Radiological diagnosis of dialysis-associated complications.

Zandieh S, Muin D, Bernt R, Krenn-List P, Mirzaei S, Haller J - Insights Imaging (2014)

Bottom Line: 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.

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.

Mentions: Dysfunction is usually caused by incorrect position of the central catheter. Thus, no adequate blood flow can be generated. The usual procedure attempted is to reposition the catheter. If this is not possible, the implantation of a new catheter is necessary. The localisation is usually determined based on an x-ray (Figs. 3, 4a, b, 5, 6 and 7a, b).Fig. 3
