Abstract Objective: The objective was to increase the understanding of vascular access in hemodialysis and evaluate hemodialysis-related anticoagulation treatments and the associated hemorrhagic or thrombotic complications. Materials and Methods: In this study, an epidemiological investigation was conducted in 1175 patients who underwent hemodialysis in seven blood purification centers in northern Chinese. The patients were divided into two groups based on the vascular access they used: Arteriovenous fistula (AVF) group and central venous catheter (CVC) group. The similarities and differences of anticoagulation and hemorrhagic, thrombotic complications were compared between two groups. Results: Arteriovenous fistula was the most frequently used vascular access, and heparin was the most commonly used anticoagulant. Patients in CVC group experienced significantly greater rates of low molecular weight heparin (LMWH) administration and had a higher rate in achieving thrombotic complications than those in AVF group. There were no significant differences in LMWH dosages in patients with thrombotic complications, as well as the proportion of patients who received anti-platelet drugs. Heparinized catheter lock solutions were excessively high in this study, which may lead to a risk of hemorrhage. Conclusion: Hemodialysis-related anticoagulation treatments in China require additional improvements, especially for the patients using CVC as vascular access. There is an urgent need to develop clinical evaluation studies of anticoagulation treatments for achieving more standardized and targeted treatments.

A well-functioning vascular access is a mainstay to perform an efficient hemodialysis procedure, which directly affects the quality of life in hemodialysis patients. We use three main types of access: native arteriovenous fistula, arteriovenous graft, and central venous catheter. Arteriovenous fistula remains the first and best choice for chronic hemodialysis. It is the best access for longevity, the lowest related complications, and for this reason, arteriovenous fistula use is strongly recommended by guidelines from different countries, including Vietnam. In practice, well-functioning arteriovenous fistula creation is not always simple. In this case, arteriovenous fistula creation with vein transposition or translocation is certainly useful. When native vein options have been exhausted, prosthetic can be used as the second option of maintenance hemodialysis access alternatives. Central venous catheters are very common and have become an important adjunct in maintaining patients on hemodialysis. In Bach Mai hospital, we certainly create about 1000 new arteriovenous fistulas every year (among these, about 84.98% new hemodialysis patients start hemodialysis without permanent accesses and depend on temporary central venous catheters) and successfully matured arteriovenous fistula rate is 92.6%. Among hemodialysis population in Bach Mai, 2.29% have arteriovenous grafts and 2.81% of patients still depend on cuffed tunneled catheters. The preferable locations for catheter insertions are the internal jugular and femoral veins. Proper vascular access maintenance requires integration of different professionals to create a vascular access team. Percutaneous transluminal angioplasty is not available. In our circumstance, we have achieved some advantages for hemodialysis patients but still a big gap to an advanced country.

One of the complications of arteriovenous fistulas in chronic hemodialyzed patients is the onset of an aneurysm which can be at risk of rupture. Traditional surgical repair is not always feasible and may not be successful in these cases, leading therefore to the loss of a functioning vascular access and requiring in any case the temporary use of a central venous catheter to allow regular hemodialysis sessions. We applied to this kind of aneurysm the same experience developed in the management of major arterial aneurysms and we considered endografting repair a good alternative in this case. In this paper we present the successful treatment of an arteriovenous fistula aneurysm using that technique. A distal radio-cephalic arteriovenous fistula in one of our patients presented an aneurysm with high risk of rupture. The endografting repair with percutaneous insertion of a Wallgraft™ endoprosthesis was well tolerated and the vascular access could be used the day after, without the need for a central venous catheter insertion.

Background: Vascular access is one of the most important outcome determinant of patients on hemodialysis. In Bangladesh increasingly more patients are started on hemodialysis as a lifesaving procedure. But we lack organized data on different aspects of dialysis practice. Data related to vascular access is even more scanty. Method: A survey was undertaken in one of the busy dialysis centers in Dhaka with a large number of patients on maintenance hemodialysis .Data were collected by doctors in dialysis units from patients along with records kept in the dialysis unit during November and December 2017. Results: Total 143 patients were included. 53% of these patients belonged to age group 61 to 80 years, 39% to age group 41 to 60 years; 56.6 % female and 43.4% male. 73.4% of the study patients received dialysis via central venous catheter at the initiation. But among the prevalent patients during study period, 84% patient were receiving dialysis via arterio-venous fistula and 5% via arterio-venous graft as permanent vascular access. Among these permanent vascular access left forearm was used in 47% and left upper arm in 33% of cases. Vascular ultrasound mapping before permanent access creation was done in only about 40% of cases. Almost 56 % of the vascular access surgery was done by experienced medical graduates in vascular access creation without any post graduate surgical qualifications. Conclusion: Vascular access data should be collected in a structured manner so that dialysis practice pattern of different centers and regions of the country can be compared. Similar data from several centers around the country will increase scope of improvement . Birdem Med J 2020; 10(2): 120-124

