PURPOSE: Assess the feasibility of using a bovine carotid artery graft for buttonhole technique hemodialysis in patients who are not candidates for a native fistula. METHODS: Case reports used to demonstrate selection criteria and results for this approach. Criteria include: knowledgeable patient with prior dialysis experience, stable graft in place for 3 months minimum, not a candidate for a native fistula, and able to maintain close follow-up. RESULTS: Both grafts were based on axillary vessels and have been in place for a total of 64 months...

INTRODUCTION: Arteriovenous access (AVA)-related pain treated successfully with runoff-venous decompression of the causative nerve, following ultrasound (US)-assisted preoperative evaluation, has never been reported. CASE PRESENTATION: A 57-year-old man suffering from constant exhausting pains along the outflow cephalic vein of the radiocephalic arteriovenous fistula at the wrist and the antecubital fossa, was treated surgically after the diagnosis of AVA-related pain derived from cephalic vein compression on two peripheral cutaneous nerves, the superficial radial nerve (SRN) and the lateral antebrachial cutaneous nerve (LACN)...

BACKGROUND: Failure of maturation occurs in 30%-60% of arteriovenous fistula (AVF) creation for hemodialysis, with highest rates in distal radiocephalic fistulas. This is partly due to initial small blood vessel size with limited blood flow capacity. Forearm exercise has shown potential as stimulus for increasing blood vessel size in patients with end-stage renal disease (ESRD) and may promote maturation of AVFs in the upper limb when applied postoperatively. However, it is unknown if forearm exercise increases blood vessel size pre-operatively, which may contribute to more distal AVF creation and raise success rates of AVF surgery...

Herein, we report the case of a 44-year-old female with end-stage renal disease on hemodialysis. She was admitted to our hospital to evaluate if she was eligible for a kidney transplant. Transthoracic echocardiography showed a markedly dilated coronary sinus and an unexpected finding of increased right ventriculoatrial gradient. A saline contrast echocardiography to confirm the presence of persistent left superior vena cava (PLSVC) was not performed because of arteriovenous fistula (FAV) for hemodialysis on the left forearm...

Low rates of arteriovenous fistula (AVF) maturation prevent optimal fistula use for hemodialysis; however, the mechanism of venous remodeling in the fistula environment is not well understood. We hypothesized that the embryonic venous determinant Eph-B4 mediates AVF maturation. In human AVF and a mouse aortocaval fistula model, Eph-B4 protein expression increased in the fistula vein; expression of the arterial determinant Ephrin-B2 also increased. Stimulation of Eph-B-mediated signaling with Ephrin-B2/Fc showed improved fistula patency with less wall thickness...

BACKGROUND: Patients with end-stage renal disease undergoing hemodialysis (HD) have an elevated risk of cardiovascular disease-related morbidity and mortality. To prevent from such a life-threatening event, the continuous blood pressure (BP) monitoring system may contribute to detect BP decline in early stages and may help to do appropriate disposal. Our research team has introduced an electronic stethoscope (Asahi Kasei Co, Ltd., Tokyo, Japan), which translates sound intensity of Arteriovenous Fistula (AVF) to BP data using the technique of Fourier transformation that can predict continuous BP non-invasively...

Peritoneal dialysis (PD) interruption requiring hemodialysis (HD) is not uncommon and its frequently abrupt nature prevents timely creation of permanent HD access and avoidance of central venous catheters (CVC). We retrospectively studied a cohort of 24 end-stage renal disease (ESRD) patients (mean age 50.7 years, 83.3% African-Americans, 58.3% females, time on dialysis interquartile range [IQR] 0 - 65 days) who had simultaneous PD catheter insertion and backup arteriovenous fistula (AVF) creation between January 1, 2012, and December 31, 2013...

OBJECTIVE: This article describes the use of a transjugular venous access for interventions in upper extremity hemodialysis arteriovenous fistulas (AVFs) and grafts. This access is used in selected patients in whom direct puncture of the hemodialysis access is considered to be difficult or cumbersome. Technical success was achieved in 96.7% of patients. If an intervention is unsuccessful, the transjugular access offers the possibility of placement of a dialysis catheter for temporary or long-term hemodialysis...

