Insights

Percutaneous transluminal angioplasty (PTA) for central venous disease (CVD) in hemodialysis patients increases vascular access flow but does not affect cardiac function. This study evaluated cardiac function, etiology, and treatment in these patients.

Area of Science:

  • Nephrology
  • Cardiology
  • Vascular Surgery

Background:

  • Central venous disease (CVD) is a common complication in hemodialysis (HD) patients, often leading to impaired vascular access.
  • Increased vascular access flow post-percutaneous transluminal angioplasty (PTA) may impact cardiac function in HD patients.

Purpose of the Study:

  • To evaluate cardiac function, etiology, and treatment outcomes in hemodialysis patients with central venous disease (CVD).
  • To assess the relationship between increased vascular access flow after PTA and cardiac function in HD patients.

Main Methods:

  • Retrospective study of 26 hemodialysis patients with CVD treated with PTA between June 2006 and February 2013.
  • Analysis of vascular access types, CVD locations, computed tomography findings, PTA success rates, and patency rates.
  • Evaluation of cardiac function parameters including left ventricular ejection fraction and inferior vena cava diameter pre- and post-PTA.

Main Results:

  • PTA success rate was 96%, with primary patency rates at 12 months of 57%.
  • Brachial artery flow volume significantly increased post-PTA (1306 vs. 957 ml/min; p=0.005).
  • No significant changes were observed in left ventricular ejection fraction (57% vs. 60%; p=0.2) or inferior vena cava diameter (17 vs. 17 mm; p=0.9) post-PTA.

Conclusions:

  • Increased vascular access flow following PTA for CVD in hemodialysis patients is not associated with adverse effects on cardiac function.
  • PTA is an effective treatment for central venous disease, improving vascular access flow without compromising cardiac status.

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,...

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

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...

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

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...
