Definition An uncommon–up to 1% of cases–but serious complication of long-term placement of central venous catheters—CVCs, in which the catheter fragments and embolises through the heart into the pulmonary artery. POS occurs when a long-term CVC is compressed between the clavicle and the first rib, causing transient obstruction of the catheter, potentially causing a tear or even complete transection and embolisation of the catheter.
Synonyms Catheter fragmentation with subsequent embolisation, POS
