title: Surgical importance of highly located innominate artery in neck surgery.
abstract: Massive hemorrhage is an unusual complication of tracheotomy, and the most common causes are injury to the anterior jugular veins and the thyroid isthmus, or unrecognized variations of the vascular structures, such as the arteria thyroidea ima. We present a case of high-running innominate artery that ascends until the third tracheal ring and courses horizontally anterior to the trachea in a patient with laryngeal carcinoma. If not noticed during tracheolaryngeal surgery, trauma to this vessel and subsequent hemorrhage may be fatal. In this report, the case is presented and the surgical significance of this anomaly is emphasized.
