BACKGROUND: To address the rising concern about oncology drug costs, the American Society of Clinical Oncology (ASCO) and the National Comprehensive Cancer Network (NCCN) recently developed unique tools to help providers and patients make informed decisions about the value of an anticancer regimen. The ASCO Value Framework (AVF) allows users to generate a net health benefit (NHB) score along with drug acquisition costs for oncology regimens that have been compared in a prospective randomized clinical trial...

INTRODUCTION: Insomnia, muscular cramps, pruritus and postdialysis recovery time (RT) are quality-of-life parameters that affect hemodialysis (HD) patients physically and mentally. METHODS: We included 171 end-stage renal disease patients: 115 on high-flux HD and 56 on online hemodiafiltration (HDF). Patients were asked "How long does it take you to recover from a dialysis session?" and they evaluated intensity (absent, mild, medium and severe) of insomnia, muscular cramps and pruritus in the past 4 weeks...

A vascular access (VA) is used to facilitate hemodialysis in patients that suffer from end-stage renal disease. However, they suffer from high failure rates due to non-maturation and venous stenosis, with intimal hyperplasia (IH) the underlying cause of both conditions. Abnormal hemodynamic profiles, which arise following VA creation, are believed to lead to the development of IH. However, the exact physiological response that initiates this process is unknown. This review evaluates the different hemodynamic parameters that are hypothesised to correlate with the development of IH...

BACKGROUND: Intraoperative angiography is routinely utilized for aneurysms and arteriovenous malformations (AVMs) to verify complete occlusion and resection. Surgery for spinal and posterior fossa neurovascular lesions is usually performed in prone position. Intraoperative angiography in the prone position is challenging and there is no standardized protocol for this procedure. OBJECTIVE: To describe our experience with intraoperative angiography in the prone and lateral positions, using upper extremity arterial access...

The purposes of this study were to review historical changes in the classification of spinal arteriovenous (AV) shunts and to propose a practical classification system. The associated literature regarding the classification of spinal AV shunts was reviewed in the angiography era between 1967 and 2015. The classification systems of spinal AV shunts and a proposed classification system were presented with neuroradiological imaging and medical illustrations. There have been seven major classification systems based on the evolution of diagnostic methods as well as treatments for spinal AV shunts: the first description of spinal AV shunts diagnosed and classified using spinal angiography in 1971; the second classification based on a case report of intradural direct perimedullary arteriovenous fistulas (AVFs) treated by microsurgery in 1987; the third classification based on a case series of intradural perimedullary AVFs treated by endovascular interventions in 1993; the fourth and fifth classification systems based on a case series of spinal AVFs and arteriovenous malformations (AVMs) treated by microsurgery or endovascular interventions in 2002; the sixth classification based on a case series of cranio-spinal dural AV shunts in 2009; and the seventh classification based on a case series of extradural AVFs treated by microsurgery and endovascular interventions in 2011...

BACKGROUND/AIMS: All hemodialysis (HD) patients are generally recommended to create a fistula first; but to create a mature arteriovenous fistula (AVF) can be challenging in elderly individuals. It is unclear if elderly incident HD patients derive a survival benefit from an AVF over an arteriovenous graft (AVG) or a tunneled central venous catheter (TDC). METHODS: We examined the association of vascular access type (AVF, AVG, and TDC with and without a maturing AVF/AVG at dialysis transition) at HD initiation with all-cause, cardiovascular (CV), and infection-related mortality in 46,786 US veterans using Cox models with adjustment for confounders...

In a neonate with bradycardia and hypoxia, and clinical concern for critical congenital heart disease (CCHD), highly unusual ECG findings were present. These included a flatline Lead 1, and identical Leads 2, 3, and AVF. These abnormalities were due to bilateral arm to leg lead exchanges and not to heart disease. Complete cardiac workup including echocardiogram was normal.

PURPOSE: Arteriovenous fistula (AVF) of the cauda equina (CE) fed by the proximal radicular artery (PRA) is very rare, and the differentiation from that of the filum terminale (FT) is important to avoid treatment-related injury to the CE when endovascular treatment is selected. The authors describe a case of AVF of the CE fed by the PRA, demonstrate the anatomical features and discuss the treatment precautions. METHODS: A 69-year-old man presented with a transient weakness of lower limbs...

