Summary
Duplex ultrasound evaluation (DUE) is a cost-effective, non-invasive tool for selecting and maintaining dialysis access. It aids in choosing the best access type and site, and diagnosing complications for effective management.
Area of Science:
- Nephrology
- Vascular Surgery
- Radiology
Background:
- Dialysis access selection and maintenance are crucial for long-term patient outcomes.
- History and physical examination are primary steps in assessing dialysis access needs.
- Established dialysis accesses require ongoing monitoring for complications.
Purpose of the Study:
- To present a practical decision-making algorithm for dialysis access using duplex ultrasound evaluation (DUE).
- To highlight the role of DUE in selecting optimal dialysis access modality and site.
- To emphasize DUE's utility in diagnosing and managing vascular access complications.
Main Methods:
- Review of the application of duplex ultrasound evaluation (DUE) in dialysis access.
- Description of pre-operative vascular mapping using DUE.
- Outline of DUE's role in assessing established dialysis accesses and complications.
Main Results:
- Duplex ultrasound evaluation (DUE) is a cost-effective, non-invasive screening tool for dialysis access.
- Pre-operative DUE facilitates the selection of optimal dialysis access modality and site.
- DUE effectively diagnoses the majority of vascular access complications in established accesses.
Conclusions:
- Duplex ultrasound evaluation (DUE) is integral to both the initial selection and ongoing management of dialysis access.
- DUE guides appropriate surgical or interventional radiology management for vascular access issues.
- Implementing a DUE-based algorithm optimizes dialysis access longevity and patient care.

01:25Hemodialysis 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...
01:24Imaging Studies II: Ultrasonography
IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...
01:24Hemodialysis 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,...
01:25Hemodialysis 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...
01:27Dialysis
Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

01:15Dialysis
Dialysis is a diffusion-based purification process that separates analyte molecules from a complex matrix. This is accomplished by allowing molecules in the solution to pass through a semipermeable membrane into a liquid on the other side. The membrane is usually made of cellulose acetate or cellulose nitrate, and the second liquid must be miscible with the solution. Ions (e.g., chloride or sodium) or organic molecules (e.g., glucose) can pass through the membrane pores, which generally have...
