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...

Acute upper limb ischemia is a rare, potentially limb- or life-threatening vascular emergency that may lead to limb dysfunction or amputation. We present a patient undergoing maintenance hemodialysis who was hospitalized for arteriovenous graft thrombus complicated by acute upper limb ischemia arising from thrombus shedding to the fingertip arteries during thrombolysis. We successfully restored fingertip arterial patency, avoided amputation, and recovered the function of the arteriovenous graft by precise thrombolysis, anticoagulation, correction of arteriospasm, and percutaneous transluminal angioplasty...

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...

In classic pancreatic transplantation, the splenic artery and vein are ligated at the tail of the pancreas graft. This leads to slowed blood flow in the splenic vein and may cause thrombosis and graft loss. In this study, a patient received a pancreas after kidney transplantation. A modified surgical technique was used in the pancreatic graft preparation. The donor splenic artery and vein were anastomosed end to end at the tail of the pancreas. The splenic artery near the anastomosis was partially ligated, and an effective diameter of 2 mm was reserved to limit arterial blood pressure and flow...

OBJECTIVE: The creation of an arteriovenous fistula (AVF) is considered the most effective hemodialysis (HD) vascular access. For patients who are not suitable for AVF, arteriovenous grafts (AVGs) are the best access option for chronic HD. However, conventional AVGs are prone to intimal hyperplasia, stenosis, thrombosis, and infection. Xeltis has developed an AVG as a potential alternative to currently available AVGs based on the concept of endogenous tissue restoration. The results of the first 6-month follow-up are presented here...

BACKGROUND: Chronic kidney disease (CKD) affects 10% of the global population costing over a hundred billion dollars per annum and leading to increased risk of cardiovascular disease. Many patients with CKD require regular haemodialyses. Synthetic arteriovenous grafts (AVG) are increasingly used to provide rapid vascular connection for dialysis. Initially, they have excellent patency rates but are critically limited by neointimal hyperplasia at the venous anastomosis, which drives subsequent thrombosis, graft failure and death...

INTRODUCTION: Brachial artery aneurysm (BAA) following long-standing arteriovenous fistula (AVF) ligation after renal transplantation is odd. CASE PRESENTATION: Two cases of brachial artery aneurysm treated with bypass (a saphenous vein graft and a PTFE graft). In the first patient no complications were recorded whereas an infection was diagnosed after 6 months from the procedure in the second treatment. CLINICAL DISCUSSION: Multiple factors activated by stress on the vessel wall followed by fistula ligation are the cause of vascular remodeling of the three layers making up the wall with possible evolution in aneurysmatic lesions...

INTRODUCTION: A central component in the introduction of a novel surgical procedure or technique is an evaluation of its cost efficiency when compared with a benchmark standard of care. Accurate assessment of costs is thus essential in ensuring appropriate allocation of resources within a healthcare system. The treatment of kidney failure requires a significant volume of resources, and vascular access provision is the main modifiable cost. The costs of providing this service are obscured by generic NHS reference costs, which lack adequate granularity to allow meaningful comparisons between treatments...
