Radiological imaging is often used for the preoperative localization of foreign body following blast injury, but their utility in case of migration during intra-operative period is limited. Transesophageal echocardiography (TEE) has been used for intra-operative localization and removal of intra-cardiac foreign body; however, reports for localization of extracardiac migrating foreign body are few. Preoperative radiological imaging, in a victim of factory blast-injury, suggested foreign body in the posterior mediastinum. However, the intra-operative TEE showed it in the left atrium, which later migrated into the left ventricle necessitating a change in surgical approach for its removal. [ABSTRACT FROM AUTHOR]
