Abstract Central venous catheter implantation for hemodialysis is commonly performed in large centers and its complications are sometimes associated with insufficient training of those who perform it, but may also be related to the patient’s clinical condition. The present study reports two cases of complications related to use of a short-stay catheter for hemodialysis. In the first case, the cannula was inadvertently inserted into the left subclavian artery, causing arterial thrombosis, which was conservatively managed and good collateral perfusion was documented with vascular echography. The second case illustrates an incidental finding of Central Venous Septic Thrombosis in a patient who had used a catheter for a week, which was treated with antibiotic therapy, anticoagulation, and ultrasound control. In both cases, surgical intervention would have been high risk because of the patients' poor prognosis. Vascular ultrasonography enabled monitoring of these clinical situations and use of less aggressive treatments.
