Correlation between preoperative vein and artery diameters and arteriovenous fistula outcome in patients with end-stage renal disease.

Background And Aims: Arteriovenous fistula (AVF) maturation failure rates remain high in patients with end-stage renal disease (ESRD). Although preoperative morphological and functional assessment of blood vessels by duplex ultrasonography (DUS) has been shown to improve AVF maturation, there is no consensus regarding the optimal vein (VD) and artery (AD) diameters to be universally used for AVF creation. To improve patient selection, set out to investigate if there is a correlation between preoperative VD/AD and clinical covariates, and postoperative AVF outcome.

Ghrelin and acyl ghrelin levels are associated with inflammatory and nutritional markers and with cardiac and vascular dysfunction parameters in hemodialysis patients.

Purpose: Exogenous ghrelin is associated with cardiovascular protection in experimental and human studies. Nevertheless ESRD patients have increased ghrelin levels and severe cardiovascular comorbidities. This study aims to elucidate the metabolic factors influencing endogenous ghrelin/acyl ghrelin levels and to analyze the relation between endogenous ghrelin/acyl ghrelin levels and cardiac and vascular function markers in hemodialysis patients.

Effect of the veins histopathological characteristics and preexisting medical conditions on arteriovenous fistula maturation and primary patency in patients with end-stage renal disease: an observational, prospective study.

We assessed the veins histopathological characteristics and preexisting medical conditions before arteriovenous fistula (AVF) creation, and their correlation with AVF outcome and primary patency in patients with end-stage renal disease (ESRD). In this observational, prospective, mono-center study in Romania, patients with artery and venous diameters =2 mm and =2.5 mm, respectively, were enrolled.

Matrix-Metalloproteinase-2 Predicts Arteriovenous Fistula Failure in Hemodialysis Patients.

In hemodialysis patients the principal cause of arteriovenous fistula dysfunction is stenosis. Matrix-metalloproteinase-2 is implicated in the pathophysiological mechanism of stenosis development. Our study tried to assess the clinical impact of this protease on arteriovenous fistula survival.
