Abstract

Haemodialysis catheters are frequently used in patients with end-stage renal failure prior to the formation of an arterio-venous shunt. Right atrial thrombus can developed in some patients receiving haemodialysis through indwelling central line venous catheter (CVC). Thrombus formation can developed in response to intraluminal clot formation or endothelial damage in the right atrium caused by the constant friction between catheter and right atrial wall. Three patients developed right atrial thrombus after undergoing haemodialysis due to end stage renal failure. Out of three cases of RAT, one of them was infected. The three cases managed medically. No surgical intervention was required. The indication for routine echocardiographic screening in patients with hemodialysis catheter might be an option to detect RAT earlier; however, its role will remain controversial due to the cost reasons.
