Intraoperative localization and monitoring of migrating foreign body using transesophageal echocardiography

Abstract

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.
