According to the reporter, hemodialysis was performed using a central venous hemodialysis catheter.It was reported that the patient was subsequently discharged to continue maintenance hemodialysis at an outpatient unit.However, it was not tolerated due to frequent episodes of intradialytic hypotension.It was indicated that the patient had several catheter exchanges, and developed progressive anasarca, dyspnea which prompting transfer for management of renal disease and refractory volume overload.A chest x-ray revealed small bilateral pleural effusions, and the right internal jugular dialysis catheter tip was reported to be in the superior vena cava.As part of the workup of pulmonary hypertension, a ct scan with pulmonary embolus protocol was done, which ruled out a pulmonary embolus.The study revealed the dialysis catheter to actually be in the ascending aorta rather than the superior vena cava.And a vascular surgery was consulted, and hemodialysis was temporarily held.Blood was drawn from the catheter and sent for blood gas analysis.This confirmed the intra-arterial position of the catheter, and the patient¿s coagulopathy was corrected.It was reported the patient underwent surgical removal of the arterial dialysis catheter with repair of the carotid artery at the catheter insertion site.A new tunneled dialysis catheter was placed in the left internal jugular vein under ultrasound guidance with catheter tip placement confirmed by fluoroscopy.
