BACKGROUND: Several studies have suggested that urgent-start peritoneal dialysis (PD) is a feasible alternative to hemodialysis (HD) in patients with end-stage renal disease (ESRD), but the impact of the dialysis modality on outcome, especially on short-term complications, in urgent-start dialysis has not been directly evaluated. The aim of the current study was to compare the complications and outcomes of PD and HD in urgent-start dialysis ESRD patients. METHODS: In this retrospective study, ESRD patients who initiated dialysis urgently without a pre-established functional vascular access or PD catheter at a single center from January 2013 to December 2014 were included...

INTRODUCTION: A radiocephalic arteriovenous fistula (AVF) is the best choice for achieving vascular access (VA) for hemodialysis, but this AVF has high rates of early failure due to juxta-anastomotic stenosis, making it impossible to use for dialysis. Low hemodynamic shear stress contributes to the pathophysiology of VA failure due to secondary thrombosis, stenosis, and re-occlusion after percutaneous intervention. METHODS: We used a computational fluid dynamics (CFDs) approach to evaluate the shear stress distribution and minimize its effects under various conditions including changes in the anastomosis angle...

Vascular access intervention therapy (VAIVT) has been positioned as the first choice of treatment for stenosis lesions frequently observed in arteriovenous fistula (AVF) for hemodialysis patients in Japan. Furthermore, increased blood flow can provide a stable dialysis. In contrast, it has been reported that excess blood flow of AVF causes high-output heart failure. Although VAIVT is used to increase blood flow of AVF, the impact of VAIVT on cardiac load has been rarely reported. We examined the factors associated with cardiac load in hemodialysis patients undergoing VAIVT by measuring levels of α human atrial natriuretic polypeptide (hANP) and brain natriuretic peptide (BNP) before and after VAIVT...

BACKGROUND: Vascular access (VA) is essential for hemodialysis (HD) patients, and its dysfunction is a major complication. However, little is known about outcomes in patients with recurrent VA dysfunction. We explored the influence of recurrent VA dysfunction on cardiovascular (CV) events, death and VA abandonment. METHODS: This is a single-center, retrospective study conducted in patients who underwent VA surgery between 2009 and 2014. VA dysfunction was defined as VA stenosis or thrombosis requiring intervention after the first successful cannulation...

BACKGROUND: The decision about the type and location of a hemodialysis vascular access is challenging and can be affected by multiple factors. We explored the effect of several a priori chosen patient characteristics on access outcomes. METHODS: We searched MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus through November 13, 2014. We included studies that evaluated patency, mortality, access infection, and maturation of vascular access in adults requiring long-term dialysis...

BACKGROUND & OBJECTIVES: Access monitoring and pre-emptive angioplasty is known to decrease the incidence of AVF/AVG thrombosis. The effect on increase the longevity and functionality of Arterial-Venous access (AV access) in end-stage renal disease (ESRD) patients is not settled. Thrombosis is the leading cause of vascular access complications and is almost always associated with the presence of stenosis. Percutaneous transluminal angioplasty (PTA) is an accepted treatment of stenotic lesions in AV access (NKF 2001)...

BACKGROUND: Vascular access has always been the Achilles heel of hemodialysis. Advances in health care have brought forward patients requiring treatment who have no veins suitable for creation of arteriovenous fistula (AVF) or insertion of central venous catheters. Use of an artery as permanent vascular access has been reported by many authors. This study reports brachial AAPL as an efficient and safe access for hemodialysis patients with central venous occlusion. METHODS: Between January 2011 and December 2014, 35 brachial arterio-arterial prosthetic loops (AAPL) were created...

BACKGROUND: Use of the forearm basilic vein for the creation of an arteriovenous fistula has been codified as second-choice vascular access for hemodialysis in the last clinical guidelines of the Society for Vascular Surgery in 2008. Poor literature data on this technical option and on its evaluation and outcomes led us to initiate a retrospective single-center study. METHODS: We analyzed the outcomes of every arteriovenous fistula using the forearm basilic vein created in our department...

Chronic hemodialysis is implemented when irreversible loss of kidney function occurs. Sometimes renal recovery is overlooked. From January 2005 to December 2014, we identified 28 patients hemodialyzed for more than 3 months who had renal replacement therapy discontinued. The group consisted of 17 (57.7%) males and 11 (42.3%) females. Patients were 18-87 years old. Time of hemodialysis ranged from 3 to 97 months. Of note, 14 (50%) patients were referred from local dialysis units for solution of vascular access problems...
