BACKGROUND: Vascular access problems are leading causes of morbidity, hospitalization, and impaired quality of life in chronic hemodialysis patients. Native arteriovenous fistula is the gold standard of vascular access. Geriatric nutritional risk index (GNRI), has recently been shown to be an easy and objective instrument for assessing nutritional status in these patient groups. Considering the association between arteria-venous fistula patency and inflammation, as well as the fact that inflammation is a component of malnutrition, the objective of this study was to determine the relation of malnutrition identified by GNRI with fistula patency...

Although randomised controlled trials (RCT) are considered the optimal form of evidence, there are relatively few in surgery. Surgical RCT are particularly likely to be discontinued with poor recruitment cited as a leading reason. Surgical RCT present challenges over and above those seen in drug trials as the treatment under study may vary between procedures, between surgeons in one unit, and between units in multi-centred RCT. The most contentious and debated area of vascular access remains the role of arteriovenous grafts, and thus the quality of the data that is used to support opinions, guidelines and recommendations is critical...

INTRODUCTION: Acute respiratory distress syndrome (ARDS) is defined in critically ill patients with acute hypoxemia and positive-pressure ventilation in association with several clinical disorders including trauma, pneumonia, sepsis, and aspiration. The prone position has been used for many years and is now recommended for patients with severe or moderate-to-severe ARDS on invasive mechanical ventilation. Acute kidney injury (AKI) is a common complication in patients with ARDS, with up to a 35% incidence rate...

BACKGROUND: Ultrasound guidance increases the success rate of peripheral intravenous catheter placement. However, the longer time required to obtain ultrasound-guided access poses difficulties for ultrasound beginners. Notably, interpretation of ultrasonographic images is considered as one of the main reasons of difficulty in using ultrasound for catheter placement. Therefore, an automatic vessel detection system (AVDS) using artificial intelligence was developed. This study aimed to investigate the effectiveness of AVDS for ultrasound beginners in selecting puncture points and determine suitable users for this system...

INTRODUCTION: The traditional sutured venous anastomosis used during arteriovenous graft implantation is associated with a high incidence of subsequent stenosis that is attributed to neointimal hyperplasia. Hyperplasia results from multiple factors, including hemodynamic abnormalities and vessel trauma during implantation. A novel anastomotic connector device was designed to provide an alternative, less traumatic, endovascular venous anastomosis that may ameliorate the clinical challenges associated with a sutured anastomosis...

INTRODUCTION: The long-term survival and low complication rate of autogenous fistulas for hemodialysis access is often offset by early thrombosis and slow or failed maturation leading to the use of central venous catheters. A regenerative material may have the potential to overcome these limitations. A completely biological acellular vascular conduit was investigated in this first-in-human clinical study. METHODS: With approval of the ethics board and patients' informed consent, five subjects were enrolled based on predetermined inclusion criteria...

Acuseal arteriovenous graft is an early cannulation graft having a tri-layered structure with an elastomeric middle layer. However, delamination of Acuseal grafts has been reported recently. This article describes two cases with different characteristics of Acuseal delamination. In case 1, the delamination occurred 1 month after a percutaneous transluminal angioplasty (PTA); therefore, the PTA was suspected to be a trigger. The delamination was located between the outer expanded polytetrafluoroethylene (ePTFE) layer and the elastomeric middle layer...

INTRODUCTION: Intravenous catheters present complications to patients, such as dislodgment, pistoning, micromovement, and infection. Despite the use of transparent dressings, a significant rate of I.V. catheter complications still arise. This article is to provide a scientific and technological perspective on how bonding a transparent dressing to a substrate using 2-octyl cyanoacrylate and n-butyl cyanoacrylate (OBCA) via multiple methods can significantly enhance the adhesion strength of the transparent dressing product, which subsequently increases the securement strength of the catheter...

Iatrogenic arteriovenous fistula (AVF) is a complication accompanying venous and arterial puncture. Herein we report a case of ligation closure of an iatrogenic AVF in the brachial artery after percutaneous coronary intervention (PCI) for the patient with end-stage kidney disease (ESKD). A 68-year-old woman presented with a history of several coronary angiographies (CAG) and PCI through the right brachial artery. After PCI, the patient experienced a thrill in the right elbow. Two years later, the patient initiated hemodialysis (HD) using a temporary HD catheter for ESKD and congestive cardiac failure...

We report a case series of four patients with radial artery occlusion complicating vascular access who were scheduled for coronary angiography. We describe the challenges in selecting adequate vascular access in patients with a history of coronary angiography and percutaneous coronary intervention, as well as the benefits of using preprocedural ultrasound examination of forearm arteries to detect radial artery occlusion. Our case series suggests that if the anterior interosseous artery provides partial blood supply to the hand as a collateral circulation of the occluded radial artery, the transulnar approach may be an alternative safe option for coronary angiography and percutaneous coronary intervention in this population...

BACKGROUND: Vascular access is the lifeline for patients on hemodialysis. The average survival rates of dialysis dependent patients have been improving over the last 5 years and hence their dialysis access needs longevity for uninterrupted optimal dialysis. With the lack of genomic vascular access failure predictors, there is an unmet need for predicting an event and the appropriate approach to mitigate recurrence of the event that could have cost and outcome implications. METHODS: We performed a single center experience that extracted relevant clinical (access flow, laboratory data and CKD details), access intervention (prior interventions, type & location of lesion, type of balloon used, use of stents etc...

BACKGROUND: Though arteriovenous grafts (AVG) mature more reliably than arteriovenous fistulae (AVF) and require fewer maturation procedures (MP) to obtain functional patency, AVG are thought to have worse function after maturation. We explored differences in post-maturation outcomes between the following groups: AVF patients who did (AS-AVF) and did not (unAS-AVF) require assisted maturation and AVG patients who did (AS-AVG) and did not (unAS-AVG) require assisted maturation. METHODS: Using the US Renal Data System (2012-2017), we retrospectively identified patients who initiated dialysis with a central venous catheter, underwent AVF or AVG placement and achieved successful two-needle cannulation...

BACKGROUND: Complications after removal of totally implanted vascular access devices. (TIVADs) have not been studied widely. The aim of this study was to assess the prevalence and risk factors of these complications. METHODS: This was a single-center retrospective study conducted in Gustave Roussy hospital in Villejuif, Ile-de-France, France. All adult patients scheduled for TIVAD removal between January 2015 and November 2019 were eligible for the study. The record of complications was compiled by noting the reason for a surgical or emergency department consultation during the month following removal, and also by calling the patients during the week of TIVAD removal to assess whether surgical advice was needed...

Stenosis or obstruction of neck great veins represent a frequent and severe complication in hemodialysis patients. Endovascular treatment with percutaneous transluminal angioplasty and/or stenting of these veins is the gold standard to restore patency. However, the jugular vein is frequently overstented in these cases and this might lead to persistent symptomatology of those patients also losing an access for future catheter placement. Herein, we present the 6-months performance of a Y-shaped stenting of the brachiocephalic and internal jugular vein leading to complete resolution of the symptoms, and maintenance of the jugular vein access...

BACKGROUND: Central venous catheters (CVCs) provide an immediate hemodialysis access but are considered to be of elevated risk for complications. It remains unclear, if CVCs per se have relevant impact on clinical outcome. We provide an assessment of CVC-associated complications and their impact on mortality. METHODS: In a single center retrospective study, CVC patients between JAN2015-JUN2021 were included. Data on duration of CVC use, complications and comorbidities was collected...
