[Extraction of foreign bodies (catheters) from the right atrium and the abdominal aorta by the percutaneous route. Report of 2 cases and review of the literature].

Two cases of catheter-fragment embolism from a peripherical vein into the cardiac cavities and their extraction by means of a modified technique are presented. In the first case, the foreign body was located in the right cavities of the heart and it was extracted employing a modified technique by means of a Pigtail catheter and a Bioptom sequentially introduced percutaneously. In the second case, the embolus was located in the abdominal aorta and was extracted percutaneously with a Fogarty catheter. A review of the literature is made and, owing to the increasing frequency of the use of intravascular catheters, some recommendations are made in order to avoid this kind of complications.