Background: The factors associated with the inability to start hemodialysis with an arteriovenous fistula (AVF) in chronic kidney disease patients are not fully understood. Aim: Evaluating factors associated with type of vascular access at the first chronic hemodialysis and at 1 year after it. Methods: The study cohort includes patients registered in the Regional Dialysis and Transplant Registry of Lazio undergoing first hemodialysis between 2008 and 2015. Logistic regression models were used to evaluate the association between socio-demographic, clinical and care/organizational factors, and vascular access at first hemodialysis. Cox regression models were used to assess the odds of switching to AVF during the first year of hemodialysis among patients starting dialysis with central venous catheter (CVC). Results: In the cohort of 6208 incident hemodialysis patients, 52.7% had an AVF and 47.3% had a CVC. Among the 2939 incident patients with CVC, 27.4% switched to FAV after 1 year. A higher probability of starting dialysis with AVF was observed among males (OR = 1.83; 95% CI 1.63–2.06), while a lower probability was observed among patients aged >85 years (OR 0.64; IC 95% 0.51–0.80). Patients with early referral to a nephrologist had a triple probability of start dialysis with AVF. We observed a higher odds of switch to AVF among males (HR = 1.62; 95% CI 1.40–1.89) and a lower odds among patients over 65 years. Conclusion: The observed high rate of AVF at the start of hemodialysis and of the switch from CVC to AVF in the first year, although declining since 2008, is a positive outcome. However, over one-third of patients maintain the CVC as vascular access for the first year because of unmodifiable factors, such as gender, age, comorbidity. The present study suggests that logistics/management and assistance/welfare problems may contribute to the delay or lack of AVF placement in incident hemodialysis patients or within the first year of dialysis.

Objectives: To determine the vascular access modalities used for hemodialysis, the reasons for choosing them, and determinants of satisfaction with vascular access among patients with end-stage renal disease. Methods: The American Association of Kidney Patients Center for Patient Research and Education used the American Association of Kidney Patients patient engagement database to identify eligible adult hemodialysis patients. Participants completed an online survey consisting of 34 demographic, medical history, and hemodialysis history questions to determine which vascular access modalities were preferred and the reasons for these preferences. Results: Among 150 respondents (mean age 54 years, 53% females), hemodialysis was most frequently initiated with central venous catheter (64%) while the most common currently used vascular access was arteriovenous fistula (66%). Most (86%) patients previously received an arteriovenous fistula, among whom 77% currently used the arteriovenous fistula for vascular access. Older patients and males were more likely to initiate hemodialysis with an arteriovenous fistula. The factors most frequently reported as important in influencing the selection of vascular access modality included infection risk (87%), physician recommendation (84%), vascular access durability (78%), risk of complications involving surgery (76%), and impact on daily activities (73%); these factors were influenced by patient age, sex, and race. Satisfaction with current vascular access was 90% with arteriovenous fistula, 79% with arteriovenous graft, and 67% with central venous catheter. Conclusion: Most end-stage renal disease patients continue to initiate hemodialysis with central venous catheter despite being associated with the lowest satisfaction rates. While arteriovenous fistula was associated with the highest satisfaction rate, there are significant barriers to adoption that vary based on patient demographics and perception of procedure invasiveness.

