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: Hernias are a frequent complication because of an increase in intra-abdominal pressure and peritoneal defect generated by the catheter implantation, which occur in up to 25 % of the cases of dialysis patients, mostly umbilical next to the peritoneal dialysis catheter and in the inguinal channel [53]. They can lead to a dialysate leak and incarcerations and strangulation of bowel loops, which usually require surgical intervention (Figs. 17 and 18).Fig. 17
