This case involves an elderly man who underwent revision surgery to correct an earlier procedure to implant a pacemaker. During the procedure, doctors attempted to place a line into the patient’s jugular vein in order to administer blood products, however it was discovered to be occluded. As a result, the surgeon elected to place a line in the subclavian vein instead. After the surgery was completed, the patient was brought out of the operating room and placed into the intensive care unit, where he experienced a seizure. Subsequent testing and evaluation discovered that the line had been placed into the patient’s artery rather than the vein, however, no evidence of an embolus was discovered on imaging studies, nor was any evidence of stroke. The patient continued to suffer from moderate encephalopathy after being released from the hospital, allegedly due to injuries suffered during the pacemaker revision surgery.
