Central Venous Catheters for Hemodialysis-the Myth and the Evidence.

Kidney Int Rep 2021 Dec 11;6(12):2958-2968. Epub 2021 Oct 11.

Cleveland Clinic Lerner College of Medicine of Case Western Reserve University, Cleveland, Ohio, USA.

Hemodialysis-central venous catheter (HD-CVC) insertion is a most often performed procedure, with approximately 80% of patients with end-stage kidney disease in the United States initiating kidney replacement therapy through a HD-CVC. Certain adverse events arising from HD-CVC placement, including catheter-related bloodstream infections (CR-BSIs), thrombosis, and central vein stenosis, can complicate the clinical course of patients and lead to considerable financial impact on the health care system. Medical professionals with different training backgrounds are responsible for performing this procedure, and therefore, comprehensive operator guidelines are crucial to improve the success rate of HD-CVC insertion and prevent complications.

A pig model of tunneled dialysis catheter (TDC) infection and dysfunction: Opportunities for therapeutic innovation.

J Vasc Access 2021 Sep 23:11297298211046751. Epub 2021 Sep 23.

UNC Kidney Center, Chapel Hill, NC, USA.

Background: Although tunneled dialysis catheters (TDC) are far from ideal, they still represent the main form of vascular access for most patients beginning dialysis. Catheters are easy to place and allow patients instant access to dialysis, but regardless of these benefits, catheters are associated with a high incidence of significant complications like bloodstream infections, central venous stenosis, thrombosis, and dysfunction. In the present study, we aim to describe and characterize a swine model of catheter dysfunction and bloodstream infection, that recreates the clinical scenario, to help to serve as a platform to develop therapeutic innovations for this important clinical problem.

Tunneled femoral dialysis catheter: Practical pointers.

J Vasc Access 2021 Aug 21:11297298211039633. Epub 2021 Aug 21.

Department of Nephrology and Hypertension, Cleveland Clinic Foundation, Cleveland, OH, USA.

One of the most challenging aspects of providing end-stage kidney disease care is to achieve adequate long-term access to the bloodstream to support hemodialysis (HD) therapy. Although upper extremity arteriovenous fistula remains the vascular access of choice for patients on HD, complications such as central venous stenosis, access thrombosis, or exhaustion of suitable access sites in the upper extremity, ultimately result in pursuing vascular access creation in the lower extremity. The current review focuses on the indications, contraindications, and clinically relevant practical procedural tips to successfully place a tunneled femoral dialysis catheter. Read More

Transposition of the superficial femoral artery combined with ultrasound-guided returning-venous cannulation as a last resort for vascular access in a multi-complicated hemodialysis patient.

J Vasc Access 2021 Jun 6:11297298211023288. Epub 2021 Jun 6.

Department of Surgery, Saiwaicho Memorial Hospital, Okayama, Japan.

A superficialized artery as a blood-drawing route could be an option for vascular access (VA) in hemodialysis patients with cardiac failure, vessel damage, steal syndrome, and venous hypertension, and it could be a secondary VA option in those with repetitive vascular access troubles, routinely requiring a blood-returning venous route. The brachial artery is preferably used for superficialization due to the benefit of its appropriate diameter for cannulation, procedural ease of surgery under local anesthesia, and usable subcutaneous vein for blood-returning route in the upper limb. The superficial femoral artery (SFA) has also been reported as a candidate for arterial transposition; however, its subcutaneous transposition could have difficulties in requiring general anesthesia and securing blood-inflow-venous routes.
