1. Acessos arteriovenosos de alto débito estão associados a pior hemodiálise?
RESUMO Introdução: Um débito de sangue de acesso arteriovenoso (AV) (Qa) de 400 mL/min é geralmente suficiente para uma hemodiálise (HD) eficaz, mas alguns acessos continuam se desenvolvendo e se tornam acessos de alto débito (AAD). Alguns autores postularam que um AAD poderia desviar uma porção significativa do sangue dialisado do débito cardíaco

2. Risks and benefits of the intercostal approach for percutaneous nephrolithotripsy
OBJECTIVE:The objective of our retrospective study was to provide evidence on the efficacy of the intercostal versus subcostal access route for percutaneous nephrolithotripsy. MATERIAL AND METHODS: 642 patients underwent nephrolithotomy or nephrolithotripsy from 1996 to 2005. A total of 127 had an intercostal access tract (11th or 12th); 515 had a subcostal

3. Vascular access-related infections in HIV patients undergoing hemodialysis: case description and literature review
Poor immune status, the use of a vascular access different from an AV fistula, and intravenous drug use (IDU) may favor increased rates of vascular access infections among HIV infected patients on hemodialysis. Staphylococcus spp. and Streptococcus spp. are the main cause of these infections, but Gram-negative rods and fungi have been found as well. Using an

4. Síndrome de Foix-Alajouanine: relato de caso
Em mulher de 52 anos, malformação artério-venosa medular (MAV) associava-se com a síndrome de Foix-Alajouanine. A fisiopatologia da fístula artéria-venosa provavelmente está relacionada com a pressão venosa aumentada, a partir da MAV associada com o processo trombótico. Os sintomas iniciais mais comuns são distúrbio sensorial, dor e fraqueza do me

5. Maximizing the natriuretic effect of endogenous atriopeptin in a rat model of heart failure.
The effect of pharmacological manipulation of atriopeptin (AP) activity on sodium excretion and blood pressure was examined in the rat aortovenocaval (A-V) fistula model of cardiac failure. Introduction of an A-V shunt led to a marked and sustained elevation of plasma AP immunoreactivity and urinary cGMP levels. Further elevation of plasma AP levels by infus

6. TRAUMATIC ARTERIOVENOUS COMMUNICATION PRESENTING 36 YEARS AFTER INITIAL INJURY
A 59-year-old man who had sustained multiple pelvic fractures 36 years ago recently developed progressive neurological deficits. His symptoms suggested an arteriovenous (AV) malformation of the spinal cord. This report details the steps taken in locating the fistula angiographically and in performing a preliminary temporary obliteration using an intra-arteri

7. Cellular phenotypes in human stenotic lesions from haemodialysis vascular access
Background. Haemodialysis vascular access dysfunction (due to venous stenosis and thrombosis) is a leading cause of hospitalization and morbidity. The aim of the current study was to identify the specific cell types present within stenotic tissue samples from patients with AV fistula and graft failure.

8. CKD Accelerates Development of Neointimal Hyperplasia in Arteriovenous Fistulas
Arteriovenous (AV) access failure resulting from venous neointimal hyperplasia is a major cause of morbidity in patients with ESRD. To understand the role of chronic kidney disease (CKD) in the development of neointimal hyperplasia, we created AV fistulae (common carotid artery to jugular vein in an end-to-side anastomosis) in mice with or without CKD (renal

9. TNF-α inhibition attenuates adverse myocardial remodeling in a rat model of volume overload
Tumor necrosis factor (TNF)-α is a proinflammatory cytokine that has been implicated in the pathogenesis of heart failure. In contrast, we have recently shown that myocardial levels of TNF-α are acutely elevated in the aortocaval (AV) fistula model of heart failure. Based on these observations, we hypothesized that progression of adverse myocardial remodel
