Insights

Percutaneous transluminal angioplasty (PTA) effectively treats central vein stenosis in dialysis patients. While re-interventions are common, endovascular procedures preserve shunt function long-term.

Area of Science:

  • Vascular Surgery
  • Interventional Radiology
  • Nephrology

Background:

  • Central vein stenosis or occlusion significantly impacts haemodialysis shunt function.
  • Percutaneous interventions are explored to manage these vascular complications.

Purpose of the Study:

  • To evaluate the long-term outcomes of percutaneous transluminal angioplasty (PTA) for central vein stenoses or occlusions in patients requiring haemodialysis.

Main Methods:

  • 26 patients with haemodialysis shunts underwent 28 primary PTAs and 5 re-PTAs.
  • Stent implantation was performed in 3 patients; 10 re-PTAs were conducted to maintain stent patency.

Main Results:

  • Technical success rate for primary interventions was 96% (100% for stenoses, 50% for occlusions).
  • Primary post-PTA patency rates were 70% at 3 months, 60% at 6 months, and 30% at 12 months.

Conclusions:

  • PTA, with potential stent implantation, is a primary treatment for central venous system stenoses and occlusions.
  • Endovascular treatment can maintain long-term dialysis shunt function despite frequent re-interventions.

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...

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 measurement...

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 IV: Nursing Management

Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration. Review medication intake, particularly oral contraceptives,...
