Catheter-related atrial thrombus in a patient on hemodialysis

[Exhaustion of vascular capital in patients on hemodialysis: what will be the outcome?]

Despite advances in the treatment of chronic renal failure, vascular access remains the weakest link in renal replacement therapy (RRT) and the leading cause of morbidity in patients on hemodialysis We report the case of a young female patient with chronic renal insufficiency secondary to vascular nephropathy on periodic hemodialysis and whose vascular capital was early exhausted due to iterative thromboses in arteriovenous fistulas and failure in peritoneal dialysis. Protein C deficiency was objectified. The patient underwent tunneled hemodialysis catheter insertion at the level of the right atrium via a right anterolateral thoracotomy with cannulation of the inferior vena cava, with poor functional outcome after three months of use. Since then she has been dialyzed using puncture of the external jugular veins.
