Abstract
In daily clinical practice, the radiologist in the context of diagnosis often faces dialysis-associated complications. The complications are numerous and range from infections, catheter dysfunctions, haematomas, cardiovascular diseases, digital ischaemia, and pseudoaneurysms to shunt stenosis. In this pictorial essay, we take a close look at the imaging diagnostics of the most common complications in dialysis patients.
Teaching Points
• The occurrence of venous stenosis in haemodialysis patients is up to 41 %.
• Catheters usually have a fibrin sheath that can be rinsed but not aspirated.
• The steal phenomenon occurs in 75–90 % of patients with a shunt system.
• Arterial pseudoaneurysms can cause a number of complications.
