Insights

Permanent dual lumen catheters (PDLC) offer crucial long-term hemodialysis access for patients unsuitable for other methods. These catheters demonstrate significant survival rates, though blockage and infection remain key complications.

Area of Science:

  • Nephrology
  • Vascular Surgery
  • Medical Devices

Background:

  • Permanent dual lumen catheters (PDLC) serve as an alternative vascular access for patients ineligible for arteriovenous fistula, arteriovenous graft, or peritoneal dialysis.
  • Long-term hemodialysis requires reliable vascular access, and PDLCs are increasingly utilized in specific patient populations.

Purpose of the Study:

  • To present the clinical experience and outcomes of using permanent dual lumen catheters for long-term hemodialysis.
  • To evaluate the efficacy, complications, and survival rates associated with PDLCs in a cohort of patients.

Main Methods:

  • A retrospective analysis of 101 PDLC insertions in 63 patients between January 1990 and April 1994.
  • Data collected included patient demographics, insertion site (predominantly subclavian vein), duration of use, complications, and reasons for removal.

Main Results:

  • The median duration of catheter use was 168 days, with a range of 5-1582 days.
  • Overall cumulative catheter survival rates were 94% at 6 months, 89% at 1 year, and 75% at 4 years.
  • Major complications included blockage (28%) and catheter-related infection (15%); death and blockage were primary reasons for removal.

Conclusions:

  • Permanent dual lumen catheters are vital for long-term dialysis access, particularly in patients with limited life expectancy.
  • PDLCs demonstrate favorable survival rates and should be considered a primary access option in selected hemodialysis patients.

Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in critically...

Peritoneal Dialysis I: Introduction and Procedure

Peritoneal dialysis (PD) is a procedure that facilitates the exchange of solutes, waste products, electrolytes, and excess fluid between the blood in the peritoneal capillaries and a dialysis solution introduced into the peritoneal cavity.Principles of Peritoneal Dialysis (PD)Diffusion: Waste products such as urea and electrolytes move from high concentrations in the blood to low concentrations in the dialysate across the peritoneal membrane. This mechanism is driven by the concentration...

Peritoneal Dialysis II: Peritoneal Dialysis Systems and Complications

Peritoneal dialysis (PD) is a medical process that removes waste products and excess fluid from the body using the peritoneal membrane as a natural filter.Peritoneal Dialysis MethodsSeveral methods can be used for peritoneal dialysis, including Acute Intermittent Peritoneal Dialysis, Continuous Ambulatory Peritoneal Dialysis, and Automated Peritoneal Dialysis, also known as Continuous Cyclic Peritoneal Dialysis.Acute Intermittent Peritoneal Dialysis (AIPD) is used for patients with uremic...

Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

Hemodialysis I: Introduction

Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

Hemodialysis II: Procedure and Complications

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...
