2021年12月1日 · HD-CVC is a type of central venous access device specifically designed to facilitate kidney replacement therapy in patients without a functioning long-term HD vascular access.

2024年12月3日 · In this installment of AJKD ’s Core Curriculum in Nephrology, we review the hemodialysis vascular access which is needed to establish a connection between the patient’s circulation and the HD machine. The 2 main categories of vascular access are the arteriovenous access (AV access) and central venous catheter (CVC).

Hemodialysis requires access to the central veins that can provide rapid extracorporeal blood flow ranging from 300 to 400 mL/min for three to four hours three times a week with minimal complications.

Central venous catheters (CVCs) are used to provide adequate hemodialysis (HD) in patients who are initiating dialysis or are awaiting maturation of more permanent vascular access such as an arteriovenous fistula (AVF) or (less desirable) arteriovenous graft (AVG).

2021年10月11日 · 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.

Air embolus is a potential catastrophic complication of CVCs and the relative risk while accessing a CVC is high. Ways to reduce the risk: Use needle-less HD connectors at all times for all patients dialyzing with a CVC. Clamp CVC limbs prior to flushing/connect/disconnect procedures (rationale: in case connector becomes loose or damaged).

A well-functioning vascular access (VA) is a mainstay to perform an efficient hemodialysis (HD) procedure. There are three main types of access: native arteriovenous fistula (AVF), arteriovenous graft, and central venous catheter (CVC). AVF, ...

2024年4月2日 · A central venous catheter for HD (HD CVC) is a medical device that provides a viable alternative for vascular access when long-term access cannot be established. CVCs used in dialysis have a larger lumen diameter than the CVCs used for intravenous infusions, to support adequate flows for HD treatment [ 1 ].

4 天之前 · One cohort study of 1041 patients treated with maintenance HD reported a 9%, 15%, and 2% risk of catheter-related bacteremia, functional impairment, and central stenosis, respectively, one year after retention CVC. Maintaining good function of the catheter is a prerequisite for the success of hemodialysis treatment.

HD-CVC is a type of central venous access device specifically designed to facilitate kidney replacement therapy in patients without a functioning long-term HD vascular access.
