INTRODUCTION: Arteriovenous fistulas and grafts are lifelines for most hemodialysis patients, and a low access flow rate often requires patency-related intervention, such as angioplasty or thrombectomy, to prevent access failure. We examined whether early access flow rate, measured after initial fistula/graft cannulation, predicts vascular access patency-related intervention within 1 year. METHODS: This was a single-center retrospective cohort study. Among 172 patients undergoing surgical creation of a fistula/graft, 52 (30...

BACKGROUND: In this study, we evaluated our surgical approach in requiring surgical treatment of brachiocephalic arteriovenous fistula (AVF) aneurysms for salvage of AVF. METHODS: Between 2012 and 2022, 20 patients (16 men, 4 women; mean age 54.5 years) who were surgically treated for a brachiocephalic AVF aneurysm in our Cardiovascular Surgery Clinic were evaluated retrospectively. These 20 patients were operated on for aneurysm thrombosis and fistula failure in 16 patients, sudden rupture and severe bleeding in 3 patients, cosmetic reasons, and anxiety in 1 patient...

BACKGROUND: Introducing new procedures and challenging established paradigms requires well-designed randomised controlled trials (RCT). However, RCT in surgery present unique challenges with much of treatment tailored to the individual patient circumstances, refined by experience and limited by organisational factors. There has been considerable debate over the outcomes of arteriovenous grafts (AVG) compared to AVF, but any differences may reflect differing practice and potential variability...

IMPORTANCE: Hemodialysis requires reliable vascular access to the patient's blood circulation, such as an arteriovenous access in the form of an autogenous arteriovenous fistula or nonautogenous arteriovenous graft. This Review addresses key issues associated with the construction and maintenance of hemodialysis arteriovenous access. OBSERVATIONS: All patients with kidney failure should have an individualized strategy (known as Patient Life-Plan, Access Needs, or PLAN) for kidney replacement therapy and dialysis access, including contingency plans for access failure...

Current vascular access options require frequent interventions. In situ tissue engineering may overcome these limitations by combining the initial success of synthetic grafts with the long-term advantages of autologous vessels by using biodegradable grafts that transform into autologous vascular tissue at the site of implantation. Scaffolds(6mm-Ø) made of supramolecular polycarbonate-bisurea(PC-BU), with a polycaprolactone(PCL) anti-kinking-coil, were implanted between the carotid artery and jugular vein in goats...

BACKGROUND: Although end stage renal disease patients who undergo hemodialysis frequently experience dialysis-associated thrombotic complications, there remains a paucity of literature comparing the efficacy of different endovascular salvage techniques for grafts and fistulas. This study aims to compare primary patency in dialysis access following salvage mechanical thrombolysis/thrombectomy with a rotational thrombolysis device versus balloon maceration. METHODS: Using a database of patient records at a tertiary medical center, all patients who underwent rotational thrombectomy with the Cleaner XT™ Rotational Thrombectomy System for endovascular salvage of arteriovenous fistula or arteriovenous graft from August 2016 to July 2022 were included in the population...

A definitive randomised controlled trial of arteriovenous fistula (AVF) versus arteriovenous grafts (AVG) has been advocated for more than a decade, but as yet, none has been completed. The aim of this article is to summarise the theoretical barriers, review the difficulties in trial design and practicalities that have thus far prevented this from occurring.

BACKGROUND: A well-functioning vascular access (VA) is crucial for the patients on maintenance hemodialysis (HD). Central venous stenosis (CVS) is a common, yet, overlooked complication of VA as its diagnosis is challenging. Moreover, its effect on the flow volume (FV) and the peripheral resistive index (RI) was not well discussed before. Despite the availability of doppler ultrasound (DUS) in most centers, direct visualization of central veins using DUS is quite difficult. METHODS: This is a retrospective single-center self-controlled cohort study that was conducted in a specialized vascular access management tertiary center in Japan and included all patients with CVS who underwent percutaneous transluminal angiography (PTA) with or without vascular stenting in the period from January 2014 to September 2022...

Arteriovenous fistulas (AVFs) of the lower extremity are uncommon. The main causes are traumatic or iatrogenic, with 15% of traumatic AVFs occurring in the popliteal vessels. Herein, we present a 60-year-old female with a traumatic AVF caused after a car accident 40 years ago. The patient presented with right leg venous claudication and symptoms of congestive heart failure. Duplex ultrasound of lower limb vessels revealed an AVF at the distal part of the tibiofibular trunk. The patient was successfully managed with an endovascular approach using a coil-assisted covered endovascular repair technique of the tibiofibular bifurcation (CERTIFIB) with excellent results and distal vessels patency...

