Permanent haemodialysis catheter

INTRODUCTION: Paediatric vascular access is a demanding field. The need for a multidisciplinary team is mandatory in children with end-stage kidney disease (ESKD). Central venous catheters (CVCs) remain the preferred option worldwide. Recent emerging data demonstrated the benefits of using arteriovenous fistulas (AVFs) in the paediatric population for long-term vascular access. The small vessel size in children represents a surgical challenge for vascular access. CASE PRESENTATION: We report three cases from our haemodialysis department and the difficulty in maintaining permanent vascular access...

OBJECTIVES: To assess the patency of tunnel dialysis catheters and their results in patients in a tertiary care setting. METHODS: The retrospective-prospective, observational study was conducted at the Department of Interventional Radiology, Liaquat National Hospital, Karachi, from September 2021 to February 2022, and comprised records of patients who underwent tunnel dialysis catheters placement from July 2019 to December 2020. Data regarding age, gender, residence, comorbidity, catheter placement site, use of antibiotics before catheter insertion, reasons for catheter removal, and total catheter days was retrieved from the medical record...

A male adult patient on maintenance haemodialysis due to end-stage diabetic nephropathy presented with low-grade intermittent fever, cough and generalised weakness for 3 weeks. Initial blood investigations revealed an elevated neutrophil count with raised inflammatory markers. Chest CT revealed loculated hydropneumothorax with multiple cavitary nodules. Repeated blood cultures from the cuffed tunnelled catheter site and the right arm and sputum cultures were negative for pyogenic bacteria and yeast aetiology...

INTRODUCTION: Initiation of emergency dialysis is a critical situation responsible for high morbidity and mortality. This study describes the characteristics of emergency hemodialysis patients in a hospital in Madagascar. PATIENTS AND METHODS: It is a descriptive study over a period of 7 months, from September 1, 2018 to March 31, 2019, on emergency hemodialysis patients in the hemodialysis department of the University Hospital of Joseph Raseta Befelatanana, Antananarivo...

Patients on haemodialysis (HD) suffer a high mortality rate linked to developing subclinical hypoxic parenchymal stress during HD sessions. The oxygen extraction ratio (OER), an estimate of the oxygen claimed by peripheral tissues, might represent a new prognostic factor in HD patients. This study evaluated whether the intradialytic change in OER (ΔOER) identified patients with higher mortality risks. We enrolled chronic HD patients with permanent central venous catheters with available central venous oxygen saturation (ScvO2) measurements; the arterial oxygen saturation was measured with peripheral oximeters (SpO2)...

UNLABELLED: Patients requiring temporal or permanent catheter or arterio-venous fistula (AVF) for haemodialysis may be in challenging situation, if they are cardiovascular implantable electronic devices (CIED) carriers. MATERIALS AND METHODS: The authors analysed preoperative venogrphies of 3100 patients referred for transvenous lead extraction for a possible chance of safe haemodialysis catheter (HC) implantation or proper AVF function. RESULTS: A chance of safe catheter implantation parallel to existing leads reaches 68...

OBJECTIVE: To provide family physicians with an evidence-based overview on the various methods of vascular access for hemodialysis (HD) and to provide a framework for the clinical assessment of HD access. SOURCES OF INFORMATION: A MEDLINE literature search was conducted using the MeSH terms arteriovenous fistula , arteriovenous graft , central venous catheter , and hemodialysis (or haemodialysis ), including all relevant English-language articles published between January 1995 and September 2021...

BACKGROUND: Patients with kidney failure require vascular access to receive maintenance haemodialysis (HD), which can be achieved by an arteriovenous fistula or a central venous catheter (CVC). CVC use is related to frequent complications such as venous stenosis and infection. Venous stenosis occurs mainly due to trauma caused by the entrance of the catheter into the venous lumen and repeated contact with the vein wall.  A biofilm, a colony of irreversible adherent and self-sufficient micro-organisms embedded in a self-produced matrix of exopolysaccharides, is associated with the development of infections in patients with indwelling catheters...

Renal transplant is the first-line therapy in paediatric patients with end-stage renal disease (ESRD). Wong HS and Goh BL reported up to 79% of 1061 paediatric patients still require long-term haemodialysis (HD).1 The lack of deceased and living donors is attributable to the poor awareness, cultural and religious grounds. Permanent vascular access (PVA) in paediatrics therefore, serves more as a long term treatment rather than a bridging therapy. We observed 5 children and an adolescent, all with previous indwelling catheters, who underwent arteriovenous fistula (AVF) creation and report the outcomes...

Intradialytic hypotension (IDH) is a hemodynamic phenomenon recently associated with decreased blood oxygen saturation (SO2 ). The ratio between peripheral oxygen saturation (SpO2 ) and central venous SO2 (ScvO2 ) or Oxygen Extraction Ratio (OER), which represents a roughly estimate of the amount of oxygen claimed by peripheral tissues, might be used to estimate haemodialysis (HD) related hypoxic stress. Aim of this pilot study was to evaluate the relationship between OER increments during dialysis sessions (ΔOER) and episodes of IDH...

