The following were reviewed as part of this investigation: patient severity, complaint and batch history, applicable previous investigation(s), applicable manufacturing records, radiographic image analysis and applicable fmea documents.Based on a review of this information, the following was concluded: the complaint of low visibility of the catheter was confirmed but the cause is unknown.A single front chest radiograph was returned for evaluation of this complaint.There was a left sided central line that was seen up until the mediastinum where the quality of the image reproduction prevented evaluation for the tip.The catheter appeared to be in the correct position, but the original image would need to be windowed and leveled to be sure.The exact cause of the low visibility of the catheter could not be determined but may have been affected by multiple factors including the image reproduction, the radiopacity of the catheter, patient build, machine setting, the technique of image acquisition, rotation of the patient, and overlapping structures.A lot history review (lhr) of refp4091 showed nine other similar product complaint(s) from this lot number.
