Summary
Arteriovenous fistulas (AVFs) for dialysis face challenges with maturation and stenosis, impacting cannulation. This review explores endovascular techniques to improve AVF success rates and dialysis access.
Area of Science:
- Vascular Surgery
- Nephrology
- Interventional Radiology
Background:
- Arteriovenous fistulas (AVFs) are the preferred hemodialysis access but suffer from high rates of maturation failure and venous stenosis.
- These complications significantly hinder cannulation, complicating dialysis procedures.
Purpose of the Study:
- To review and discuss endovascular techniques for improving cannulation rates in AVFs.
- To present the available evidence supporting these interventional methods.
Main Methods:
- Coil embolization of accessory veins in immature AVFs.
- Balloon-assisted maturation for AVFs failing to mature.
- Fistuloplasty, stenting, and thrombectomy for mature but failing AVFs.
Main Results:
- Endovascular interventions offer solutions for both immature and mature failing AVFs.
- These techniques aim to enhance AVF patency and usability for dialysis.
Conclusions:
- Endovascular techniques are crucial for optimizing AVF function and overcoming common access-related complications.
- Further research and standardized application of these methods can improve dialysis outcomes.

01:25Hemodialysis I: Introduction
4.0K
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...

2.2K
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,...

3.4K
Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

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...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

2.3K
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...