BACKGROUND: Patients with chronic kidney disease (CKD) who require urgent initiation of dialysis but without having a permanent dialysis access have traditionally commenced haemodialysis (HD) using a central venous catheter (CVC). However, several studies have reported that urgent initiation of peritoneal dialysis (PD) is a viable alternative option for such patients. OBJECTIVES: This review aimed to examine the benefits and harms of urgent-start PD compared to HD initiated using a CVC in adults and children with CKD requiring long-term kidney replacement therapy...

BACKGROUND: Reliable vascular access is key to sustainable haemodialysis treatment. Guidelines recommend an arteriovenous fistula (AVF) as the preferred modality in preference to arteriovenous grafts (AVGs) or central venous catheters (CVCs). There are limited data on vascular access in sub-Saharan Africa. This study aimed to evaluate the vascular access used in a South African tertiary hospital and identify problems with achieving the recommended access goals. METHODS: A cross-sectional analysis was performed of the haemodialysis programme at Livingstone Tertiary Hospital...

BACKGROUND: In chronic haemodialysis patients central veins occlusion occur very often. In such patients, permanent pacemaker placement implantation can be challenging and alternative approaches should be used. CASE SUMMARY: This is a case of 66-year-old male patient with complete atrioventricular block after a mitral valve (MV) surgery for endocarditis. The patient has a permanent surgically inserted haemodialysis catheter in right heart atrium after several unsuccessful attempts of endovascular recanalization of superior vena cava...

Tortuosity of the carotid artery is usually an asymptomatic vascular abnormality and is discovered accidentally during cerebral angiography. These vascular changes may aggravate surgical procedures in the neck region. We described a technique of permanent catheter insertion in patients with renal graft failure in whom renal replacement therapy was necessary. Severe tortuosity of cervical arteries may make this procedure more difficult, necessitating a special technique, that is, full image monitoring.

The aim of the present study is to share the experience of chronic peritoneal dialysis (PD) at King Hussein Medical Center, Amman, Jordan, and to highlight the complications of this procedure. This is a retrospective chart review study for all the children from day 1 of life to 14 years, who underwent chronic PD for end-stage renal disease (ESRD) during the period of 10 years extending from 2009 to 2019. The following data were collected: mode of dialysis, type of peritoneal dialysis, age of starting peritoneal dialysis, gender, aetiology of ESRD, duration on PD, complications and outcome...

Jugular Tesio lines (TesioCaths; MedCOMP, Harleysville, PA, USA) are frequently used as permanent vascular accesses in haemodialysis patients. During the insertion procedure, arrhythmias are a relatively common complication, usually related to an excessively advanced catheter tip, without major consequences. We present two cases of life-threatening arrhythmias triggered by the Tesio catheter eccentric high-velocity jet of blood resolved after reposition of the catheter without further episodes, despite both lines being inserted under real-time ultrasound and fluoroscopic guidance...

BACKGROUND: The impact of arteriovenous fistula (AVF) or graft (AVG) thrombosis on mortality has been sparsely studied. This study investigated the association between AVF/AVG thrombosis and all-cause and cardiovascular mortality. METHODS: The data from 2439 patients with AVF or AVG undergoing maintenance haemodialysis (HD) included in the A Study to Evaluate the Use of Rosuvastatin in Subjects on Regular Hemodialysis: An Assessment of Survival and Cardiovascular Events trial (AURORA) were analysed using a time-dependent Cox model...

INTRODUCTION: Arteriovenous fistulas (AVFs) are considered the best and safest modality for providing haemodialysis in patients with end-stage renal disease. Only 20% of UK centres achieve the recommended 80% target for achieving dialysis of the prevalent dialysis population via permanent access (as opposed to a central venous catheter). This is partly due to the relatively poor maturation rate of newly created fistulas, with as many as 50% of fistulas failing to mature.The Surveillance Of arterioveNous fistulAe using ultRasound study will examine whether a protocolised programme of Doppler ultrasound (US) surveillance can identify, early after creation, potentially correctable problems in those AVFs that subsequently fail to mature...

INTRODUCTION: Long-term use of peritoneal dialysis catheter is associated with complications such as infection and malfunction, necessitating removal of catheter with subsequent reinsertion or permanent transfer to haemodialysis. This study aims to investigate the outcome in patients who underwent reinsertion. METHODS AND MATERIALS: A single-centre retrospective study was performed in Singapore General Hospital for all adult incident peritoneal dialysis patients between January 2011 and January 2016...

Analysed herein are one-year results of formation of arteriovenous fistulas in 109 patients with end-stage chronic renal failure, as well as therapeutic decision-making after angiosurgical counselling of 144 patients presenting with 'problem' permanent vascular accesses. The counselling and formation of arteriovenous fistulas were carried out in conditions of interdepartmental collaboration between outpatient centres dealing with haemodialysis and vascular surgeons specialized in ultrasound mapping of peripheral vessels and performing different variants of arteriovenous fistulas...
