Abstract Background and Aims According to local resources, different vascular access (VA) procedures are employed in every country. In Italy, high variability exists in VA management among different dialysis units. In 2018, the DOPPS 5 study showed a declining prevalence of lower arm arteriovenous fistulas (AVF) in Europe with an increasing tendency of making upper arm AVFs and placing central venous catheters (CVCs). Accordingly, an Italian Survey in 2013 confirmed an increasing trend in CVCs use among different Italian regions. Hence, we made an epidemiologic, multicenter study to evaluate a possible relation between this trend and the variability of local VA management policies. Method VA data from 236 patients of prevalent patients were collected from five dialysis centers in the South of Italy. The prevalence of the various types of VAs was analyzed in relation to the following different VA surgery policies adopted in the participant centers: Results Age of patients was comparable among all centers while dialysis vintage was higher in center A (P<0.001). The prevalence of lower arm AVFs was significantly reduced In Center A (50.6%) and the prevalence of CVCs (25.8%) was significantly increased as compared to the Centers D-E. On the contrary the Centers D-E had the highest prevalence of lower arm AVF (70.8%) and the lowest of CVCs (12.3%), with a statistically significant difference as compared to Center A (Table 1 ). Conversely, no differences were noticed when comparing data from Centers B-C vs. Center A and vs. Centers D-E, although the prevalence of lower arm AVFs was slightly higher, but the difference was not significant, and that of CVCs was slightly lower as compared to Center A ,fully supported by the vascular surgeon (Figure 1 ). Conclusion The reduced tendency of lower arm fistulas and the increasing prevalence of CVCs showed by the DOPPS 5 study might not be applicable to all Italian regions. In our study of 5 dialysis units in the South of Italy, the stability of the nephrologist’s surgical activity probably played a crucial role in explaining the observed decreased use of CVCs with a steadily high prevalence (over 70%) of the lower arm fistulas, regardless of aging.

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.

Prolonged use of central venous catheters (CVCs) for hemodialysis (HD) is associated with greater morbidity and mortality when compared with autogenous arteriovenous fistulas (AVF). The objective was to assess compliance with CVC guidelines in adults referred for hemoaccess at a county teaching hospital. Out of 256 patients, 172 (67.2%) were male, with a mean age of 50.0 ± 12.4 years. Overall 62.5 per cent initiated dialysis via CVC. Patients were divided into two groups (those with CVC (62.5%) and those without (37.5%)). Male gender was associated with initiation of dialysis via CVC versus no CVC (72.5 vs 58.3%, P = 0.02), as was a history of prior vascular access (P < 0.01). There were no significant differences between the groups regarding age, diabetes, smoking, ambulatory status, or insurance status. There were no differences in gender, age, insurance status, or prior vascular access between prolonged CVC use (≥90 days) and short-term CVC use (<90 days). We conclude that most patients initiated HD with CVC and exceed the recommended CVC duration. Men are more likely to initiate HD via CVC. Insurance status was not associated with CVC use. Multidisciplinary action may address barriers to reducing CVC duration.

Introduction: Despite the higher rate of morbidity and mortality, the use of central venous catheters has increased significantly compared to arteriovenous fistula. So far, no ideal organic solution has been identified for the prevention of thrombosis and catheter-related infection in patients undergoing hemodialysis. Objectives: This study aimed to evaluate the efficacy of Taurolock versus saline 5% on the prevention of catheter dysfunction and catheter-related infections. Patients and Methods: Seventy patients with chronic kidney disease, who requiring hemodialysis or those with permanent hemodialysis catheters referring to hemodialysis centers of Ahvaz, were selected and randomly divided into two groups, while 68 patients remained until the end of the study. In the first group, saline 5% was inserted into the lumen of catheter after each hemodialysis, and then catheter was blocked. In the second group, Taurolock solution (TauroLock™ -Hep 500®: Taurolidine; antimicrobial agent), citrate 4% and heparin (UI/mL) were used as antibiotics. Results: No significant difference between the catheter-related infection and positive blood culture in both saline and Taurolock groups was detected (2.94% versus 2.94%; P >0.05). Moreover, the catheter-related dysfunction in the saline 5% group was 5% less than the Taurolock group (2.94% versus 11.76%, P = 0.365). Conclusion: The results showed that saline 5% is at least as effective as a Taurolock solution for prevention of infections and catheter dysfunction. Saline is an effective, inexpensive, safe and readily available in various settings. Therefore, it could be considered as a proper alternative solution for reduction of dialysis-related side effects and costs.