Arterial spin labeling (ASL) and three-dimensional (3D) time-of-flight (TOF) magnetic resonance angiography (MRA) are sensitive tools to detect dural arteriovenous fistula (DAVF), but hyperintensity in these images is also caused by jugular venous reflux. We present a case of a patient with renal failure on hemodialysis with retrograde flow into the internal jugular vein (IJV) mimicking DAVF. A 74-year-old man with a radial arteriovenous fistula for hemodialysis experienced transient dizziness. The TOF MRA and ASL revealed high signal intensity, suggesting the presence of a DAVF in the left transverse and sigmoid sinuses and the IJV...

Femoral arteriovenous access is most commonly used in endovascular diagnosis and treatment. Complications arising during femoral arteriovenous access include hematoma, retroperitoneal hemorrhage, pseudoaneurysm, and arteriovenous fistula. A 66-year-old woman diagnosed with paroxysmal atrial fibrillation was treated with catheter ablation. This patient had a high femoral artery bifurcation, and we punctured the femoral vein by the conventional Merkmal method, which led to a femoral vein puncture through the deep femoral artery...

OBJECTIVES: Although forearm arteriovenous fistulas (AVFs) are the preferred initial vascular access for hemodialysis based on national guidelines, there are no population-level studies evaluating trends in creation of forearm versus upper arm AVFs and arteriovenous grafts (AVGs). The purpose of this study was to report temporal trends in first-time permanent hemodialysis access type, and to assess the effect of national initiatives on rates of AVF placement. METHODS: Retrospective cross-sectional study (2012 to 2022) utilizing the Vascular Quality Initiative (VQI) database...

OBJECTIVES: Prior studies have found lower arteriovenous fistula (AVF) creation rates in Black and Hispanic patients. Whether this is due to health care disparities or other differences is unclear. Our objective was to evaluate the racial/ethnic differences in initial surgical access type within a high volume, safety net system with predominantly Black and Hispanic populations. METHODS: A retrospective review of initial hemodialysis access in consecutive cases between 2014 and 2019 was conducted from all five safety net hospitals in a healthcare system that primarily treats underserved patients...

Arteriovenous fistula (AVF) formation after penetrating injury underscores a rare and challenging complication of vascular trauma. Traumatic AVFs have various clinical presentations and reported methods of repair. Although open surgical repair is the most frequently used method of repair, the advancement of endovascular techniques has been increasingly used during the past 3 decades. We report a case of an acute traumatic AVF of the superficial femoral artery and superficial femoral vein from a gunshot wound repaired with a unique endovascular technique involving snaring to establish through-and-through access to allow deployment of a covered stent graft...

We have reviewed the development and current status of therapies based on exposure to non-ionizing radiation (with a photon energy less than 10 eV) aimed at suppressing the venous neointimal hyperplasia, and consequentially at avoiding stenosis in arteriovenous grafts. Due to the drawbacks associated with the medical use of ionizing radiation, prominently the radiation-induced cardiovascular disease, the availability of procedures using non-ionizing radiation is becoming a noteworthy objective for the current research...

BACKGROUND: Patients who present with problems with definitive dialysis access (arteriovenous fistula (AVF) or arteriovenous graft (AVG)) become catheter dependent (temporary access), a condition that often carries a higher risk of infections, central venous occlusions and recurrent hospitalisations. For AVG, primary patency rates are reported to be 30% to 90% in patients undergoing thrombectomy or thrombolysis. According to the National Kidney Foundation-Kidney Disease Outcomes Quality Initiative (NKF-KDOQI) guidelines, surgery is preferred when the cause of the thrombosis is a stenosis at the site of the anastomosis in thrombosed AVF...

BACKGROUND: The superficial veins are commonly used in conventional autogenous arteriovenous fistulas and the placement of prosthetic grafts. When they are unsuitable, however, the use of the deep veins (venae comitantes) is generally considered to be a reasonable alternative. This study conducted a comparative analysis of clinical outcomes for arteriovenous grafts between 2 groups based on the type of venous outflow: superficial veins or venae comitantes. METHODS: In total, 151 patients who underwent arteriovenous grafts from November 2005 to March 2022 were retrospectively analyzed...
