Anomalous innominate artery complicating tracheal surgical procedures

Abstract

AbstractObjectiveTo highlight the importance of imaging in reducing an accidental injury to the anomalous brachiocephalic trunk and its branches during tracheal surgery.Case reportThis paper reports two cases of accidental injury to the great vessels in the neck during tracheal surgery. The first incident occurred during a repeat tracheostomy, when the right common carotid artery was injured. On reviewing the computed tomography images, the bifurcation of the brachiocephalic artery was seen to the left of the midline, and the right common carotid artery was adherent just below the tracheostomy site. The second incident happened during surgery for tracheal stenosis, when there was an inadvertent injury to the main brachiocephalic trunk, which was adherent to the trachea in the lower neck region.ConclusionFor airway surgeons, radiological assessment of vascular structures in relation to the trachea prior to surgery is as important as the endoluminal airway assessment for the best outcome.
