Background and Objectives: Arteriovenous fistula is a popular vascular access method for surgical treatment of hemodialysis patients. The method, however, is associated with a high rate of early failure varying in the range of 20-60%. Predicting early Arteriovenous fistula failure and its risk factors can help reduce its incidence, its hospitalization rate, and associated costs. In this study, ...

conclusions we think one of the influential factors for leading a guidewire and catheter into a nominated vein may be the left sided bevel of the needle at the time of internal jugular vein needle and catheter insertion. we were required to continue going towards the subclavian vein and accidentally turned into the left internal mammary vein. introduction central venous catheter placement is a ...

Central venous catheters in nephrology were originally introduced to provide temporary vascular access for shortterm dialysis and were never meant to play a part in the dialysis patients’ long term care. Currently, tunneled, cuffed, doublelumen silastic catheters are used for permanent vascular access in many patients, particularly those with limited alternative options for vascular access and ...

a bstra ct   background: vascular access complications are a major cause of excessive morbidity and mortality in the dialysis population. moreover, there is not sufficient research regarding the factors correlated with vascular access complications among hemodialysis patients. this study aimed to evaluate the vascular access complications and their related factors such as nursing techniques and...

We report two cases in which patients on chronic hemodialysis presented with morbid unilateral edema of the upper extremity and chest on the side of a currently functioning arteriovenous access. Both patients were known to the vascular surgery service and had previously undergone multiple attempts to create and maintain vascular access. Both severe and disabling edema and the need to maintain d...

PURPOSE Preservation of adequate vascular access is of vital importance for patients undergoing chronic dialysis in renal failure. The aim of this study is to evaluate the successful access rate and risk factors of arteriovenous fistula (AVF) in the arm for dialysis at a single center. MATERIALS AND METHODS Patients undergoing vascular access operation between January 2006 and December 2011 w...

Trying to use embryonic stem cells about 20 years ago, working with animals,  especially rats began. During these years , many experiments in mouse embryonic stem cells to transform into a variety of cells and transplanting them were led to remarkable success . In the next issue of human stem cells were considered successful until finally in 1998 the first report was published in the proliferat...
