Dates available 11/18/2020 - 11/18/2021
“This activity is jointly provided by Global Education Group and Kidney Academy.”
This activity is supported by educational grants from Avenu Medical, BD (Becton, Dickinson and Company), and Medtronic.
The educational design of this activity addresses the needs of physicians and adjunct health care professionals (e.g., nurses, technologists) who treat kidney disease. Content is relevant to transplant surgeons, radiologists, interventionalists, and vascular surgeons.
Statement of Need/Program Overview
This module outlines basic principles for native vein AVFs. The wrist radio-cephalic anastomosis is described in detail as the surgical techniques are similar for different sites. Strict principles and meticulous practice of vascular surgical technique are paramount for success by in arteriovenous fistulas as patients are at high risk of uremia and renal failure associated comorbidity. While failure of an AVF may not be limb threatening as in other areas of vascular surgery the implications of a failed fistula may be wide reaching, particularly in younger patients adjusting to a lifetime of chronic disease. These techniques are covered in detail with short videos illustrating various anastomosis techniques.
Minimally Invasive Dialysis Access
Recent remarkable endovascular innovations have developed two minimally invasive procedures to create AVF fistula using one or two catheter techniques, respectively. Preliminary reports claim near 100 % technical success and a maturation rate in the 80-90 % range. This evolving technology has the potential to revolutionize hemodialysis access and is described in section 9. The percutaneous AVF placements parallels a similar more recent event in peritoneal dialysis (PD) namely the new Modified Seldinger technique for placement of PD catheters. A complete module 16 at www.kidneyacademy.com is covering the Percutaneous PD catheter placement. Together these technique have the potential to be gamechangers in dialysis access in the near future. Both percutaneous hemodialysis and percutaneous PD technique rely heavily on the skillful use of ultrasound described in detail in module 15 at www.kidneyacademy.com
After completing this activity, the participant should be better able to:
Explain the need for an integrated patient-centric model and functional infrastructure to manage RRT patients.
Recognize the value of an outcomes tracking system to assess performance and improvement.
Explain the function of ultrasound vascular mapping.
Describe vascular anatomy for selection of vessels appropriate for AVF.
Define atraumatic surgical techniques required to minimize initial hyperplasia such as juxta-anatomical stenosis.
Describe the benefits of an arteriovenous fistula in appropriately selected patients.
List the various types and selection of operative sites.
Identify the characteristics for a successful or mature arteriovenous fistula.
Identify the optimal time for arteriovenous fistula creation appropriate specialist referral path.
Describe the basic principles for evaluating a patient’s suitability for AVF, including physical exam and preoperative mapping with ultrasound.
Discuss the lesions associated with early arteriovenous fistula failure.
Outline principles in the evaluation of newly placed arteriovenous fistula to predict maturation.
Discuss the treatment of early arteriovenous fistula failure.
Describe the lesions associated with late fistula failure.
Outline fistula pathology, including high blood flow cardiac impact and implications of excessive blood flow management in an AVF.
Explain aneurysm formation and how to prevent them through proper cannulation techniques.
Describe the innovations for percutaneous placement techniques of AVFs.
Describe the value of simulation training and opportunities available for AVF.
