Embolization of the stent to the right heart after a motor vehicle accident.

Endovascular stent grafts have become increasingly used in the management of arterial trauma, chronic vascular occlusive diseases, and deep vein thrombosis (DVT). Here, we describe a case of stent migration to the right heart due to a motor vehicle accident in a patient with iliac venous stent implanted for venous stenosis. Computed tomography (CT) scan imaging identification of a metallic stent was superior to the standard two-dimensional transesophageal echocardiography (TEE) techniques without imaging artifact from reverberation. However, real time three-dimensional (3D) TEE can precisely defined a metallic stent in right heart oriented with shape and direction without consuming time compared to that of CT scanning. The use of 3DTEE can facilitate identification of intracardiac metallic foreign bodies perioperatively in a patient with accident and emergent unstable condition. (Echocardiography 2010;27:587-589).