Background: Central venous catheters (CVCs) have been essential devices for the treatment of children with hematological and oncological disorders. Only few studies investigated the complications and selections of different types of CVCs in these pediatric patients. This study aimed to compare risk factors for unplanned removal of two commonly used CVCs, i.e., peripherally inserted central catheters (PICCs) and tunneled CVCs, and propose better device selection for the patient. Procedure: This retrospective, single center cohort analysis was conducted on pediatric patients with hematological and oncological disorders inserted with either a PICC or a tunneled CVC. Results: Between January 1, 2013, and December 31, 2015, 89 patients inserted with tunneled CVCs (total 21,395 catheter-days) and 84 with PICCs (total 9,177 catheter-days) were followed up until the catheter removal. The median duration of catheterization was 88 days in PICCs and 186 days in tunneled CVCs (p = 1.24×10-9). PICCs at the 3-month cumulative incidence of catheter occlusion (5.2% vs. 0%, p = 4.08×10-3) and total unplanned removal (29.0% vs 7.0%, p = 0.0316) were significantly higher, whereas no significant difference was observed in the cumulative incidence of central line-associated bloodstream infection (11.8% vs. 2.3%, p = 0.664). Multivariable analysis identified younger age (<2 years) (subdistribution hazard ratio [SHR], 2.29; 95% confidence interval [CI], 1.27–4.14) and PICCs (SHR, 2.73; 95% CI, 1.48–5.02) were independent risk factors for unplanned removal. Conclusion: Our results suggest that tunnel CVCs would be a preferred device for children with hematological and oncological disorders requiring long-term, intensive treatment.

Abstract Introduction: Arteriovenous fistulas (AVF) are the best hemodialysis vascular accesses, but their failure rate remains high. Few studies have addressed the role of the vascular surgeon's skills and the facility's practices. We aimed to study these factors, with the hypothesis that the surgeon's skills and facility practices would have an important role in primary failure and patency rates at 12 months, respectively. Methods: This was a single-center, prospective cohort study carried out from March 2005 to March 2017. Only incident patients were included. A single surgeon made all AVFs, either in the forearm (lower) or the elbow (upper). Vascular access definitions were in accordance with the North American Vascular Access Consortium. Results: We studied 113 AVFs (65% lower) from 106 patients (39% diabetics, 58% started with catheter). Time to first connection was 21.5 days (IR: 14 - 31). Only 14 AVFs (12.4%) underwent primary failure and 18 failed during the first year. Functional primary patency rate was 80.9% (SE 4.1) whereas primary unassisted patency rate, which included PF, was 70.6% (4.4). Logistic regression showed that diabetes (OR = 3.3, 95%CI 1.38 - 7.88, p = .007) and forearm location (OR = 3.03, 95CI% 1.05 - 8.76, p = 0.04) were predictors of AVF failure. Patency of lower and upper AVFs was similar in non-diabetics, while patency in diabetics with lower AVFs was under 50%. (p = 0.003). Conclusions: Results suggest that a long-lasting, suitable AVF is feasible in almost all patients. The surgeon's skills and facility practices can have an important role in the long term outcome of AVF.

Percutaneous Insertion

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.

Indwelling central venous catheters were used for vascular access in 25 oncology patients, The lines were used for sampling, administration of blood products, chemotherapeutic agents, parenteral nutrients and occasionally plasmapheresis. The complication rate was no higher than in reported series in which the catheters were reserved for parenteral nutrition. We believe that a central venous cannula can be safely used as the sole means of vascular access in those patients with consequent psychological and practical benefits.
