BACKGROUND: With the increasing frequency of tunneled hemodialysis catheter use there is a parallel increase in the need for removal and/or exchange. A small but significant minority of catheters become embedded or 'stuck' and cannot be removed by traditional means. Management of embedded catheters involves cutting the catheter, burying the retained fragment with a subsequent increased risk of infections and thrombosis. Endoluminal dilatation may provide a potential safe and effective technique for removing embedded catheters, however, to date, there is a paucity of data...

BACKGROUND: Randomized controlled trials evaluate the effectiveness of interventions for central venous access devices, however, high complication rates remain. Scoping reviews map the available evidence and demonstrate evidence deficiencies to focus ongoing research priorities. METHOD: A scoping review (January 2006-December 2015) of randomized controlled trials evaluating the effectiveness of interventions to improve central venous access device outcomes; including peripherally inserted central catheters, non-tunneled, tunneled and totally implanted venous access catheters...

Problems related to hemodialysis access are a significant cause of morbidity and mortality in patients with end-stage renal disease. Physicians of all specialties who are involved in the placement and maintenance of vascular access for hemodialysis must have a long-term strategy for sequential placement of autogenous fistulas, transpositions, and prosthetic grafts to preserve access sites and to avoid long-term use of tunneled dialysis catheters. The Fistula First and KDOQI initiatives have provided strategies and algorithms for access placement in patients with chronic kidney disease...

K S Saravana, A A Zainal
OBJECTIVE: Central vein occlusion is a common complication related to central vein catheter insertion for haemodialysis which can be unmasked by an ipsilateral fistula creation, leading to a dysfunctional arteriovenous fistula (AVF). We describe an extra-anatomical venous bypass surgical procedure performed to maintain vascular access and reduce the symptoms of swelling of the ipsilateral upper limb, neck and face. MATERIALS AND METHODS: We report 20 consecutive patients with end-stage renal failure (ESRF) who had central vein occlusion and were not amenable to endovascular intervention...

BACKGROUND: Vascular access (VA) is the lifeline of hemodialysis patients. Although the autonomic nervous system might be associated with VA failure (VAF), it has never been addressed in previous studies. This study aimed to evaluate the predictive values of the heart rate variability (HRV) indices for long-term VA outcomes. METHODS: This retrospective study was conducted using a prospectively established cohort enrolling 175 adult chronic hemodialysis patients (100 women, mean age 65...

The term "stuck catheter" refers to situations where a central venous catheter cannot be removed from the central veins or right atrium using standard technique, usually due to development of a fibrin sheath leading to adherence to SVC or right atrial wall. Endoluminal dilatation is an interventional radiology technique that has been previously reported in the removal of stuck hemodialysis catheters, and to the best of our knowledge, this case describes the first application of the technique to remove a hemodialysis catheter that was adherent to SVC wall and transvenous pacemaker leads...

BACKGROUND: Optimising filter life and performance efficiency in continuous renal replacement therapy has been a focus of considerable recent research. Larger high quality studies have predominantly focussed on optimal anticoagulation however CRRT is complex and filter life is also affected by vascular access, circuit and management factors. We performed a systematic search of the literature to identify and quantify the effect of vascular access, circuit and patient factors that affect filter life and presented the results as a meta-analysis...

PURPOSE: Tunneled central venous catheters (tCVCs) are routinely used for long-term venous access in children with cancer and chronic diseases. They may be inserted by surgical venous cut-down or percutaneously. The aim of this study was to compare the operative times and intraoperative complications of both techniques. METHODS: This study compared group A (surgical venous cut-down, years 2002-2006) with group B (percutaneous, years 2008-2012). Patient characteristics, operative times, and intraoperative complications were obtained from surgical reports...

Central venous catheters (CVCs) are an important tool in the treatment of children. The insertion of a catheter may result in different complications depending of the type of catheter, the technique used for the insertion and the location. There are various techniques to reduce the risk of complications. In order to reduce the rate of complications of CVCs it is indispensable to perform a risk-benefit analysis for the individual patient before every insertion. The type of catheter used (for example tunneled catheters versus not-tunneled catheters) influences the rate of catheter-associated infections and the comfort of the patient significantly...

REVIEW
Julie Jaffray, Mary Bauman, Patti Massicotte
The use of central venous catheters (CVCs) in children is escalating, which is likely linked to the increased incidence of pediatric venous thromboembolism (VTE). In order to better understand the specific risk factors associated with CVC-VTE in children, as well as available prevention methods, a literature review was performed. The overall incidence of CVC-VTE was found to range from 0 to 74%, depending on the patient population, CVC type, imaging modality, and study design. Throughout the available literature, there was not a consistent determination regarding whether a particular type of central line (tunneled vs...

PURPOSE: Central venous catheters (CVC) are associated with increased infection rates, morbidity and mortality compared to other hemodialysis vascular access. Chlorhexidine-impregnated transparent (CHG-transparent) dressings allow for continuous antimicrobial exposure and easy visibility of the CVC insertion site. We conducted a quality improvement project to compare catheter-related infection (CRI) rates in two dressing regimens - CHG-transparent dressings and adhesive dry gauze dressing in hemodialysis patients with tunneled CVCs...

BACKGROUND: Trabectedin has shown efficacy against soft tissue sarcomas (STS) and has manageable toxicity. Trabectedin is administered through central venous access devices (VAD), such as subcutaneous ports with tunneled catheters, Hickman catheters and PICC lines. Venous access related adverse events are common, but have not yet been reported in detail. METHODS: A retrospective analysis of patient files of STS patients receiving trabectedin monotherapy between 1999 and 2014 was performed in all five STS referral centers in the Netherlands...

BACKGROUND: As of now, only a few studies have focused on the failure of tunneled cuffed venous catheter (tCVC) and mortality of hemodialysis (HD) patients using tCVC as long-term vascular access, whose vascular condition for arteriovenous fistula was not very satisfactory. In this study, we aimed to provide information about the first tCVC failure and survival rates of patients in this population. METHODS: Fifty-nine patients who used tCVC from January 1, 2009 to December 31, 2014 in our HD center were analyzed in this retrospective study and followed up either until their death or until December 31, 2015...

AIM: To investigate whether the type of dressing used (occlusive vs semi-occlusive) impacts on exit-site infection (ESI). BACKGROUND: Exit-site infections are a major predisposing factor for peritoneal dialysis (PD)-related peritonitis, the main cause of technique failure and an important cause of mortality. Care taken in exit-site dressing is considered an important procedure for the prevention of trauma and contamination of this area. Nevertheless, to our knowledge, no study has yet analyzed the impact of different dressing types on early ESI (up to 2 months after catheter insertion)...
