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.

In an area of palpable swelling on the left forearm, the radial artery shows an aneurysmatic enlargement with a length of approximately 2 cm and a width of about 1 cm on duplex sonography in this 53-year-old male patient (black arrow). It then becomes regularly narrower. Additionally, thrombotic deposits are shown in this region (white arrow)

Fig21: In an area of palpable swelling on the left forearm, the radial artery shows an aneurysmatic enlargement with a length of approximately 2 cm and a width of about 1 cm on duplex sonography in this 53-year-old male patient (black arrow). It then becomes regularly narrower. Additionally, thrombotic deposits are shown in this region (white arrow)

Mentions: Multiple punctures of the vessel wall can result in a circumscribed area in aneurysms or pseudoaneurysms. They can arise from venous segments or the original artery. Venous pseudoaneurysms have a low complication rate, but arterial pseudoaneurysms can cause a number of complications, such as ectasia, rupture, arterial thrombosis, and steal syndrome. Percutaneous ultrasound-aided thrombin injection is usually more effective than ultrasonic-assisted compression (Figs. 21a, b, 22 and 23a, b).Fig. 21
