Extrusion of a coil from the internal carotid artery through the middle ear.

چکیده
In August 2002, we were consulted about a case in which a 70-year-old man found a long wire coming out of his left ear (Fig 1). He had a history of nasopharyngeal carcinoma, which had been treated with radiotherapy 7 years previously. Although radiotherapy had eliminated the carcinoma, it caused left temporal bone radionecrosis and temporal lobe necrosis. The patient had presented to ear, nose, and throat surgeons with profuse left ear bleeding 7 months before the wire extrusion. Digital subtraction carotid angiography revealed that a large pseudo-aneurysm had arisen from the proximal petrous part of the left internal carotid artery (ICA) [Fig 2]; contrast agent was also actively extravasated. The haemorrhage was controlled by embolising the pseudoaneurysm with 16 Guglielmi detachable coils (GDC). The patency of the left ICA was preserved with the use of stentassisted coiling and two metallic stents. Post-embolisation angiography confirmed complete occlusion of the pseudoaneurysm and preservation of left ICA flow. There was no further bleeding from the left ear and the patient was discharged home 1 week later.
