Understand different available options for hemodialysis, including arteriovenous (AV) grafts, AV fistulas, hemodialysis catheters, and peritoneal dialysis, including the benefits and downsides of each method
Understand the normal imaging appeareance on MDCT of AV grafts and fistulas, including different potential locations for their placement and their relationship to adjacent vasculature.
Understand proper construction of a CT protocol designed to evaluate a graft or fistula
Recognize a number of complications of grafts and fistulas that may be visible on MDCT.
1. Introduction
Different types of hemodialysis access options available and their appropriateness in different situations
Detailed discussion of grafts and fistulas, including the manner in which they are placed and the difference between grafts and fistulas
2. Anatomy
Locations in which grafts and fistulas can be placed
Different possible vascular communications which can be created

3. MDCT appearance of normal grafts and fistulas.
4. Complications which can be recognized on MDCT, with case examples
Stenosis
Thrombosis
Aneurysms/Pseudoaneurysms
Ischemia/Steal syndrome
Infection
