Case: You inserted central line. While you were on your way to check CXR to confirm line placement, nurse request you to check KUB also to confirm enteral feeding tube placement (DHT). Interestingly, KUB shot this morning had IVC filter which is no more present there ?

Answer: Guide wire during central line procedure probably travelled into inferior vena cava and dislodged IVC filter !!!
