Abstract Background and Aims Current literature suggests the arteriovenous fistula (AVF) to be the preferred type of vascular access for hemodialysis. However, AVFs have significant and potentially deleterious effects on cardiac functions particularly in the setting of preexisting heart disease. The aim of this study is to compare the clinical and echocardiographic evolution after creation of a proximal AVF and a radial AVF. Method We conducted a retrospective descriptive study including all chronic hemodialysis patients through AVF. Group 1 (G1) included patients with proximal AVF and group 2 (G2) patients with radial AVF. Results Twenty-four patients were collected in G1 and the average age was 55 years. G2 included 13 patients with a mean age of 44 years. Systolic blood pressure decreased after AVF creation in both groups (G1: 62.5%, G2: 45%, NS). A dyspnea was noted in 70% of cases of G1 and 38.4% of cases of G2 (NS). The interventricular septum was thickened in 20.8% of cases of G1 and 38.4% of G2 (NS). Left ventricular (LV) dilatation was observed in both groups with LV diastolic telegram diameter increase of 58% in G1 versus 10% in G2 (p = 0.04). A decrease in LV ejection fraction was found in 62.5% in G1 and 46.1% in G2 (p = 0.066). The major cardiac complications in G1 were acute coronary syndrome in 5 patients and atrial fibrillation in 4 cases after an average of 60 months and 35 months, respectively. No cardiac complications were noted in G2. Conclusion AVFs remain the preferred type of vascular access for chronic hemodialysis therapy because they are associated with better long-term patency and fewer complications compared with synthetic grafts. Its seat will depend on the vascular state and the cardiac status of the dialysis patient.

Arteriovenous Fistulas

Background: Despite national vascular access guidelines promoting the use of arteriovenous fistulas (AVF) over arteriovenous grafts (AVGs) for dialysis, AVF use is substantially lower in females. We assessed clinically relevant AVF and AVG surgical outcomes in elderly male and female patients initiating hemodialysis with a central venous catheter (CVC). Methods: Using the United States Renal Data System standard analytic files linked with Medicare claims, we assessed incident hemodialysis patients in the United States, 9,458 elderly patients (≥67 years; 4,927 males and 4,531 females) initiating hemodialysis from July 2010 to June 2011 with a catheter and had an AVF or AVG placed within 6 months. We evaluated vascular access placement, successful use for dialysis, assisted use (requiring an intervention before successful use), abandonment after successful use, and rate of interventions after successful use. Results: Females were less likely than males to receive an AVF (adjusted likelihood 0.57, 95% CI 0.52–0.63). Among patients receiving an AVF, females had higher adjusted likelihoods of unsuccessful AVF use (hazard ratio [HR] 1.46, 95% CI 1.36–1.56), assisted AVF use (OR 1.34, 95% CI 1.17–1.54), and AVF abandonment (HR 1.28, 95% CI 1.10–1.50), but similar relative rate of AVF interventions after successful use (relative risk [RR] 1.01, 95% CI 0.94–1.08). Among patients receiving an AVG, females had a lower likelihood of unsuccessful AVG use (HR 0.83, 95% CI 0.73–0.94), similar rates of assisted AVG use (OR 1.05, 95% CI 0.78–1.40) and AVG abandonment, and greater relative rate of interventions after successful AVG use (RR 1.16, 95% CI 1.01–1.33). Conclusions: While AVFs should be considered the preferred vascular access in most circumstances, clinical AVF surgical outcomes are uniformly worse in females. Clinicians should also consider AVGs as a viable alternative in elderly female patients initiating hemodialysis with a CVC to avoid extended CVC dependence.

The types of vascular accesses for hemodialysis (HD) include the native arteriovenous fistula (AVF), arteriovenous graft (AVG) and central venous catheter (CVC). Adequately matured native AVF is the best choice for HD patients and a high percentage of its presence is the goal of every nephrologist and vascular surgeon. This paper analyses the number and type of vascular accesses for HD performed over a 10-year period at the Clinical Center of Serbia, and presents the factors of importance for the creation of such a high number of successful native AVF (over 80%). Such a result is, inter alia, the consequence of the appointment of the Vascular Access Coordinator, whose task was to improve the quality of care of blood vessels in the predialysis period as well as of functional vascular accesses, and to promote the cooperation among different specialists within the field. Vascular access is the ?lifeline? for HD patients. Thus, its successful planning, creation and monitoring of vascular access is a continuous process that requires the collaboration and cooperation of the patient, nephrologist, vascular surgeon, radiologist and medical personnel.

