ABSTRACT
Embolisation of a catheter fragment is a rare mechanical complication of long-term central venous access devices. From 1995 to 1999 we observed 10 cases: the cause of embolisation was the ‘pinch-off syndrome’ in half of the cases, and in 8 cases out of 10 the fragment had embolised in the pulmonary arterial vessels. Percutaneous transvenous retrieval was successful in all cases; it was performed mainly (8 cases out of ten) through
the left transfemoral route, using a single-snare-loop device sometimes associated with a pig-tail catheter. We had no mortality and no major complications. On the basis of our experience, we believe that catheter embolisation of long-term central venous devices can be effectively prevented by adequate insertion technique, proper management of the device during its clinical use, and accurate removal technique. Nonetheless, should catheter em-bolisation occur, the patient should be referred to a Centre with adequate experience in the field of interventional radiological techniques. Should the radiological retrieval procedure fail, evidence from the literature suggests that leaving the fragment in embolisation site might be safer than open extraction by surgical thoracotomy, particularly in oncological patients with reduced life expectancy.
