to those, where the diagnosis relied on sterile urine sampling techniques...

The use of central venous catheters (CVC) is associated with a risk of microbial colonization and subsequent potentially severe infection. Microbial contamination of the catheter leads to the development of a microbial consortia associated with the CVC surface and embedded in an extracellular matrix, named biofilm. This biofilm provides bacterial cells the ability to survive antimicrobial agents and the host immune system and to disseminate to other sites of the body. The best preventive strategy is to avoid any unnecessary catheterization or to reduce indwelling duration when a CVC is required...

This study aims to explore the effect of intravenous anesthesia on the adrenal gland functions of rats with sepsis as well as on their lungs and adrenal gland tissues in order to provide a theoretical reference for the cure of sepsis. Female Sprague Dawley (SD) rats were taken as the research objects in this study. Venous channels of rats were constructed by catheterization through the external jugular vein, and the cecal ligation and puncture technique was adopted to duplicate the sepsis rat models. The level of tumor necrosis factor-α (TNF-α) in serum was detected using enzyme-linked immunosorbent assay (ELISA), and necrocytosis was observed by the fluorescent staining method...

Patients with advanced cirrhosis often present a hyperdynamic circulation characterized by a decrease in systolic and diastolic blood pressure (SBP and DBP), and an increase in heart rate (HR) and cardiac output (CO). Accurate assessment of the altered circulation can be performed invasively; however, due to the disadvantages of this approach, non-invasive methods are warranted. The purpose of this study was to compare continuous non-invasive measurements of haemodynamic variables by the Finometer and the Task Force Monitor with simultaneous invasive measurements...

Pulmonary arteriovenous malformation (AVM) is not routinely appreciated during the standard echocardiogram to assess for structural abnormalities or pulmonary hypertension. The distal pulmonary AVM is suspected only if an injection of agitated saline is performed and late entry of particles is appreciated in the left heart structures. A large or complex pulmonary AVM can result in significant right-to-left shunting and consequential systemic hypoxemia in the presence or absence of pulmonary hypertension. For direct visualization of the pulmonary AVM, computerized tomography (CT) scan is the procedure of choice...

Transarterial chemoembolization (TACE) is considered a standard local-regional treatment for intermediate-stage hepatocellular carcinoma (HCC) and the most common bridging therapy. This treatment is offered to more than 70% of patients who are on the waiting list for liver transplantation in the United States. HCC typically receives its blood supply from the hepatic artery; however, it can recruit a parasitic supply from extrahepatic collateral (EHC) arteries. The development of an EHC arterial blood supply can interfere with the therapeutic efficacy of TACE and result in treatment failure and poor outcome...

Fenestrated endovascular aneurysm repair (FEVAR) is an alternative to open repair of complex aortic aneurysms. Despite promising short-term results, the technical complexities of this procedure remain a considerable challenge. The risk of technical failure with loss of visceral or renal arteries is ubiquitous even in the most experienced hands, and thus many patients with unfavorable anatomy are frequently denied FEVAR. We have adopted a new technique for FEVAR that involves retrograde brachial artery access and stepwise deployment of the endograft during target vessel catheterization, overcoming many anatomic limitations encountered from a transfemoral approach...

A 2-year-old, 3.8-kg male Rhode Island red rooster was examined for lameness and progressive swelling of the right foot of several month's duration. Radiographs of the right foot demonstrated soft tissue swelling and a smoothly marginated periosteal reaction evident of inflammation affecting the bones. Results of a complete blood count showed a moderate leukocytosis and an elevated total protein concentration. Systemic antibiotic and anti-inflammatory therapy was started, but the bird had not improved at recheck examination...
