title: [New markings of central venous catheters, an improvement for localisation on x-ray pictures (author's transl)].
abstract: Despite the inweave of an X-ray positive thread the tip of a venous catheter is not always clearly delineated in the roentgenogram. The use of a new type of marking is considered to be constructive. The tip and further clearly identifiable equidistant markings along the length of the catheter are suggested. These facilitate an exact localisation of the catheter either directly or indirectly, and thus necessary corrections can be undertaken easily and exactly. Catheter fractures, embolisation of such fragments and extravenous placement of the catheter are immediately discernible. Furthermore we assume that X-ray dosage can be reduced and contrast medium accidents can be avoided.
