Vascular access in the elderly

Arif Asif, Mohamed M Bakr, Michael Levitt, Tushar Vachharajani
BACKGROUND: Conflicting data continue to surround the optimal dialysis access for the elderly. Many propose that catheters are the best option for this population; others emphasize the creation of an arteriovenous fistula. SUMMARY: While an arteriovenous access is the best available access, it has a high early failure rate, particularly in the elderly. However, significant differences exist in forearm (men ≥65 years ~70%; women ≥65 years ~80%) versus upper arm (men ≥65 years ~40%; women ≥65 years ~38%) fistula failure rates in the elderly, with upper arm having much lower failure rates...

Femoral and radial artery access continue to be the standard of care for percutaneous coronary interventions. Cardiac catheterization has progressed to encompass a wide range of diagnostic and interventional procedures including coronary, peripheral, endovascular, and structural heart disease interventions. Despite advanced technology to make these procedures safe, bleeding, and vascular complications continue to be a substantial source of morbidity, especially in patients undergoing large-bore access procedures...

Background: Balloons cannot pass through severely calcified coronary lesion (SCCL), and sometimes they cannot be opened at a high pressure even if they can pass through the lesion. There are limited data on rotational atherectomy (RA) via transradial access (TRA) in this setting. The aim of this study was to evaluate in-hospital and 1-year outcomes in elderly patients with SCCL who underwent RA via TRA. Methods: Eighty-six consecutive elderly patients with de novo SCCL who underwent RA were enrolled and divided into TRA (n = 45) and transfemoral access (TFA, n = 41) groups in this retrospective analysis from 2008 to 2013...

BACKGROUND: The number of elderly patients with end-stage renal disease is increasing rapidly. The higher prevalence of comorbidities and shorter life expectancy in these patients make it difficult to decide on the type of vascular access (VA). We explored the optimal choice for VA in elderly hemodialysis patients. METHODS: We included elderly patients (> 65 years) visiting our VA clinic and divided them into three groups as follows: radiocephalic arteriovenous fistula (AVF), brachiocephalic AVF, and prosthetic arteriovenous graft (AVG)...

INTRODUCTION: As the number of elderly end-stage renal disease patients lacking suitable vessels for arteriovenous fistula (AVF) is increasing, indications for tunnel cuffed catheters (TCCs) may be expanding. This study aimed to clarify changes over time in the number of patients with TCC and indications for TCCs. METHODS: This single-center retrospective study analyzed 143 catheters for 95 patients who inserted TCCs between July 2005 and July 2017. Patients were divided into two groups (early- and late-phase groups) based on the median observational period...

Life-sustaining haemodialysis requires a durable vascular access (VA) to the circulatory system. The ideal permanent VA must provide longevity for use with minimal complication rate and supply sufficient blood flow to deliver the prescribed dialysis dosage. Arteriovenous fistulas (AVFs) have been endorsed by many professional societies as the VA of choice. However, the high prevalence of comorbidities, particularly diabetes mellitus, peripheral vascular disease and arterial hypertension in elderly people, usually make VA creation more difficult in the elderly...

INTRODUCTION: The number of elderly patients requiring hemodialysis has increased, along with the need for multiple vascular access placements. Thus, the frequency of access creation using the upper arm veins, including transposed basilic arteriovenous fistula, has also increased. The purpose of this study was to identify the prevalence of anatomical variations in the upper arm veins on preoperative mapping venography and to investigate the implications of such variants on access creation...

There is no simple way to prescribe hemodialysis. Changes in the dialysis population, improvements in dialysis techniques, and different attitudes towards the initiation of dialysis have influenced treatment goals and, consequently, dialysis prescription. However, in clinical practice prescription of dialysis still often follows a "one size fits all" rule, and there is no agreed distinction between treatment goals for the younger, lower-risk population, and for older, high comorbidity patients. In the younger dialysis population, efficiency is our main goal, as assessed by the demonstrated close relationship between depuration (tested by kinetic adequacy) and survival...

