Dialysis access pseudoaneurysm: endovascular treatment with a covered stent.

Iatrogenic pseudoaneurysms of the brachial artery are rare complications of haemodialysis access procedures and can lead to substantial morbidity and mortality if not managed promptly; however, surgery is also associated with the potential risk of severe complications. We describe the clinical and radiological findings relating to a dialysed patient who developed a huge iatrogenic pseudoaneurysm of the brachial artery (due to an inadvertent artery puncture), which was successfully treated by means of the percutaneous implantation of a polytetrafluoroethylene (PTFE)-covered stent.