Multiple studies have shown that Staphylococcus aureus bacteremia (SAB) has been a major cause of death in hemodialysis patients. We examined whether SAB is a risk for mortality among chronic hemodialysis patients in Japan where the standard vascular access is arteriovenous fistula (AVF). This was a multicenter, retrospective study of maintenance hemodialysis patients with bloodstream infection (BSI) from 2011 to 2013 at tertiary care centers in Japan. The endpoint was hospital mortality. Our cohort contained 32 SAB cases (14 MRSA and 18 MSSA) and 42 non-SAB cases...

Dysfunctional uterine bleeding is a common presentation of women in the emergency department. We describe the case of a 33-year-old female who presented with intermittent spotting due to an acquired uterine AVF. The patient underwent a transvaginal pelvic ultrasound as well as a CT angiogram. The patient was treated conservatively and elected to undergo uterine artery embolization in an effort to preserve fertility. She successfully delivered a healthy baby boy at 39-week gestation via an emergent caesarian section due to a prolapsed umbilical cord 17 months after undergoing the uterine artery embolization...

BACKGROUND: Arteriovenous fistula (AVF) and arteriovenous fistula graft (AVG) access for hemodialysis can develop stenosis, eventually leading to thrombosis and access failure. Prompt endovascular intervention can salvage the access but restenosis does occur. Clinical course, restenosis pattern, and risk factors associated with initial stenosis of AVFs/AVGs in Asian hemodialysis patients were studied. METHOD: A retrospective study was conducted (January 2009-June 2012) on consecutive patients with renal failure who developed the first-time stenosis in the vascular access and were managed with endovascular intervention...

Arteriovenous fistulas (AVF) are an entity most commonly seen in the head and neck region. An AVF is a direct connection between the arterial feeders and the draining veins without intervening capillary beds (unlike an arteriovenous malformation in which a nidus intervenes between the arteries and veins). We describe a case of traumatic AVF in a child aged 9 years, who presented with a pulsatile scalp swelling following blunt trauma to the head. It turned out to be an AVF between the superficial temporal artery and vein...

OBJECTIVE: Arteriovenous fistulae (AVF) remain the optimal conduit for hemodialysis access but continue to demonstrate poor patency and poor rates of maturation. We hypothesized that CD44, a widely expressed cellular adhesion molecule that serves as a major receptor for extracellular matrix components, promotes wall thickening and extracellular matrix deposition during AVF maturation. APPROACH AND RESULTS: AVF were created via needle puncture in wild-type C57BL/6J and CD44 knockout mice...

A 78-year-old gentleman presented with recurrent symptomatic hemarthrosis after total knee arthroplasty. His workup revealed an iatrogenic arteriovenous fistula (iAVF). The iAVF was embolized with the Onyx Liquid Embolization System with resolution of his symptoms up to 10 months of follow-up. This is the first description to our knowledge of an iatrogenic hemarthrosis after total knee arthroplasty successfully treated with Onyx solution embolization.

BACKGROUND: Radio-cephalic arteriovenous fistula (RCAVF) is the gold standard vascular access for end-stage chronic kidney disease patients. Exercises after arteriovenous fistula (AVF) creation improve maturation. No articles are published regarding neuromuscular electrostimulation (NMES) in AVF maturation. OBJECTIVES: To assess the usefulness of a NMES programme on RCAVF maturation process. METHODS: An 8-week single-centre prospective study...

PURPOSE: Stenosis is the main cause of arteriovenous fistula (AVF) failure. It is still unclear whether surveillance based on vascular access blood flow (QA) enhances AVF function and longevity. METHODS: We conducted a three-year follow-up randomized, controlled, multicenter, open-label trial to compare QA-based surveillance and pre-emptive repair of subclinical stenosis with standard monitoring/surveillance techniques in prevalent mature AVFs. AVFs were randomized to either the control group (surveillance based on classic alarm criteria; n = 104) or to the QA group (QA measured quarterly using Doppler ultrasound [M-Turbo®] and ultrasound dilution [Transonic®] added to classic surveillance; n = 103)...

BACKGROUND: The possibility of coronary steal through an arteriovenous fistula (AVF) in hemodialysis (HD) patients with coronary artery bypass grafts (CABGs) using an ipsilateral internal thoracic artery (ITA) has been suggested. In order to define the significance of such a possibility, we analyzed cardiac events and mortality risk in patients in relation to AVF flow. METHODS: A retrospective cohort study was performed on prevalent HD patients from a single center...