Minimized length of hospitalization (LoS) and lower risk of hospitalization-related complications are key requirements in the treatment of aortic valve disease, mainly in the elderly candidates. Our objective was to evaluate evolution of LoS after surgical (SAVR) or transcatheter aortic valve implantation (TAVI) and its predictors. We enrolled 1,849 elderly (aged >75) patients receiving SAVR or TAVI from 2009 to 2016. In the surgical cohort (n = 1,006) the mean LoS slightly decreased from 13.81 ± 9.27 days (2009) to 10...

Background: Arteriovenous fistulas (AVFs) are the preferred vascular access type in most hemodialysis patients. However, the optimal vascular access type in octogenarians and older (≥80 years) hemodialysis patients remains widely debated given their limited life expectancy and lower AVF maturation rates. Methods: Among incident hemodialysis patients receiving care in a large national dialysis organization during 2007-2011, we examined patterns of vascular access type conversion in 1 year following dialysis initiation in patients <80 versus ≥80 years of age...

During the last ten years, transcatheter aortic valve implantation (TAVI) has become a reliable and valid alternative treatment for elderly patients with severe symptomatic aortic valve stenosis requiring valve replacement and being at high or intermediate surgical risk. While common femoral arteries are the access site of choice in the vast majority of TAVI patients, in up to 15-20% of TAVI candidates this route might be precluded due to the presence of diffuse atherosclerotic disease, tortuosity or small vessel diameter...

: Background: Establishing peripheral IV access for infusions is one of the most common invasive procedures performed in the hospital setting, but it isn't always successful on the first attempt. Multiple attempts delay treatment and cause stress in patients and nurses. The literature reports that venipuncture skills are among the most challenging for novice nurses to master. OBJECTIVES: The goal of this quality improvement (QI) initiative was to develop, validate, and refine a simple evidence-based tool that novice nurses can use in the clinical setting to better identify those patients with preexisting conditions or anatomical variances that result in difficult IV access...

Introduction: A lot of drug groups are associated with preventable drug-related admissions. Coumarin derivatives, prescribed for the treatment and prevention of deep vein thrombosis or pulmonary embolism or prevention of systemic embolism or stroke in patients with prosthetic heart valves or atrial fibrillation, are often associated with bleeding. The aim of our study was to analyze how the anticoagulant therapy with VKAs could affects the hospitalizations and the visits to emergency room in the elderly population (> 65 years old)...

Transfemoral transcatheter aortic valve implantation is an established therapy to treat elderly patients affected by severe aortic stenosis, who are considered to be at high or extreme risk for surgical aortic valve replacement. The transfemoral approach is contraindicated in patients with severe peripheral artery disease, small vessel size or severe tortuosity. In these patients, other vascular access routes such as transapical, subclavian or direct-aortic access may be considered. We describe the first case of a Medtronic Evolut R (Medtronic, Minneapolis, MN, USA) implantation made through the brachial artery in a 75-year-old patient affected by severe aortic stenosis...

RATIONALE & OBJECTIVE: National vascular access guidelines recommend placement of arteriovenous fistulas (AVFs) over grafts (AVGs) in hemodialysis patients, but have not been comprehensively assessed in the elderly. We evaluated clinically relevant vascular access outcomes in elderly patients receiving an AVF or AVG after hemodialysis therapy initiation. STUDY DESIGN: Retrospective cohort study using national administrative data. SETTINGS & PARTCIPANTS: Claims data from the US Renal Data System of 9,458 US patients 67 years and older who initiated hemodialysis therapy from July 1, 2010, to June 30, 2011, with a catheter and received an AVF (n=7,433) or AVG (n=2,025) within the ensuing 6 months...

Vascular access is of vital importance for patients requiring dialysis therapies. AV fistulas have been endorsed by many professional societies as the access of choice, however, subsequent creation does not go without consequences. As the population ages and patients become more medically complex, access failure has become a major cause of treatment complication. For the elderly, this is especially true and there are multiple decision points that require careful reflection before an AVF is placed. This article reviews access considerations for AVF placement in the elderly population and considers the possibility that the fistula first approach to vascular access should not be an absolute...
