An unusual case of common carotid artery pseudoaneurysm caused by migration of swallowed sewing needle

Abstract

Common carotid artery (CCA) pseuoaneurysms are most commonly a result of traumatic injuries. CCA pseudoaneurysm due to migration of ingested foreign body is an unusual occurrence. Here we report a case of a 50-year-old female who presented with a pulsatile swelling in the right lower neck for 2 months. Ultrasonography (USG) and Computed Tomography Angiography (CTA) of neck revealed a large partially thrombosed pseudoaneurysm involving the right common carotid artery. Sewing needle (metallic foreign body) was noted within the thrombosed portion of the pseudoaneurysm and was successfully removed at surgery followed by repair of the pseudoaneurysm.
