The displacement of a shunt to a more distal arterial branch, along a path, is a rare complication. Vascular ultrasound can be presented as an excellent diagnostic modality for identifying the site of embolization of intravascular foreign bodies. The authors report a rare case of temporary shunt migration, implanted in the left common carotid artery, to left popliteal artery. The authors also describe the use of arterial vascular ultrasound to find the point of embolization, with an exact dermatography, that was essential to an easily surgical approach through a restrict and precise access way.
