Insights

Arteriovenous access banding is effective for high flow access and haemodialysis access-induced distal ischaemia. Ultrasound guidance is key to preventing complications and ensuring success in vascular access procedures.

Area of Science:

  • Vascular Surgery
  • Nephrology
  • Interventional Radiology

Background:

  • High flow access (HFA) and haemodialysis access-induced distal ischaemia (HAIDI) are common complications of arteriovenous (AV) access.
  • AV access banding is a potential treatment option for these conditions.

Purpose of the Study:

  • To validate the effectiveness and safety of AV access banding for HFA and HAIDI.
  • To assess the incidence of complications, particularly thrombosis, associated with the procedure.

Main Methods:

  • Retrospective study of 119 patients undergoing AV access banding for HFA or HAIDI.
  • Analysis of patient demographics, comorbidities, symptoms, and intraoperative ultrasound findings.
  • Definition and tracking of technical failure and complications like thrombosis, rupture, and aneurysm.

Main Results:

  • Primary clinical success was achieved in 71.4% of patients, with a secondary success rate of 84.9%.
  • The HAIDI group was older and had a higher prevalence of diabetes.
  • Older age and intraoperative ultrasound control were significantly associated with primary success.

Conclusions:

  • AV access banding is an effective procedure for both HFA and HAIDI.
  • The study did not find a high incidence of thrombosis, contrary to previous reports.
  • Intraoperative ultrasound control is crucial for preventing technical failure and improving outcomes.

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...

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.

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,...
