Rationale & Objective: Clinical practice guidelines discourage the use of central venous catheters (CVCs) for vascular access in dialysis. However, some patients have inadequate vessels for arteriovenous fistula creation or choose to use a dialysis catheter. The risks associated with CVC use and their relationship to patient age are poorly characterized. Read More

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.

Tunneled central venous catheters used for the provision of hemodialysis are associated with excess morbidity and mortality. Catheter related exit site and blood stream infections are major risks of their use. Although catheter-avoidance is the best strategy to reduce infections and mortality in the hemodialysis population, the use of catheters remains unacceptably high. Read More

In most situations, central catheters are implanted in the right jugular vein as initial access for hemodialysis. However, after repeated punctures, the proximal vessels become stenosed and thrombosed and misplacement is likely to occur. Correct catheter position in the vein can be easily ascertained with X-ray or cross-sectional CT imaging. Read More

Patients with end-stage kidney disease who are considering home hemodialysis (HHD) face the challenge of learning to self-cannulate their arteriovenous access. Current practice discourages the use of tunneled central venous catheters, with recent indications that self-cannulating patients have superior outcomes. Patient-level barriers do not appear to preclude a successful HHD program and should not be viewed as insurmountable by healthcare staff or patients. Read More

Vascular Institute of New York, Brooklyn, NY, USA.

Objective: It has been a widely accepted practice that a previous placed pacemaker, automatic implantable cardioverter defibrillators, or central line can be a contraindication to placing a hemodialysis catheter in the ipsilateral jugular vein. Fear of dislodging pacing wires, tunneling close to the battery site or causing venous obstruction has been a concern for surgeons and interventionalists alike. We suggest that this phobia may be unfounded. Read More

Department of Anaesthesia, Great Ormond Street Hospital, London - UK.

Introduction: The peripherally inserted central catheters (PICCs) are vascular access devices (VAD) that are increasingly being used in the pediatric population. If a small vein caliber prevents positioning the catheter in the arm, the following step is to position the same catheter in the supraclavicular area, which can be defined as an off-label use or "atypical" approach, first described by Pittiruti.

Materials And Methods: We retrospectively reviewed PICC positioning with puncture-site in the supra-clavicular area ("atypical" PICC insertion) and then tunneled on the chest. Read More

Nephrology Center, Toranomon Hospital Kajigaya, Kanagawa, Japan.

Background/aims: All hemodialysis (HD) patients are generally recommended to create a fistula first; but to create a mature arteriovenous fistula (AVF) can be challenging in elderly individuals. It is unclear if elderly incident HD patients derive a survival benefit from an AVF over an arteriovenous graft (AVG) or a tunneled central venous catheter (TDC).

Methods: We examined the association of vascular access type (AVF, AVG, and TDC with and without a maturing AVF/AVG at dialysis transition) at HD initiation with all-cause, cardiovascular (CV), and infection-related mortality in 46,786 US veterans using Cox models with adjustment for confounders.