Objective: Permanent access in the form of a fistula is the preferred form of vascular access for most pediatric patients on maintenance hemodialysis (HD) therapy; however, the technical aspects of the procedure that are unique to the pediatric population, the expectation of a short waiting time for kidney transplantation and the need to cannulate every other day (with the pain and fear associated with it) limit its use. Our objective was to analyze the long-term outcomes of pediatric arteriovenous fistulas in our institution. Methods: A retrospective review was performed of all arteriovenous fistula (AVF) created in a HD population aged 0 to 18 years at a single institution from 2007 to 2019. Data abstracted included age, weight, etiology of renal failure, time on dialysis, central venous catheter history and transplantation history. Data were analyzed to determine the primary and secondary patency. Results: During the study period, 19 AVFs were performed in 16 patients, of whom 9 patients (56.3%) were male. Mean patient age was 12.3 years (range 5-17 years), and mean weight was 38.3kg (range 12-83kg). At the time of AVF creation, 9 patients were on dialysis and 7 patients had a central venous catheter (CVC), with a median length of CVC dependence of 10 months. Procedures performed included 4 radiocephalic fistulas, 11 brachiocephalic fistulas and 4 brachiobasilic. Five accesses failed to mature (26.3%). Mean follow-up was 6 years. The 2-year primary and secondary patency rates were 92.3% and 100%, respectively. The 4-year primary and secondary patency rates were 76.9% and 100%, respectively. No thrombosis was documented during follow-up. During the postoperative period, 10 patients (62.5%) received a kidney transplant, in a mean time of 23 months. Conclusions: AVFs demonstrate excellent long-term patency in pediatric HD patients. No significant complications were reported and no thrombosis occurred.

BackgroundAn autologous arteriovenous fistula (AVF) is the preferred hemodialysis vascular access, but successful creation is hampered by high rates of AVF failure. This study aimed to evaluate patient and surgical factors associated with AVF failure to improve vascular access selection and outcomes.MethodsThis is a post hoc analysis of all participants of FAVOURED, a multicenter, double-blind, multinational, randomized, placebo-controlled trial evaluating the effect of fish oil and/or aspirin in preventing AVF failure in patients receiving hemodialysis. The primary outcome of AVF failure was a composite of fistula thrombosis and/or abandonment and/or cannulation failure at 12 months post-AVF creation, and secondary outcomes included individual outcome components. Patient data (demographics, comorbidities, medications, and laboratory data) and surgical factors (surgical expertise, anesthetic, intraoperative heparin use) were examined using multivariable logistic regression analyses to evaluate associations with AVF failure.ResultsOf 536 participants, 253 patients (47%) experienced AVF failure during the study period. The mean age was 55±14.4 years, 64% were male, 45% were diabetic, and 4% had peripheral vascular disease. Factors associated with AVF failure included female sex (odds ratio [OR], 1.79; 95% confidence interval [CI], 1.20 to 2.68), lower diastolic BP (OR for higher DBP, 0.85; 95% CI, 0.74 to 0.99), presence of central venous catheter (OR, 1.49; 95% CI, 1.02 to 2.20; P=0.04), and aspirin requirement (OR, 1.60; 95% CI, 1.00 to 2.56).ConclusionsFemale sex, requirement for aspirin therapy, requiring hemodialysis via a central venous catheter, and lower diastolic BP were factors associated with higher odds of AVF failure. These associations have potential implications for vascular access planning and warrant further studies.

Buttonhole cannulation has been suggested as a technique that may lead to a reduction in many complications when compared with other techniques such as rope-ladder cannulation. Despite all above, some complications still continue, which may lead to a dysfunction of the arteriovenous fistula (AVF) and inadequate dialysis, having an impact on the quality of life of the patients or eventually making the vascular access unusable. We report a 47-year-old Chinese male with end-stage renal disease who had maintenance hemodialysis three times a week for 5 years. The AVF on the left wrist was operated 5 years ago and proved to be functionally effective with some monitoring and surveillance measures in the fourth year of hemodialysis. Two months later, the buttonhole cannulation technique was applied due to fistula punctuation difficulty by previous aneurysmal dilatation. After 10 times of buttonhole cannulation, the edema on the left forearm of the patient indicated a dysfunction of the AVF. This was further confirmed by the HD02 hemodialysis monitor and a vascular ultrasound, revealing a recirculation of 87%, an abnormal fistula between the AVF and the vein together with thrombus, and aneurysmal dilatation near the anastomosis. The site of cannulation was changed to avoid heavy recirculation (reduced to 25%), and a new AVF on the left wrist was successfully operated. Abnormal fistula on the AVF and vein during buttonhole cannulation is rarely reported, which reminds us that vascular access surveillance should be done regularly before and during the process of construction to find a possible dysfunction of the AVF in patients undergoing buttonhole cannulation.
