Insights

Central venous stenosis (CVS) in hemodialysis patients can be successfully treated with percutaneous transluminal angioplasty and stenting. This intervention demonstrated good patency rates, highlighting its effectiveness in managing this condition.

Area of Science:

  • Vascular Surgery
  • Interventional Cardiology
  • Nephrology

Background:

  • Central venous stenosis (CVS) significantly impacts hemodialysis access.
  • Percutaneous transluminal angioplasty (PTA) with stenting is a primary treatment for CVS.
  • Understanding procedural outcomes is crucial for patient management.

Observation:

  • Ten hemodialysis patients with CVS underwent PTA with or without stenting.
  • 90% of patients received PTA with primary stent insertion.
  • Procedures were performed under sedation by interventional cardiologists.

Findings:

  • Primary patency rates were 90% at 3 months, 70% at 24 months.
  • No association found between patient demographics or dialysis vintage and patency.
  • Successful treatment of CVS was achieved through angioplasty and stenting.

Implications:

  • Percutaneous angioplasty and primary stenting are effective for treating central venous stenosis.
  • Preventive strategies for CVS remain paramount despite successful interventions.
  • Further research may explore long-term outcomes and prevention methods.

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,...

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 III: Nursing Management

The nursing management of a patient undergoing hemodialysis includes several critical steps, starting with a thorough assessment before the procedure.Before the Hemodialysis ProcedureFirst, record the patient's vital signs—blood pressure, heart rate, respiratory rate, and temperature—to establish a baseline. This baseline is essential for detecting conditions such as hypotension that could impact the patient's response to dialysis. Document the patient's pre-dialysis weight, as this...

Continuous Renal Replacement Therapy01:30

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...

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