The initiation of hemodialysis in patients with chronic kidney disease (CKD) requires vascular access formation. The choice of vascular access for individual patient depends on various factors however arteriovenous fistula (AVF) is conventionally considered to be the vascular access of choice. Once hemodialysis is initiated through a mature AVF, there is an ongoing need for surveillance of the AVF to ensure adequate function and prevent vascular access issues among which flow obstruction (both inflow and outflow) remains the most important. AVF stenosis can potentially lead to inadequate dialysis delivery and thrombosis thus leading to access loss. Physical examination and AVF Doppler ultrasonography (DUS) are useful for evaluation of stenosis in the  arteriovenous connection and the outflow tract. Periodic assessment of the AVF with Static Intra access Pressure (SIAPR) determination may be a reliable means of predicting vascular access stenosis. Material & Methods  A cross sectional study carried out at Department of Nephrology, Fatima Memorial Hospital, Lahore from July 2018 to December 2018. In total 113 patients were included, and all patients underwent SIAPR assessment and Doppler Ultrasound of AVF. Results Mean age of the patients was 56.81±9.38 years, male to female ratio of the patients was 1.8:1. In this study the SIAPR was suggestive of  stenosis in 87(76.99%) patients. The sensitivity, specificity and diagnostic accuracy of SIAPR against Doppler US of the AVF for detection of stenosis was 75.86%, 22.62% & 36.28% respectively Conclusion SIAPR has low specificity and diagnostic accuracy compared to Doppler US for detection of AVF stenosis.

The aim of our study is to report the results of two types (type A, type B) paclitaxel drug-coated balloon compared with standard percutaneous transluminal angioplasty in the treatment of juxta-anastomotic stenoses of mature but failing distal radiocephalic hemodialysis arteriovenous fistulas. Two groups of 26 and 44 patients treated with two different drug-coated balloon are compared with a control group of 86 treated with standard percutaneous transluminal angioplasty. A color Doppler ultrasound was performed to evaluate stenosis and for treatment planning. We assess primary patency, defined as the absence of dysfunction of the arteriovenous fistulas, patent lesion or residual stenosis < 30% and no need for further reintervention of target lesion. Primary patency and secondary patency are evaluated after 12 months with color Doppler ultrasound for the whole arteriovenous fistulas, defined as absolute (absolute primary patency, absolute secondary patency) and target lesion. Postprocedural technical and clinical success was 100%. After 12 months, absolute primary patency is 81.8% for type A, 84.1% type B, and 54.7% for standard percutaneous transluminal angioplasty; target lesion primary patency is 92% type A, 86.4% type B, and 62.8% standard percutaneous transluminal angioplasty; absolute secondary patency is 95.4% type A, 95.5% type B, and 80.7% standard percutaneous transluminal angioplasty; target lesion secondary patency is 100% type A, 97.7% type B, and 80.7% standard percutaneous transluminal angioplasty. All the patients treated with drug-coated balloon (type A + type B) have an absolute primary patency of 83.3%, a target lesion primary patency of 87.9%, an absolute secondary patency of 95.5%, and a target lesion secondary patency of 98.4%. Our study confirms that the use of drug-coated balloon, indiscriminately among different brands, improves primary patency with statistically significant difference in comparison with standard percutaneous transluminal angioplasty and decreases reintervention of target lesion in juxta-anastomotic stenoses of failing distal arteriovenous fistulas maintaining the radiocephalic fistula as long as possible.

INTRODUCTION The global increase of chronic renal failure has resulted in a growing number of patients on haemodialysis using arteriovenous fistulas (AVFs). By virtue of their very function, AVFs at times shunt blood away from regions distally, resulting in an ischaemic steal syndrome. Distal revascularisation with interval ligation (DRIL) has been described as a procedure to treat symptomatic ischaemic steal. We present our experience in the management of this complication. PATIENTS AND METHODS Six patients with severe ischaemic steal were treated using a DRIL procedure between May 2004 and June 2007. There were three males and three females, all with elbow brachiocephalic AVFs. Symptoms ranged from severe rest pain to digital gangrene. Published results from international studies of 135 DRIL procedures were also reviewed. RESULTS Vascular access was maintained along with the elimination of ischaemic symptoms in the six patients using an ipsilateral reversed basilic vein graft. Interval ligation of the distal brachial artery was performed at the same time. All patients showed immediate and sustained clinical improvement of symptoms with a demonstrable increase in digital pulse oximetry. CONCLUSIONS DRIL is a beneficial treatment option that has proven successful at alleviating ischemic steal symptoms and preserving vascular access. This avoids placement of central lines, its associated risks, and the need to create an alternative sited fistula.