Background: Vascular access for hemodialysis is best provided by an arteriovenous fistula (AVF). AVF fail primarily because of neointimal hyperplasia. Asymmetric dimethlyarginine (ADMA) is a naturally occurring analogue of L-arginine, which is elevated in renal failure and impairs endothelial cell function. ADMA inhibits nitric oxide synthetase, leading to impaired nitric oxide production and contributing to the development of neointimal hyperplasia. ADMA was measured at the time of AVF placement to evaluate associations with access failure...

OBJECTIVE: The urgency with which salvage of thrombosed vascular accesses for dialysis should be attempted remains unknown. We examined the effect of a timely thrombectomy approach on vascular access outcomes for dialysis. METHODS: A before-and-after study was conducted with patients on hemodialysis who had undergone endovascular thrombectomy. A timely thrombectomy initiative (ie, salvage within 24 hours of thrombosis diagnosis) was started in July 2015 at our institution...

Since the publication of the first vascular access clinical practice guidelines in 1997, the global nephrology community has dedicated significant time and resources toward increasing the prevalence of arteriovenous fistulas and decreasing the prevalence of central venous catheters for hemodialysis. These efforts have been bolstered by observational studies showing an association between catheter use and increased patient morbidity and mortality. To date, however, no randomized comparisons of the outcomes of different forms of vascular access have been conducted...

Arteriovenous fistulae are the preferred choice of vascular access in hemodialysis patients, however complications such as stenosis can lead to access failure or recirculation, which reduces dialysis efficiency. This study utilized computational fluid dynamics on a patient specific radio-cephalic fistula under hemodialysis treatment to determine the dynamics of access recirculation and identify the presence of disturbed flow. Metrics of transverse wall shear stress and oscillatory shear index were used to characterize the disturbed flow acting on the blood vessel wall, whilst a power spectral density analysis was used to calculate the any turbulence within the access...

AIM: Intimal hyperplasia remains the leading cause of late hemodialysis access stenosis or occlusion. This study assessed the influence of conventional immunosuppressive drugs on the patency of hemodialysis accesses in patients with a history of organ transplantation. MATERIALS AND METHODS: Between January 2002 and December 2007, 1,654 patients underwent an operation for hemodialysis access. 135 patients received immunosuppressive therapy (IT); of these, 115 underwent an operation for hemodialysis access after transplanted graft failure and 20 patients after liver transplantation...

Native arteriovenous fistula (AVF) is the favorite access for hemodialysis (HD). The National Kidney Foundation's Kidney Disease Outcomes Quality Initiative (KDOQI) recommends its creation in most patients with renal failure. Unfortunately, intensive efforts to promote native AVF in patients with marginal vessels have increased the rate of primary fistula failure. A non-functioning fistula prompts the use of central venous catheter (CVC) that, unlike AVF, has been associated with an increased risk of morbidity and mortality among patients receiving HD...

Despite medical achievements, the number of patients with end-stage kidney disease keeps steadily raising, thereby entailing a high number of surgical and interventional procedures to establish and maintain arteriovenous vascular access for hemodialysis. Due to vascular disease, aneurysms or infection, the preferred access-an autogenous arteriovenous fistula-is not always available and appropriate. Moreover, when replacing small diameter blood vessels, synthetic vascular grafts possess well-known disadvantages...

The aim of this retrospective study was to assess epidemiology and echocardiographic findings of pericardial effusion in canine patients and to determine the clinical usefulness and safety of a new pericardiocentesis technique, using a "fistula needle" for hemodialysis. A database of 5304 dogs of different breeds, age, gender, type, and severity of the cardiac disease, referred for a specialist cardiology and echocardiographic examination from 2009-2016, was reviewed. All the dogs were subjected to echocardiography; when possible and required, an echo-guided pericardiocentesis was performed by mean of a 17G "fistula needle" commonly used for hemodialysis...
