High-located aberrant innominate artery: an unusual cause of serious hemorrhage of percutaneous tracheotomy.

An aberrant innominate artery located high was observed during a cadaveric neck dissection. To our knowledge, an innominate artery crossing the 4th and 5th tracheal rings has rarely been reported in available literature. Knowledge of this anomaly is important for those who are involved with percutaneous procedures in the neck to avoid major complications.
