Intravascular Foreign Bodies : what the Radiologist Needs to Know

The intravascular foreign bodies (IFBs) can originate from many sources both iatrogenic and noniatrogenic; as the frequency of endovascular therapies increases, the incidence of lost or embolized iatrogenic foreign bodies is also increasing. As IFB can cause significant complications such as thrombosis, pulmonary and peripheral embolism, etc. It is therefore necessary to remove them, and this may be accomplished through surgery or by means of percutaneous radiologic techniques. Percutaneous approach is widely perceived as the best way to retrieve IFB. We provide an overview of recent literature, clarifying what devices are being lost, what symptoms occur as a result, and how retrieval is being performed.
