Retrieval of intravascular foreign bodies

In this communication we describe the different techniques that are used to remove foreign bodies from various locations within the heart or vascular tree. A brief review of the literature concerning the reported complications from retained foreign bodies is made to underline the importance of early percutaneous removal of these fragments.
